Job Description Position DetailsSalary:EUR 70k annual base salary, with VSOP available for discussionWorking Hours:Daytime working hours aligned with Central European Time (CET)Work Setup:Fully remote positionRole Summary We are hiring aSenior Python Developerto lead design and implementation across astateful, workflow-driven platform built in Python . This role requires strong backend engineering fundamentals and the ability to work confidently acrossapplication logic, APIs, integrations, asynchronous processing, state management, testing, and production architecture .You will work on a platform that combines:Python services and core runtime designFastAPI-style HTTP APIs and callback endpointsRedis-backed state and workflow persistenceAsync external-provider integrations and retry handlingMulti-channel messaging backendsLLM-assisted workflow componentsEnd-to-end testing of orchestration, contracts, and recovery pathsThis is asenior hands-on engineering role . We expectclear technical judgment, strong ownership, and pragmatic architectural decision-makingwithout unnecessary complexity.ResponsibilitiesDesign, implement, and maintainproduction-grade Python services and runtime componentsOwn complex backend featuresend to end , from domain modeling through rollout and regression coverageBuild and evolvestateful workflow systems, orchestration layers, and asynchronous processingIntegrate with third-party APIs and external service providers in areliable, observable, and fault-tolerant wayImprove system correctness aroundretries, idempotency, error handling, and distributed state transitionsContribute across the stack includingAPIs, integrations, contracts, and toolingWritehigh-signal testscovering unit, integration, contract, and recovery scenariosReview code rigorously and raise the bar fordesign clarity, maintainability, and runtime safetyCollaborate with stakeholders to turnambiguous requirements into robust implementation plansWorking Style We value engineers who are:rigorouspragmaticcomfortable with ownershipconcise in communicationcapable of handling both systems thinking and implementation detailIf you are strongest only inisolated backend CRUD developmentand do not enjoystateful systems, integrations, or workflow complexity , this role is likely not the right fit.RestrictionsTelecommuting is OKNo Agencies PleaseRequirements Required Experience6+ years of professional Python development experienceStrong experience withmodern Python backend development , includingtype-aware design and asynchronous programmingStrong experience designing and maintainingAPIs and service boundariesSolid experience withRedis or comparable key-value/data-structure storesin production systemsExperience withevent-driven or workflow-oriented systems , including retries, resumability, and state transitionsExperience integrating withexternal services, callbacks/webhooks, and long-running remote processesStrong testing discipline with pytest and a clear understanding ofregression preventionComfortable working in systems that mixdeterministic application logic with AI/LLM-assisted componentsAbility to work acrossbackend, platform, and integration concernswithout narrow specializationPreferred ExperienceExperience withFastAPI, Starlette, or similar Python web frameworksExperience withconversational systems, messaging backends, or multi-channel product flowsExperience withqueue-like async coordination patterns, webhook security, and idempotent callback handlingExperience withlocalization/i18n pipelines and user-facing workflow systemsExperience withDocker-based local development and production deployment workflowsExperience working in codebases withstrong architectural boundaries, typed domain contracts, and documentation-driven developmentTechnical Profile The right candidate should be comfortable with most of the following:PythonAsync I/O and coroutine-based service designFastAPI-style API developmentRedis-backed application statePytest-based automated testingREST/webhook integrationsState machines, orchestration, and workflow enginesPayload/schema design and validationProduction debugging and operational reasoningDocker-based development environmentsWhat Good Looks LikeProduces code that isclear, defensible, and easy to evolveUnderstandsfailure modes before they happenand designs accordinglyMakesdeliberate tradeoffsinstead of defaulting to abstraction or framework-heavy solutionsCan move betweenarchitecture, implementation, and debuggingwithout losing precisionWrites tests that reflectreal system behavior , not just happy-path implementation detailsCommunicatesdirectly and professionallywith strong technical judgmentSeniority Expectations This role is not limited to ticket execution.
