Full Stack Developer

Residency

All applicants must reside in the United States at the time of application.

Overview

BigBear.ai is building a small, elite development team that delivers cloud-native applications directly supporting mission operations. This is a focused, high-impact environment where your work is highly visible and directly influences outcomes. We’re seeking a mid-level Full Stack Developer with strong Python backend skills and solid frontend craftsmanship who thrives in classified environments and brings a disciplined engineering mindset to building secure, maintainable systems under real operational pressure.

What you will do

You will design, build, and deliver end-to-end mission applications—from database schema and migrations to API layers and the user experience mission users rely on daily. You’ll support an established platform while also delivering pilot solutions and MVPs for emerging requirements.

Extend Python services and APIs using modern patterns (including Backend-for-Frontend when appropriate)

Build and refine React/Next.js interfaces and dashboards for operational workflows.

Design PostgreSQL schemas, create migrations, and troubleshoot performance issues

Integrate authentication/authorization using OIDC/SAML-based solutions (e.g., Keycloak), including RBAC and secure token/session handling

Deploy and operate applications in AWS environments (including classified regions/partitions)

Contribute to infrastructure-as-code (Terraform) and CI/CD (GitLab) in a DevSecOps pipeline

Review and remediate security scan findings with guidance from team standards (SAST/SCA and container scan results), and document fixes for reuse

Use approved AI-assisted development tools to improve velocity and quality while protecting sensitive data

What you need to have

Active TS/SCI clearance

3+ years of hands-on software development experience (or equivalent demonstrated capability)

Strong Python development experience (Django, FastAPI, or similar) and modern API design practices

Hands-on frontend development with React (Next.js a plus) for production systems

Experience working with REST APIs, schema/contract validation (e.g., Pydantic-style), and writing maintainable tests

Working knowledge of PostgreSQL (schemas, migrations, basic query performance troubleshooting)

Practical experience delivering or operating applications in AWS (e.g., IAM, VPC basics, S3, KMS concepts; EKS/Aurora exposure is a plus)

Familiarity with Git-based workflows and CI/CD fundamentals (GitLab experience is a plus)

Security-minded engineering approach (least privilege, secrets handling, secure coding practices) and willingness to remediate findings from scanning tools

Ability to work effectively on a small team: clear communication, strong ownership, and comfort with ambiguity

What we'd like you to have

Experience integrating Keycloak or similar IAM tools; familiarity with OIDC, SAML, JWT, and RBAC concepts

Exposure to CAC/PIV authentication considerations in DoD/IC environments

Comfort contributing to Terraform modules and infrastructure changes with review support

Experience in STIG-hardened and/or FIPS-validated environments (or strong interest in learning)

Kubernetes/EKS and Helm familiarity

Experience supporting DoD or IC mission systems

Exposure to GenAI application features (RAG, LLM integration, embeddings/search)
