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 disciplineCI/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 GoExperience 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)
