Do we have a match?

As a Senior Software Engineer, you must meet the following criteria:

Strong, 7+ years professional experience with modern Python - we run 3.14 and stay close to the latest release
Experience building and maintaining software products for external customers
Experience owning an architecture end to end, including the part where you align teams you have no authority over
Hands-on, everyday use of AI coding tools in your engineering workflow, with a considered view of where they earn their keep and where they do not
Solid testing experience and ability to pick the right testing strategy
Experience building and maintaining integrations or API clients
Experience with data modeling and transformation - parsers, intermediate representations, schema-driven conversion or similar
Fluency with Pydantic and with strict static typing (mypy or equivalent) as a daily discipline
CI/CD experience
Comfortable in a fast-paced environment where priorities are set as much by customers as by the backlog
Open for technical challenges and open-mindedly looking for technical solutions to business problems
Very good command of English (ideally C1 level) - spoken and written

Beyond the criteria above, we would appreciate the following:

Experience with workflow or orchestration engines (e.g. Temporal)
Experience with Docker and Kubernetes
Experience with SQLAlchemy, or ORM-based data modeling more broadly
Experience with migration, import or ETL-style tooling
Experience with asynchronous Python
Experience with XML at scale, or grammar-based configuration parsing (e.g. TextFSM)
Experience with Go
Experience with observability tooling (e.g. OpenTelemetry, Prometheus, Grafana)
Experience with modern Python packaging and tooling (uv, ruff)
Working understanding of core networking concepts (TCP/IP, VLAN, NAT, ACL, firewalls, routing)

The project and the team

You will join a team co-developing a unified network security management platform from a leading cybersecurity vendor. You will be building functionality that automates and facilitates the conversion and onboarding of existing network security estate configurations within that platform.

The solution's foundation rests on several years of experience delivering large-scale migration projects that would not have been possible without specialized automation software. That expertise, together with AI-assisted development, helps the team move fast and consistently land high-quality results.

As the software keeps expanding and becoming a fully-fledged product, we're looking for another Senior Software Engineer to help build what's next. It is as much a product engineering challenge as a technical one.

Other things to know:

The team consists of software engineers and network security SMEs who share strong ownership of code and product quality
AI tools are part of the daily workflow
This is a backend-focused role
We are a distributed, fully remote team

We work on multiple interesting projects at a time, so it may happen that we'll invite you to an interview for another project if we see that your competencies and profile are well suited for it.
