LLM features that ship, with evals so they don't drift.

Hiring an AI engineer in Boston? Senior ML / LLM engineers run $300K+ here and the pipeline is shallow. We ship AI features instead — chat UI, RAG, agents, evals — on a flat-price engagement that goes live in 2–5 weeks.

The local read

Why hiring a ai engineer in Boston is hard

Boston founders have access to the best deep-tech talent in the country and almost none of it is hireable at seed stage. Biotechs pay above market for ML engineers. Cambridge robotics shops pay close to that for ROS 2 specialists. The local agency option is mostly enterprise consulting with multi-quarter contracts.

We're not enterprise consulting. One senior engineer owns the build, Eastern Time, overlap with your MIT advisors and Boston-based investors. FHIR or HL7 for healthtech. PyTorch and Hugging Face for ML features. Next.js for the SaaS layer. Flat-price quote in 24 hours. Code in your GitHub from commit one.

A senior ai engineer here is a ~$448K year-one outlay after benefits, payroll tax, and the 60–90 day search. We're a $8,000+ flat engagement that starts inside seven days.

Why this beats a hire

One AI-native engineer.
The output of a team.

One senior ai engineer plus AI agents now ships what four engineers used to. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in Boston who need to ship before the next round closes.

Two paths in Boston

The work, concretely

What we'd own day to day

The same scope you'd hand to a salaried ai engineer, owned end to end on a flat-price engagement. No coordination overhead, no junior-on-the-bench, no estimation theatre.

  • Chat / agent UI with streaming, interrupt, retry, citations done right
  • RAG: chunking, embeddings, hybrid search, reranking, citation-required prompts
  • Multi-provider routing via Vercel AI Gateway — primary + fallback + cost rules
  • Evals as a CI gate, not a vibe check — held-out test set, regression alerts
  • Cost observability — token spend per route, model tiering, caching

FAQ

About hiring vs engaging in Boston

How fast can you start?

+
Most engagements begin within seven days of the first call. There's no recruiter pipeline, no notice period, no relocation timeline.

Which model provider?

+
Default to Anthropic Claude (Sonnet most cases, Haiku for cost-sensitive paths, Opus for the hard ones). All routed via Vercel AI Gateway so you can switch without code changes.

Is this a full-time replacement?

+
No — we're a senior engineer on a flat-price engagement. For most pre-seed and seed-stage products, that ships more than a salaried hire would in the same window. When you outgrow it, we hand off cleanly to the team you hire.

How do you handle hallucinations?

+
Evals on a held-out test set in CI, citation-required prompts where factuality matters, structured outputs (JSON schema) where machine-parsable answers are needed.

Who owns the code?

+
You do, from commit one. Repo in your GitHub, infra in your cloud account. When you do hire someone, they onboard onto your code, not ours.
