Our Challenge

Your Challenge

• Design and deliver production-grade evidence collectors that pull compliance evidence directly from our security, cloud, and identity tooling — configuration, scheduling, normalization, failure handling, and alerting included.
• Productize the collector framework so that adding the next integration is a well-trodden path rather than a new project.
• Take the remaining platform modules through to production cutover: role-based access from identity-provider claims, admin and audit-logging hardening, and enabling writes back to upstream systems.
• Build agentic evidence collection: an AI “compliance specialist” that interprets a control, designs and executes a review procedure over REST APIs and MCP servers, interacts with control owners in our collaboration tools, and hands its work to a mandatory human review gate.
• Keep the platform boringly reliable — database parity and migration safety in CI, observability, performance, and remediation of internal AppSec findings before anything reaches production.
• Work in the open with our Security & Compliance team: small frequent PRs, tests with the code, ADRs for decisions worth remembering, and documentation that outlives the engagement.

Our Tech Stack

• Backend: Python, FastAPI, SQLAlchemy + Alembic, APScheduler
• Data: PostgreSQL in deployment, SQLite locally and in CI
• Cloud & delivery: Docker on AWS (ECS/ECR), AWS Secrets Manager, Terraform, GitHub + GitHub Actions
• Integrations: REST APIs across our security, cloud, identity, and collaboration tooling; OIDC SSO; MCP servers for agentic workflows
• AI-assisted development: the codebase is built with AI coding tools and we expect you to use them — with full ownership of what you merge

What we are looking for:

• Senior backend experience with strong Python (FastAPI, SQLAlchemy/Alembic), or equivalent depth in a comparable stack and the appetite to work in ours.
• A track record of integrating third-party REST APIs in production: auth flows and token handling, pagination, rate limits, webhooks, retries, and the failure modes that only show up at 3 a.m.
• Working knowledge of AWS (ECS, Secrets Manager, IAM basics) and Docker; able to read and adjust Terraform.
• Strong testing habits and comfort in a documentation-heavy, review-driven workflow.
• A security mindset: least privilege, secret hygiene, and care when handling confidential data.
• Fluent English; Czech is welcome but not required.

Nice to have

• Hands-on experience with SIEM/SOC or security tooling APIs.
• Exposure to GRC and compliance automation (SOC 2, ISO 27001) or products like Vanta or Drata.
• Experience building LLM-agent workflows with tool use, or with Jira, Slack, or Notion APIs.
• Experience with observability stacks (Grafana, Prometheus).

Engagement details

• Contract (B2B/IČO), time & materials, monthly invoicing
• Part-time, 0.5 FTE (approx. 10 man-days per month)
• ASAP through 31 December 2026, with extension into 2027 by mutual agreement
• Remote within the EU, possible to work also from our Prague office
