Senior Software Engineer (Python)

Quick Facts

• Role: Senior Software Engineer (Python)

• Focus: Backend integrations, discovery agents/workers, and declarative data ingestion APIs

• Team: Small cross-functional team; distributed across Europe and the US

Description

You will join the team behind a network source-of-truth (NSoT) platform used to model, document, and automate network infrastructure. You’ll build integrations with third-party network systems and controllers, develop discovery agents that extract device/interface/topology data, and deliver that data through the platform’s declarative ingestion layer. The platform is AI-first and supports AI-assisted development and testing.

Responsibilities

• Design, build, and maintain integrations connecting the platform to third-party network systems and controllers

• Develop discovery agents/workers to securely connect to customer infrastructure and extract device, interface, and topology data

• Build and maintain services and APIs that deliver discovered data into the declarative ingestion layer

• Write and maintain unit tests (pytest) and contribute to E2E test automation (Playwright via Docker Compose and CI)

• Apply AI-assisted engineering practices to make development and testing faster and more reliable

• Collaborate closely with a small, cross-functional engineering team

• Propose and help ship ideas to improve the platform beyond core integration work

• Contribute to architecture and design decisions as the platform scales

• Write clean, maintainable, well-tested code and participate in code reviews

Requirements

• Strong professional experience with Python

• Hands-on, everyday use of AI coding tools (ideally Claude Code)

• Experience building and maintaining integrations or APIs (REST)

• Solid unit testing experience (ideally pytest)

• Fluency with Docker and Docker Compose

• Experience with Kubernetes

• Working understanding of core networking concepts: IP vs MAC, VLANs, VRFs, DNS, BGP, ACLs

• Experience with relational databases (PostgreSQL/SQL)

• Comfortable in a startup-like, fast-paced, proactive environment

• Experience with monitoring tools (Grafana and/or Prometheus)

• CI/CD experience (ideally GitHub Actions)

• Experience with cloud computing (ideally AWS: EC2, S3, EKS)

• Good knowledge of English (minimum C1)

Benefits

• Flexible working hours; fully remote, office, or hybrid

• Professional growth with internal training sessions and a training budget

• Hands-on onboarding

• Supportive atmosphere among professionals

• Ability to switch projects
