Senior Software Engineer, Vendor Semantics, Developer Experience

Key Responsibilities

• Own the Vendor Schema Registry: You will build and maintain the systems that ingest, parse, and version vendor API specifications like OpenAPI, Swagger, Smithy, and others.
• Build the Semantic Validation Pipeline: Correctness, not throughput, is your SLO.
• Build the Developer Experience: You will design and maintain the internal tooling, SDKs, scaffolding, and documentation systems.
• Close the Loop Between Schema and Graph: You will work closely with the Knowledge Engineers and Ontologists.
• Raise the Floor for Downstream Teams: You will invest in the documentation, tooling, and validation guardrails.

Requirements

• A strong software engineering background with hands-on experience building systems that parse, validate, and transform structured specifications or schemas at scale.
• Proficiency in Go, Rust, and/or Python; comfort in polyglot environments.
• Deep experience with API specification formats – OpenAPI/Swagger, Smithy, JSON Schema, or similar, including parsing, diffing, and reasoning about schema evolution.
• A practical understanding of graph data models and the downstream consequences of upstream schema decisions.
• A demonstrated instinct for developer experience; you have built internal tooling, SDKs, or frameworks that other engineers actually used, and you measure success by their productivity.
• A rigorous, correctness-first engineering mindset: you think in terms of invariants, edge cases, and what happens when a vendor silently changes something.
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency, and drive business outcomes.

Core Competencies

Demonstrates expertise in building and maintaining systems for parsing and validating API specifications, with a strong focus on developer experience and correctness. Proficient in Go, Rust, and Python, with a deep understanding of API specification formats and graph data models.
