Senior Software Engineer with Python

As a part of the project team, you will be responsible for:

• Designing, building, and maintaining the software product and the underlying libraries
• Building a self-service product: with actionable errors, predictable behavior, and a path a customer can complete without specialized assistance
• Deciding what gets generalized and what gets built once - some capability is shared, some is specific, and keeping that cost curve falling is the central architectural judgment in this role
• Owning and leading technical initiatives to successful delivery, from the design document through to release
• Acting as the technical counterpart to the teams around you - raising dependencies early and in writing, rather than discovering them at integration time
• Maintaining appropriate test coverage and helping shape the overall testing strategy
• Applying AI-assisted engineering practices and setting the standard for how they are used - across the entire SDLC, not only in code generation
• Contributing to architecture and design decisions as the solution scales in different dimensions
• Proposing and helping ship your own ideas for improving the product, beyond your core delivery work

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)
