Data Engineer, Red Tape Index - Labrynth

Labrynth accelerates progress by streamlining regulatory complexity. We build AI-powered platforms that navigate complex regulations, generate audit-level documentation, and provide certainty, not shortcuts. Our technology serves clients across heavily regulated industries including energy, compliance, and government regulations.

We operate as a forward-deployed engineering organization: small, high-velocity teams embedded directly with clients to rapidly discover needs and ship production-quality solutions.

We are hiring a Data Engineer to build the data platform behind our regulatory indices: acquiring fragmented public data, transforming it into clean, auditable datasets, and constructing the index methodology that turns it into published rankings.

This is a data platform role more than a pure pipeline or backend role. You will sit close to the raw sources and close to the math. The work spans three modes:

• Acquire: source data from fragmented and often hostile places, including government open-data portals, APIs, HTML, PDFs, legacy Excel formats, login-protected portals, and commercial sites behind anti-bot protection.

• Transform: normalize inconsistent jurisdictional data through bronze → silver → gold pipelines with idempotent ingestion, content hashing, and run-level lineage.

• Construct: turn clean data into transparent, auditable indices through winsorization, percentile ranks, weighting, composites, and sensitivity testing.

• Ship scrapers and ingestion flows against messy, sometimes adversarial sources, using HTTP/2 clients, TLS-fingerprint evasion, and browser automation fallbacks, and keep them resilient as sources change

• Own Postgres schema design and migrations end to end across per-country and per-domain schemas

• Build and maintain medallion (bronze → silver → gold) transforms that are idempotent, content-hashed, and lineage-tracked

• Implement and defend index methodology: normalization, weighting, and composite construction where the math verifiably says what it claims (our scoring core is held to 100% test coverage)

• Assess data feasibility early, clarify requirements with partners, and convert ambiguous index ideas into executable plans

• Take an index end to end: sourcing, validation, methodology, publication, and refresh planning

• Operate pipelines on our orchestration stack (Prefect dispatching per-flow ECS Fargate tasks) with observability everywhere

Our stack is deliberately modern (Python 3.14, uv, ruff, ty, polars, Prefect 3, marimo). We don't filter on those exact tools; we hire for Python and data depth and expect a short ramp.

• Strong Python and SQL; you have designed Postgres schemas and owned migrations (SQLAlchemy and Alembic, or equivalents) in production

• Data pipeline experience with a lakehouse/medallion mindset: idempotent ingestion, content hashing, and lineage are habits, not aspirations

• Web scraping beyond requests: anti-bot evasion, browser automation, and resilience against messy or hostile sources

• Statistics literacy for index methodology: winsorization, normalization, weighting, and sensitivity testing, and you can reason about whether an index's math supports its claims

• Comfort with modern Python tooling and CI discipline: typing, linting, coverage gates, and conventional commits

• Product discovery instincts: you talk with partners in plain language, assess data feasibility before committing, and flag what is proven versus assumed

• End-to-end ownership: you are a pragmatic generalist who moves across data, backend, infrastructure, and basic product decisions in an uncertain environment

• Prefect experience, or Airflow/Dagster with willingness to switch

• AWS (ECS, S3) and Terraform

• polars, pyarrow, and marimo or a Jupyter background

• LLM-in-pipeline experience (pydantic-ai, AWS Bedrock, evals)

• Actuarial, quantitative research, or data science background in ranking or index construction

• Experience with government open data (permits, energy, environmental, or economic datasets)

• Comfort working alongside AI tooling; our repos are agent-forward (Claude agent teams, spec-driven docs)

• High-impact work at the intersection of AI and critical infrastructure regulation

• End-to-end ownership of indices, from raw source to published methodology

• Small team with outsized influence; your feasibility calls shape what we build

• Modern AI-native development environment (Claude Code, Cursor, multi-model orchestration)

• Remote-first

• Competitive compensation

• Character: integrity and trustworthiness above all

• Competency: evoking trust and reliably delivering

• Togetherness: family-level support and alignment

• Impact: meaningful outcomes over activity

• Commitment: ownership and follow-through
