Sr. Software Engineer, Vendor Semantics and Developer ; Remote

About the Role

As the Senior Software Engineer, Vendor Semantics & Developer Experience, you will be the primary builder of a system that treats global infrastructure as a formal graph, where every node and edge is traced back to a versioned source of truth. Our Ontologists design the formal architecture of what truth looks like. Our Knowledge Engineers build the frameworks and transformation engines that make that truth computable.

You are the engineer who keeps that system honest and usable. Your domain is vendor semantic data: the OpenAPI, Swagger, and Smithy specifications that describe what cloud providers, security tools, and infrastructure platforms expose to the world.

Own the Vendor Schema Registry: build and maintain the systems that ingest, parse, and version vendor API specifications. Track schema evolution across providers, detect breaking and semantic changes, and ensure that the canonical ontological model stays synchronized with the ground truth of what vendors actually expose.

Build the Semantic Validation Pipeline: implement validation systems that verify new and updated vendor schemas against the canonical ontology, catching mapping gaps, type conflicts, and semantic regressions before they propagate into the graph.

Build the Developer

Experience:

design and maintain the internal tooling, SDKs, scaffolding, and documentation systems that make it fast and safe for product teams and ingest engineers to work with the knowledge platform.

Close the Loop Between Schema and Graph: work closely with the Knowledge Engineers and Ontologists to translate real-world vendor schema constraints and edge cases into actionable input for the canonical model.

Raise the Floor for Downstream Teams: invest in the documentation, tooling, and validation guardrails that allow product and ingest teams to move quickly without deep knowledge of the underlying semantic systems.

• A strong software engineering background with 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 – built internal tooling, SDKs, or frameworks that engineers use, measuring success by their productivity.
• A rigorous, correctness-first engineering mindset: thinking in terms of in variants, edge cases, and vendor changes.
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows, and drive business outcomes.

• Experience building systems that track and diff API specification changes over time (schema registries, changelog automation, breaking-change detection).
• Familiarity with semantic web technologies (RDF, SHACL, OWL, SPARQL) or ontology engineering tool chains.
• A background in infrastructure, cloud platform engineering, or security tooling, understanding how cloud providers think about their APIs.
• Experience with declarative configuration systems or code generation pipelines that translate high-level intent into low-level artifacts.
• A track record of making complex internal systems more approachable, such as writing tools or guides that make teams faster.

• Market leader in compensation and equity awards.
• Comprehensive physical and mental wellness programs.
• Competitive vacation and holidays.
• Paid parental and adoption leave.
• Professional development opportunities for all employees.
• Employee Networks, geographic neighborhood groups, and volunteer opportunities.
• Vibrant office culture with world-class amenities.
