Job summary

Pulley is building AI-powered permitting infrastructure in the SF Bay Area and beyond. This senior AI engineer role focuses on turning messy permitting inputs into fast, structured outputs with end-to-end ownership—from data intake to production features and monitoring.

You will shape the product surface with LLMs, work on evaluation and observability, and mentor teammates while delivering reliable, customer-facing capabilities. Remote options exist in coordination with in-person days.

Qualifications

• 4+ years of software engineering experience with a focus on production ML/LLM systems.
• End-to-end ownership of an LLM-powered product surface, from requirements to production.
• Deep hands-on experience with large language models in production.
• Experience designing evals to ensure reliability and quality of features.
• Experience building AI coding agents and shipping agent-driven workflows.
• Based in the SF Bay Area and willing to work in person 4 days a week.

Responsibilities

• Own AI-powered features end-to-end—from user interactions to production deployment.
• Turn unstructured permitting documents and regulations into structured outputs via extraction and classification.
• Build evaluation and observability foundations to measure quality and detect regressions.
• Work with AI agents as a daily practice, directing and shipping agent-driven work.
• Make technical and product decisions that directly impact customers and projects.
• Mentor engineers and raise the bar for quality and velocity.

About Pulley

Pulley helps the country’s top architects, builders, and retailers speed up every project in their portfolio. With AI-powered permitting intelligence and expert guidance, we eliminate costly delays and bring predictability across the full lifecycle of commercial projects.

Today, permitting is the slowest, most uncertain part of building, spread across 19,000+ jurisdictions with different rules, timelines, and surprises. Pulley gives project teams the clarity and predictability they need to move from planning to opening without delays.

We support rollout programs for brands like J.Crew, Solidcore, and Hibbett Sports, as well as major data center buildouts, EV charging networks, and other commercial projects. Our platform dramatically reduces approval timelines, improves forecasting accuracy, and removes thousands of hours of manual work from design and construction teams.

Founded in 2021, Pulley combines deep permitting expertise with purpose-built AI from people who have created products used by millions. We’re backed by CRV, Susa Ventures, Fifth Wall, and leaders from Plaid, Segment, ServiceTitan, and Procore.

WHAT YOU’LL DO

In this role, you will build the intelligence behind the product that gets stuff built. Permitting runs on messy inputs—scanned plan sets, jurisdiction code, reviewer comments, application forms that differ in every city—and turning that into something fast, structured, and trustworthy is the core technical problem at Pulley. As a senior-level AI engineer, you will:

Own AI-powered features end-to-end—from talking to users and defining what “correct” means for a permitting workflow, through prompt and pipeline design, evals, deployment, and iteration in production

Turn unstructured permitting documents, city regulations, and jurisdiction workflows into structured, reliable outputs—extraction, classification, retrieval, and agentic workflows over documents that were never designed to be machine-readable

Build the evaluation and observability foundation that lets us ship LLM-powered features with confidence: define ground truth, measure quality and regressions, and know when a model change is actually an improvement

Build with AI agents as a daily practice—directing, reviewing, and shipping agent-driven work at high velocity while owning the quality bar

Make technical and product decisions that have direct impact on our customers and their projects

Raise the bar for the engineers around you in how they build with LLMs, through design review, mentorship, and the standards you set in your own work

WHO YOU ARE

You thrive in ambiguity—you’d rather define the right problem than execute a spec, and you’re energized rather than paralyzed when the path isn’t laid out

You’re product-minded: you care whether the thing you built actually solved the customer’s problem, and you’ll talk to users to find out

You’re rigorous about what “working” means—you don’t trust a demo, you trust an eval, and you build the measurement before you build the feature

You have strong opinions about quality and velocity and don’t treat them as a tradeoff—you look for the tools, abstractions, and processes that buy both

You default to ownership: when something is broken or missing, your instinct is to fix it, not to file it as someone else’s problem

NEED TO HAVE

4+ years of software engineering experience, with a substantial portion building production LLM or ML systems

Track record of owning an LLM-powered product surface end-to-end: requirements through production, including the unglamorous parts—data quality, eval design, cost and latency, failure handling

Deep hands-on experience with large language models in production—prompting, retrieval-augmented generation, structured extraction, tool use and agentic workflows, and knowing when each is the wrong tool

Experience designing evals and otherwise making LLM-powered features reliable in production

Real experience building with AI coding agents—not just autocomplete; you’ve shipped work where agents did substantial implementation under your direction

Ability to architect durable systems while making pragmatic tradeoffs

Based in the San Francisco Bay Area and willing to work in person 4 days a week

NICE TO HAVES

Experience with document understanding at scale—OCR, layout-aware parsing, or vision-language models over scanned PDFs, drawings, or forms

Experience fine-tuning models or building data pipelines to produce training and eval sets from real-world usage

Experience in construction tech, govtech, proptech, or another domain where the hard part is messy real-world documents and processes

Experience with modern full-stack development—we use TypeScript, React, and Google Cloud—and an appetite for working in the application code that puts AI features in front of users

Startup experience at the stage where you helped build the team, not just the product

Experience mentoring engineers or leading technical direction across teams

Compensation Range: $230K - $280K
