AI Engineer (Mid-Level)

About this role

ABOUT THE ROLE

We're a small, fast-moving team building the next generation of AI-driven products that automate complex, multi-step workflows across regulated and enterprise domains — think healthcare, legal, fintech, logistics, and compliance. As a Mid-Level AI Engineer on our core product team, you'll work across the full stack to ship production LLM-based services, own critical infrastructure, and collaborate directly with founders and product to deliver real, measurable user impact.

This is a high-ownership role on a lean team. You'll touch everything from data models and APIs to agent orchestration and evaluation infrastructure — and you'll see your work in the hands of users quickly.

WHAT YOU'LL DO

- Design, build, and maintain agentic systems that automate complex, multi-step workflows across regulated industries including healthcare, legal, fintech, logistics, and compliance.

- Own production retrieval-augmented generation (RAG) pipelines and retrieval infrastructure — vector DBs, embeddings, and indexing — for domain-specific search at scale.

- Implement multi-agent orchestration, tool-calling, memory, and reasoning components to deliver robust AI-driven user experiences.

- Develop evaluation and safety infrastructure to measure model performance, surface regressions, and enforce enterprise-level trust and reliability.

- Ship full-stack AI products from MVP to enterprise-grade: design APIs and data models, implement frontend and backend code, and operate production systems with CI/CD, monitoring, and testing.

- Collaborate closely with founders, product, and design to prioritize work, define success metrics, and iterate based on user feedback and telemetry.

WHAT WE'RE LOOKING FOR

Must-haves:

- 2+ years of software engineering experience with a track record of shipped, user-facing or backend products.

- Hands-on experience deploying LLMs or LLM-based services in production, including prompt design, orchestration, and tool integration.

- Full-stack proficiency: Python plus TypeScript/React (or equivalent); experience with AWS or GCP and relational or NoSQL databases.

- Working knowledge of RAG patterns, vector databases, embeddings, and retrieval pipelines with sound judgment on when to apply each.

- Experience building automated tests, evaluations, and monitoring for AI systems to ensure production reliability beyond demos.

- Experience designing API-driven, high-throughput systems and real-time product features.

Nice-to-haves:

- Experience with agent or workflow frameworks (e.g., LangGraph, CrewAI) and orchestration tools (e.g., Temporal, Trigger).

- Background building multi-tenant or enterprise-ready systems, or prior experience in regulated industries (healthcare, fintech, legal).

- Familiarity with fine-tuning, parameter-efficient tuning, or multi-modal model integration.

- Up to 8 years of total engineering experience — seniority range is wide; ownership mindset matters more than years.

COMPENSATION & BENEFITS

- Salary: $180,000 – $400,000 USD annually (range reflects experience and equity mix)

- Early-stage equity in a pre-seed company with strong investor backing

- Visa sponsorship: Not available
