Security/GRC Domain Skills To Include * Vulnerability findings and remediation workflows. * Evidence collection and evidence sufficiency. * SSPs, POA&Ms, control mappings, audit packages, and risk acceptance. * NIST 800-53, RMF, FedRAMP/FISMA, CMMC, SCRM, ZTA, ISCM, and related compliance concepts. * Scanner output from tools such as cloud security scanners, vulnerability scanners, SAST/IaC tools, secret scanners, identity/M365 scanners, and web security scanners. * Provenance, auditability, and defensibility requirements for regulated workflows. AI/LLM Product Skills To Include * Experience building AI-assisted product features, preferably in security, compliance, document review, or workflow automation. * Understanding of RAG, embeddings, document extraction, prompt/context design, and evidence citation. * Ability to enforce scoped context, provenance, guardrails, and human-review boundaries. * Comfort maintaining provider abstractions across local and cloud AI providers. Infrastructure And Operations Skills To Include * Docker Compose for local development. * AWS-style production operations: containers, managed databases, caches, object storage, CDN, IAM, logs, and deployment pipelines. * Terraform or similar infrastructure-as-code experience. * CI/CD debugging and release discipline. * Observability, logs, health checks, and operational runbooks. What Would Be Nice To Have: * Prior experience with GRC, audit automation, security consulting tools, vulnerability management, FedRAMP/FISMA, or SSP/POA&M workflows. * Experience with generated OpenAPI SDKs. * Experience producing PDF, Excel, DOCX, PowerPoint, or audit package exports. * Experience with immutable audit logs, provenance chains, multi-tenant permissions, or evidence workflows. ## Description We are hiring a senior engineer to maintain and extend a large full-stack Governance, Risk, and Compliance platform. The product is not a simple scanner wrapper. The current codebase includes a substantial FastAPI backend, a React/TypeScript frontend, a PostgreSQL data model, an async worker system, scanner integrations, an AI provider abstraction, a compliance framework catalog, audit/reporting workflows, and local/cloud deployment infrastructure. The ideal candidate can work confidently across backend services, frontend workflows, database migrations, security controls, AI-assisted analysis, scanner ingestion, and production operations. * Maintain and extend a FastAPI backend with hundreds of registered API routes. * Build and refine React/TypeScript product workflows across a large frontend surface. * Design and maintain SQLAlchemy models, Alembic migrations, PostgreSQL queries, and data integrity rules. * Support scanner integrations, finding normalization, deduplication, evidence workflows, and compliance mapping. * Maintain AI-assisted features through a centralized provider abstraction rather than direct calls to providers. * Work across GRC workflows including findings, evidence, SSPs, POA&Ms, RMF, FedRAMP/FISMA, SCRM, ZTA, ISCM, risk acceptance, and reporting. * Keep local development and test environments healthy using Docker Compose, Redis, PostgreSQL, worker queues, Ollama, observability services, and frontend tooling. * Maintain quality gates including linting, type checking, OpenAPI drift checks, migration safety, SDK drift, architecture boundaries, and test suites. * Debug issues across frontend state, API contracts, database state, workers, scanner output, generated SDKs, and deployment configuration. * Treat documentation as helpful but secondary to the codebase; validate assumptions against source, tests, migrations, and running behavior.
