About the role

Key responsibilities & impact
  • Work side-by-side with the concept architect to convert advanced system ideas into technical specifications, service maps, data models, APIs, schemas, tests, and deployment plans.
  • Translate verbal and written design guidance into architecture diagrams, implementation backlogs, acceptance criteria, and working prototypes.
  • Identify ambiguity, missing assumptions, engineering risks, security issues, and implementation conflicts.
  • Help turn an evolving concept architecture into reproducible, testable, maintainable software.
  • Build production-grade Python services, APIs, data pipelines, background workers, and orchestration logic.
  • Design clean service boundaries for ingestion, entity resolution, evidence management, review workflows, reporting, audit logging, and model integration.
  • Design and implement relational schemas, graph models, object-storage structures, retrieval indexes, and audit records.
  • Build canonical identity and entity-linking systems that reconcile conflicting real-world records.
  • Support relationship topology, ownership mapping, provider-network analysis, and source-conflict preservation.
  • Integrate model-serving infrastructure such as vLLM, KServe, Ray Serve, and Hugging Face, or equivalent tools where appropriate.
  • Deploy services using Docker, Kubernetes, Helm, GitOps, CI/CD, RBAC, secrets management, observability, and secure environment practices.

Requirements

What you’ll need
  • 8+ years of professional software engineering experience, or equivalent exceptional experience.
  • Expert-level Python engineering.
  • Experience building production backend services, APIs, data pipelines, and distributed systems.
  • Strong SQL and relational database design experience, preferably PostgreSQL.
  • Experience with graph databases, knowledge graphs, or complex relationship modeling.
  • Experience with LLM integration, open-weight models, structured outputs, prompt/template management, or model-evaluation workflows.
  • Experience with Docker, Kubernetes, Helm, GitOps, CI/CD, and secure cloud or private infrastructure deployment.
  • Experience with data validation, audit logging, RBAC, secrets management, and secure software design.
  • Ability to design modular systems from ambiguous early-stage architecture.
  • Ability to translate non-engineering conceptual guidance into concrete software architecture and implementation plans.
  • Strong written documentation skills.
  • Comfort working directly with a non-engineer concept architect.
