Founding Engineer - AI
Who You Are
A true builder with 4+ years of technical experience. You’ve lived the 0→1 chaos - maybe you co-founded something, or led a team through the trenches. You know that the good (fast growth) and the ugly (2 AM patches) come with the territory. You’re scrappy, curious, and energized by uncharted problems.
Why It Matters
- Shape a category. No one owns “pre-con” yet and we’re charting that map.
- Bridge two worlds. Effect changes in an estimator’s spreadsheet with multimodal models that understand construction documents.
- Direct impact. Your AI agents will help contractors close multi-million-dollar bids and save hundreds of hours per project.
Your Mission
Build agentic workflows that work. Create agents to complete multi-step construction tasks. Implement tool use for Procore APIs, Excel manipulation, and document generation. Build agents that read plans, update budgets, and generate RFIs autonomously.
Ship production RAG systems. Process 1,500-page plan sets. Build pipelines that understand construction specs and drawings. Handle messy, real-world documents - scanned, rotated, hand-marked. Deliver semantic search that actually finds the door schedule on page 347.
Embed with customers. Sit with estimators during bid week. Understand workflows, then turn “we manually compare 50 subcontractor bids” into an intelligent agent.
Own the AI stack. Python services orchestrating model calls. Celery workers for long-running jobs. Vector DBs for semantic search. Context engineering, evaluation frameworks, and monitoring for quality. Dockerized workloads on GCP infra.
Make AI reliable. Build evaluation datasets from real construction docs. Collaborate with SMEs to catch hallucinations and make models accurate enough for million-dollar decisions.
Tech Stack
AI/ML: LLM APIs, Agentic frameworks, RAG pipelines, Vector DBs, Langfuse
Backend: Python (FastAPI), Celery, Node.js/TypeScript
Infra: GCP, Docker, Supabase
Data: PDF parsing, spreadsheets, computer vision, unstructured data pipelines
Who Should Apply
We want hands-on builders with 4+ years of experience delivering applied AI to real users. You might be:
A Full-Stack Engineer hacking with LLMs who wants to go deeper
A Forward Deployed Engineer who wants to build AI, not just integrate it
An ML Engineer who wants to ship products, not just models
A Data Scientist tired of notebooks who wants to ship production code
A Founding Engineer or ex-CTO ready for the next challenge
You'll Stand Out If You Have
Built and deployed an AI feature with real users
AEC industry experience
Worked with computer vision or advanced OCR pipelines
Fine-tuned a model with a custom-built datasets
Roles involving coding + customer interaction (FDE, Solutions Engineer, etc.)
Prior founding-team or 0→1 experience
Real Talk
You’ll own customer and agent implementations end-to-end.
You’ll ship to production within days, not weeks.
Specs will be half-baked - you’ll fill in the blanks.
You’ll wear many hats: dev, architect, product, recruiter, and support hero.
If you love making AI solve real problems for real people, you’ll thrive.

Founding Account Executive (AE)
About The Opportunity
As our Founding Account Executive, you’ll drive Muro’s growth from founder-led sales to a scalable GTM engine. You’ll own deals end-to-end — from discovery to close — working with the founders to define our ICP, refine messaging, and make “Muro it” a phrase known across the construction world.
Why it matters:
Shape a category. No one owns “pre-con AI” yet - we’re charting that map
Bridge two worlds. We’re redefining how construction meets AI — you’ll bridge human expertise with AI automation to transform how the industry works
Drive impact. Every deal you close helps bring automation to an industry that still runs on spreadsheets
What You’ll Do
Own the full sales cycle - from prospecting and pipeline generation to negotiation, close, and onboarding - across mid-market and enterprise clients (typically $50K+ ACV)
Build and run multi-threaded sales campaigns engaging both operational leaders (Preconstruction Directors, Estimators) and C-suite executives
Conduct deep discovery to understand client workflows, pain points, and ROI opportunities, translating them into tailored solutions and measurable outcomes
Deliver compelling demos and proposals, connecting Muro’s AI capabilities to tangible preconstruction efficiency and cost savings
Collaborate closely with founders and GTM leadership to refine ICP, messaging, and pricing, and to build scalable sales playbooks and processes
Represent Muro at key industry events and conferences to drive awareness, pipeline growth, and category leadership in “Pre-Con AI.”
Partner cross-functionally with Product and Engineering to relay customer insights, shape new use cases, and influence the product roadmap
Basic Qualifications
2+ years of full-cycle closing experience in SaaS or fast-growing startups
Proven track record of exceeding quota, closing $50K–$100K+ ARR deals
Skilled in solution selling - you focus on outcomes and ROI, not features, and can tailor value to each customer’s workflow and priorities
Strong communicator and storyteller — able to make complex AI or workflow products simple and compelling
Highly organized and detail-oriented, with disciplined CRM hygiene (HubSpot experience a plus)
Coachable, curious, and driven to grow in a fast-paced, early-stage environment
Thrives in high-ownership, ambiguous settings and knows how to create structure where none exists
Preferred Qualifications
Experience selling SaaS or AI solutions; selling to General Contractors or within the construction industry is a plus
Proven ability to manage complex, high-value sales cycles (>$100K contracts)
Strong understanding of construction workflows and buyer dynamics in preconstruction or operations
Experience engaging with senior decision-makers and representing the company at industry events, trade shows, or conferences
Familiarity with modern outbound tools such as Lemlist, Clay, and LinkedIn Sales Navigator
What You'll Get
Ownership & Impact: Play a pivotal role in shaping how the construction industry adopts AI — your work will directly influence our growth and success.
Speed & Urgency: We move fast and operate with high ownership — we raise the bar for ourselves and each other every day.
Competitive compensation with a top-of-market base, uncapped commission, and benefits
Growth Environment: Continuous learning, mentorship, and clear paths to advance as we scale our GTM team

