Founding Engineer, AI & ML Systems

FilmoreAI is the intelligence layer for the construction equipment industry a multi-hundred-billion-dollar economy where dealers manage every stage of the machine lifecycle (acquisition financing utilization service trade-in disposition) on data that lives in a dozen disconnected systems and a thousand reps heads.

Were building the data and AI system that fixes that. Were building equipment domain specific reasoning using a propietary ontology that connects ERP work orders CRM opportunities OEM telematics UCC filings auction results and DMS transactions into a single canonical model of every machine every customer every dealer interaction across the lifecycle. Aftermarket where dealers earn the majority of their profit on tribal knowledge is where the data is messiest and the leverage is highest so its where we lead.

The data system is the product. We parse public information across all 50 states including UCC liens construction projects contractors and early land development. We normalize telematics across OEM standards. We resolve entities across systems that have never spoken to each other.

Agent infrastructure. Design and ship the agent runtime. Wire agent templates to live data through the canonical schema and the internal MCP tool registry. Build workflows in LangGraph with typed I/O structured outputs retries and observability versioned and tested like backend services not prompt notebooks. Implement the staged trust ladder for write-back read-only human-approved scoped autonomous with every action logged in the Postgres action ledger alongside the reasoning trace and a rollback path.

Model layer & routing. Own the in-house Model Router across Claude GPT Gemini and OSS. Make the live calls on when Opus is worth the cost when Haiku is enough when Geminis long context is the unlock and when an OSS model is the right call. Prompt caching failover provider-concentration risk eval-gated rollouts the model layer is a production system and you operate it like one.

LLM-powered extraction & reasoning. Build extraction and reasoning workflows over filings work orders spec sheets and other semi-structured or unstructured documents using vision and long-context models. Design typed schemas with Pydantic iterate on prompts as document formats change and keep the cost / latency / accuracy tradeoff explicit including when an LLM is the wrong tool and a parser or regex is. Build the golden sets and evals that let you ship changes with confidence.

Canonical data model. Migrate and extend the canonical schema. Entity resolution across dealer systems telematics public records transaction histories and third-party data is a primary ongoing problem here and the schema is the compounding moat for every agent we build on top. Maintain the OLTP plane in Azure Database for PostgreSQL (with pgvector) cleanly separated from the OLAP plane in Synapse; know which workloads belong where and why.

Data pipelines & cloud orchestration. Build and maintain Python ingestion across public third-party and partner sources government registries filing systems geospatial APIs permit and contract systems. Handle the real-world failure modes: rate limits schema drift auth flows JS-rendered sites with Playwright. Operate the stack on Azure Container Apps Blob Storage Container Apps Jobs Temporal Cloud for long-running jobs approval queues and human-in-the-loop write-back paths.

What Were Looking For

LLM APIs in production (3 yrs). Youve shipped real systems with Anthropic OpenAI or Gemini designed extraction schemas built agentic workflows written evals reasoned about cost/latency/accuracy at scale. You can tell a war story about a model regression you caught before the customer did.

Modern agent stack. LangGraph (or equivalent typed agent framework) Pydantic AI MCP pgvector golden-set evals prompt caching. We dont expect all of these we expect you to learn the ones you dont and have opinions about the ones you have.

Strong Python (5 yrs). Production-grade service and pipeline code other engineers can read extend and trust six months later. Async typing packaging the boring parts done right.

SQL & Postgres (5 yrs). Schema design migrations query optimization materialized views index strategy. You read EXPLAIN plans without flinching. Bonus: dbt and a modern warehouse (Synapse Snowflake Databricks).

Cloud deployment (5 yrs). Azure preferred (Container Apps Blob Storage Azure Database for PostgreSQL Synapse Analytics); GCP or AWS translate. Youve shipped to production not just dev.

Messy real-world data. Inconsistent schemas pagination edge cases auth flows dynamic JS-rendered pages document parsing. Youve debugged a scraper at 2am because a vendor changed their HTML.

Modern data agent stack familiarity. Temporal LangChain LangGraph Pydantic AI pgvector MCP. We dont expect all of these we expect you to learn the ones you dont.

Strong plus: public/government/third-party data sources enrichment pipelines with fallback logic document extraction at scale.

You operate without supervision. We hand you a problem not a ticket. You scope it ship it and tell us when we got the problem statement wrong.

You navigate ambiguity. The spec changes mid-week the data is weird and the customer feedback contradicts the design doc. You know when thats healthy startup velocity and when its a signal somethings broken.

You ship the smallest thing that proves the bet. Manual version first. Build the API only when it earns its place. Walk away from problems that dont move the dealers P&L.

Youre calibrated and bias toward action. When you dont know you say so. When the data is wrong you flag it. When an LLM output is suspect you dont ship without guardrails. Then you keep moving.

You care about why this exists. Dealers run their businesses on tribal knowledge and relationships. Were building the platform layer to help them modernize without implementing. If that mission doesnt pull you forward the rest of this wont.

You drive agentic IDEs as your primary loop. Claude Code Cursor or equivalent not autocomplete full agent sessions. You give the agent a problem the right context and the constraints then review its work like a tech lead reviewing a strong junior. You know when to let it run and when to take the keyboard back.

You run agents in parallel. Multiple worktrees multiple sessions multiple branches in flight one agent migrating a schema another writing tests another drafting docs. Youve adapted your planning review and merge discipline to a world where throughput isnt bounded by what one human can type.

You design context not prompts. You know an agent with the right files schema examples and acceptance criteria does excellent work and one with a clever prompt and no context does not. You write / agent specs / project rules the way youd write a runbook because youll run them a hundred times.

You orchestrate agents like services. Typed I/O structured outputs retries tool registries (MCP) golden-set evals end-to-end observability. LangGraph workflows are version-controlled tested and instrumented like backend services. Not prompt engineering. Software.

You reason about the model layer in production. When Opus is worth the cost when Haiku is enough when Geminis long context is the unlock when an OSS model is the right call. Routing failover prompt caching provider concentration risk tradeoffs youve made for real not in theory.

Small team direct founder access decisions get made fast. Async-first clear PR descriptions and run summaries no standup theater. Every line of code accumulates proprietary data or makes the reasoning layer smarter; youre expected to apply that filter too.

Competitive pay equity as early employee. Open to contracting and scope / hours if preferred.

To apply: email with
(1) one or two data systems youve built what you were solving what made it hard how you handled it
(2) how youve used LLMs in production with real data or real users not demos
(3) the messiest data source youve worked with and what it taught you
