À propos de ce poste Senior AI Engineer chez Metaforms
About Metaforms
Market research runs on 30-year-old survey platforms and armies of specialists hand-coding questionnaires in proprietary languages. Metaforms is the agent layer that does that work. Every survey is a program — full of skip logic, piping, quotas, and loops — and a single wrong number in a client report is unrecoverable. Our AI agents write production survey code, QA live deployments, process and clean large structured datasets, configure analysis, and generate client-ready reports, so agencies like Dynata, Savanta, and Borderless Access ship more projects with far less friction.
1,000+ surveys processed monthly
Serving Fortune 500 companies across the globe
Rapid month-over-month growth
We’re Series A funded and scaling fast, aggressively growing our AI engineering team to build the next generation of production-grade AI agent systems.
The Role
We’re hiring a Senior AI Engineer to own the design, development, and continuous improvement of the AI agent systems that power modern research operations.
This is a high-ownership, high-impact role at the intersection of applied AI and systems engineering. You’ll work on genuinely hard problems: agent reliability at scale, long-context handling, cascading error mitigation, and evaluation infrastructure — like codegen agents that write in proprietary DSLs, computer-use agents that QA live deployments, data agents that clean tabular exports and configure multi-step analysis, and evals for outputs where “correct” is genuinely ambiguous. And you’ll do it on a team that ships fast and treats quality as non-negotiable.
What You’ll Own
Agent Harness and Architecture
Own the agent harness our production agents run on — the loop where agents plan, use tools, check their work, and recover from failures
Lead research and implementation for long-context handling and cascading-error challenges in multi-step agent pipelines
Drive context engineering strategy and experimentation frameworks across the team
Evaluation and Production Monitoring
Define structured rubrics for evaluating AI outputs on nuanced, ambiguous research tasks
Build continuous monitoring, tracing, and failure-mode analysis for agents in production — including the loop that turns production failures into test cases
Create tooling that lets domain experts refine and evolve the skill files, eval sets, and knowledge bases our agents consume
Reliability for High-Stakes Outputs
Build eval suites — regression sets, golden datasets, LLM-as-judge pipelines — that catch regressions before deploy
Develop evaluation datasets for DSLs, structured data transforms, and computed outputs to systematically find and close model weaknesses
Design human-in-the-loop and review workflows for outputs where a single wrong number in a client report is unrecoverable
What We’re Looking For
Must-Have
Built and operated agentic systems in production — multi-step pipelines, tool use, codegen, computer-use, or data and reporting agents — not just prototypes
4+ years of engineering experience, with at least 1 year focused on LLM/agent systems in production
Deep hands-on experience with frontier model APIs (Anthropic, OpenAI, Gemini), evaluation frameworks, and AI system optimization
Strong Python skills; Go or TypeScript a plus
Solid grasp of context engineering and evaluation methodology
Strong instincts for debugging complex, non-deterministic system failures
High ownership: you drive problems to resolution independently and pull others in when it matters
Nice to Have
Experience with LLM observability and eval tooling (Braintrust, Langfuse, LangSmith, Weave, promptfoo, or in-house equivalents)
Background in semantic parsing, DSLs, or structured-output generation
Prior work on computer-use or browser agents
Experience with human-in-the-loop agent workflows where proposals are reviewed before apply, or agents over large structured datasets
Why Metaforms
Work at the frontier of production AI: systems handling 1,000+ research projects a month, with the reliability bar that implies
A small, senior team where your decisions carry real architectural weight
Zero-bureaucracy culture: high autonomy, fast feedback loops, direct access to leadership
Well-funded and financially stable, with a clear roadmap and the runway to execute on it
Benefits
Full family health insurance
$1,000 USD annual learning and development budget
Dedicated mentor and coaching support
Free snacks and dinner at the office
