Senior Platform Engineer

Senior Platform Engineer

Who You Are: You're a senior engineer who makes production reliable and makes shipping safe and routine. As Citian's first dedicated platform engineer, you'll shape how we run CRASH and ADAPT, which state and local governments rely on every day. You take an AI-first approach: you multiply the rest of engineering by building tooling, automation, reusable skills and agents, rather than becoming a queue. You're a self-starter who takes ownership and works well across teams. You can work remotely within the US or hybrid in our Washington, D.C. office.

Expected Duties: Design, build and run CI/CD pipelines that reliably build, test, deploy and roll back our applications, with versioned releases and deployment records.

Stand up on-call, runbooks and a lightweight incident process, and take part in the on-call rotation.

Set up monitoring, error tracking and alerting for applications and scheduled data pipelines, so we find problems, including missed runs, before customers do.

Own infrastructure as code, environments and cloud cost, including bringing hand-built infrastructure into code.

Assess our tooling (CI/CD platform, container orchestration, infrastructure as code, branching and release strategy) and lead changes where they pay off.

Administer PostgreSQL (RDS), Snowflake and S3, including backups, tested restores, access, performance and cost.

Build internal tooling, reusable skills and agents that help engineers build, test, deploy and operate safely.

Set service-level objectives with product and customer success, and report against them.

Help build and operate AWS GovCloud environments for government customers with CJIS requirements.

Set platform standards, build security controls into them with engineering leadership and our SOC 2 program, and mentor engineers on operating what they build.

Required Skills & Experience: Bachelor's degree in Computer Science, Engineering, Information Systems, or a related technical field

7+ years running production systems, 4+ of them on AWS (IAM, networking, RDS, S3, CloudWatch)

Infrastructure as code (Terraform, AWS CDK, CloudFormation or similar)

Designing and running CI/CD pipelines with reliable deploys and rollback (GitLab CI, Jenkins, GitHub Actions or similar)

Containers and orchestration (Docker; Kubernetes/EKS or ECS)

Database administration in production (performance tuning, backup and restore, migrations)

Observability: metrics, logs, traces and alerting

Experience leading incident response and running postmortems

Operating in a compliance environment (SOC 2, GovRAMP/FedRAMP, CJIS, HIPAA or similar): change control, access reviews, audit evidence

Strong Python or TypeScript for building tools, and hands-on agentic coding (Claude Code or similar): breaking work into agent-sized tasks, writing specs and tests agents can work against, and reviewing agent output critically
