What this job asks for AI summary
This role centers on designing and building a design-by-contract framework in Python — creating decorator-based contract classes, an AST-level verifier, and CI integration that enforce predicates and invariants on code as it evolves. A secondary responsibility involves extending a canonical Avro schema and adapter layer that normalizes ML annotation data from multiple labeling platforms. It suits an engineer with strong Python internals knowledge and comfort with formal, abstract structures like type systems and program analysis.

Why we read it this way (9)
The posting describes a fixed-term engagement ('by end of term', '30/90 day' milestones, knowledge-transfer goal of team ownership) — treated as Contract rather than full-time.
Location is hybrid in Westbrook, OR or fully remote (CT hours mentioned as a reference timezone). CBSA mapped to Portland-Vancouver-Hillsboro, OR-WA as the nearest metro to Westbrook, OR.
No overall years-of-experience requirement is stated. Seniority assessed as Senior based on the scope: independent ownership of a novel framework, collaboration with a senior architect, and expectation of autonomous delivery.
A CS degree is explicitly listed under Bonus Qualifications ('A computer-science degree, or any particular number of years of experience') — not a hard requirement.
Deep Python (decorators, descriptors, metaclasses, type hints) and AST-based analysis are the core hard gates drawn from the required qualifications section. Avro is called out as the shipped canonical schema the candidate must extend, making it a hard gate despite also appearing in the bonus stack list.
All design-by-contract tooling (icontract, deal, Eiffel, JML, Dafny), property-based testing (Hypothesis), parsing tools (libcst, tree-sitter), mypy, OPA/Rego, Pydantic/Marshmallow/attrs, JSON Schema/OpenAPI/LinkML/CUE, Databricks, Spark, and dbt are listed under Bonus Qualifications or as 'genuine plus' items.
The alt SOC (15-1243 Database Architects) reflects the secondary focus on schema design and evolution for the annotation data platform, but the primary day-to-day work is clearly software development (framework design, AST verifier, CI integration).
Posting is for a contract engagement — the market benchmarks below price full-time roles, so read the comp comparison with that in mind.
This posting reads as a fully-remote role, so it was scored against the national candidate pool rather than a single metro.