Founding Account Executive (AE)
(004)
Chief of Staff
We’re looking for a CEO Multiplier — part strategist, part operator, part chaos coordinator, and part professional “Of course, this too should be a part of my job from today” person.
You will work directly with the CEO across everything that matters to an early-stage startup:
• Strategy
• Sales
• Investors
• Product
• Hiring
• Partnerships
• Random fires that appear on Tuesday mornings
Some days you’ll help shape the future of AI in construction. Other days you’ll be figuring out why a contractor in Texas emailed us a 600-page bid package at 11:47 PM.
Both have their own importance.
What You’ll Actually Do
This role is designed for someone who likes variety, speed, and solving new problems every day.
You might be:
Strategy & CEO Office
• Helping the CEO turn big ideas into actual execution
• Preparing for investor meetings, board conversations, and strategic partnerships
• Turning messy startup thoughts into clear plans
Sales & Growth
• Supporting enterprise sales conversations with general contractors
• Preparing materials for demos and pilots
• Helping refine messaging for AI agents in pre-construction
Operations
• Running special projects across product, GTM, hiring, and partnerships
• Making sure important things actually happen (a rare startup superpower)
Product & Market Insight
• Talking to contractors, estimators, and innovation leaders
• Turning market feedback into actionable insights for the team
Founder Multiplier
• Making the CEO 10x more effective
• Being the person who asks the question everyone else forgot
What Makes This Role Fun
You’ll get a front-row seat to build a company.
You’ll see:
• Investor conversations
• Product decisions
• Customer deals
• Market strategy
• Startup chaos in its natural habitat
You’ll also get to work in an industry where:
• Skyscrapers get built
• Billion-dollar projects start with a spreadsheet
• And AI is about to change everything
Who This Role Is Perfect For
You might be a great fit if you:
• Love solving problems that don’t have a playbook
• Enjoy working very closely with founders
• Can switch between strategy, operations, and execution
• Are curious about AI, startups, and large real-world industries
• Like learning 10 new things every week
Backgrounds that tend to thrive here:
• Consulting
• Startup operations
• Product strategy
• Venture / investing
• Construction tech
• Or someone who just gets things done
Bonus Points If
• You enjoy turning chaos into systems
• You like working with builders (both software and buildings)
• You ask questions like
“Is this the smartest way to do this?”
• You enjoy occasionally explaining AI agents to construction executives
What You’ll Get
• A front-row seat to building an AI company
• Exposure to founders, investors, and industry leaders
• The chance to help shape the future of a Trillion industry
• Startup speed, responsibility, and learning
Also:
Probably more construction acronyms than you expected.
Final Note
Startups are not always tidy.
Some days are strategic.
Some days are chaotic.
Some days both happen before lunch.
If that sounds exciting, you’ll probably love this role.
Apply if you want to help build the AI layer for the precon world.

Founding Account Executive (AE)
(004)
Chief of Staff
We’re looking for a CEO Multiplier — part strategist, part operator, part chaos coordinator, and part professional “Of course, this too should be a part of my job from today” person.
You will work directly with the CEO across everything that matters to an early-stage startup:
• Strategy
• Sales
• Investors
• Product
• Hiring
• Partnerships
• Random fires that appear on Tuesday mornings
Some days you’ll help shape the future of AI in construction. Other days you’ll be figuring out why a contractor in Texas emailed us a 600-page bid package at 11:47 PM.
Both have their own importance.
What You’ll Actually Do
This role is designed for someone who likes variety, speed, and solving new problems every day.
You might be:
Strategy & CEO Office
• Helping the CEO turn big ideas into actual execution
• Preparing for investor meetings, board conversations, and strategic partnerships
• Turning messy startup thoughts into clear plans
Sales & Growth
• Supporting enterprise sales conversations with general contractors
• Preparing materials for demos and pilots
• Helping refine messaging for AI agents in pre-construction
Operations
• Running special projects across product, GTM, hiring, and partnerships
• Making sure important things actually happen (a rare startup superpower)
Product & Market Insight
• Talking to contractors, estimators, and innovation leaders
• Turning market feedback into actionable insights for the team
Founder Multiplier
• Making the CEO 10x more effective
• Being the person who asks the question everyone else forgot
What Makes This Role Fun
You’ll get a front-row seat to build a company.
You’ll see:
• Investor conversations
• Product decisions
• Customer deals
• Market strategy
• Startup chaos in its natural habitat
You’ll also get to work in an industry where:
• Skyscrapers get built
• Billion-dollar projects start with a spreadsheet
• And AI is about to change everything
Who This Role Is Perfect For
You might be a great fit if you:
• Love solving problems that don’t have a playbook
• Enjoy working very closely with founders
• Can switch between strategy, operations, and execution
• Are curious about AI, startups, and large real-world industries
• Like learning 10 new things every week
Backgrounds that tend to thrive here:
• Consulting
• Startup operations
• Product strategy
• Venture / investing
• Construction tech
• Or someone who just gets things done
Bonus Points If
• You enjoy turning chaos into systems
• You like working with builders (both software and buildings)
• You ask questions like
“Is this the smartest way to do this?”
• You enjoy occasionally explaining AI agents to construction executives
What You’ll Get
• A front-row seat to building an AI company
• Exposure to founders, investors, and industry leaders
• The chance to help shape the future of a Trillion industry
• Startup speed, responsibility, and learning
Also:
Probably more construction acronyms than you expected.
Final Note
Startups are not always tidy.
Some days are strategic.
Some days are chaotic.
Some days both happen before lunch.
If that sounds exciting, you’ll probably love this role.
Apply if you want to help build the AI layer for the precon world.
