We had built other successful businesses together. We’d built unsuccessful some too and learned a ton from that.We're backed by fantastic investors (MOC, Peak, Kogito, SMOK) and advisors, including domain experts from companies such as PayU, Piwik PRO, and Your KAYA. We've just raised our seed round. In other words, we have all the resources needed to be able to focus on building the product, shipping fast, and delivering value to the clients.In other words, we have all the resources needed to be able to focus on building the product.The role: Fullstack engineerWhy this roleWe recognize software engineers as creators who can build something remarkable. We're looking for an ambitious individual who will help us build Juo — by being a co-creator, not only an executor. We don't put ourselves into any box or "stack".

We're looking for an obsessive builder and a curious problem-solver, who knows how to ask the right questions and where to find answers for them. We work with many technologies that work for us best, so you should be open to getting to know new ones if such a need arises.The team's structure is flat, and thus we always seek people who think long-term. We want to work only with those who are not driven by opportunism. We take both product development and relationship building equally seriously.Business-wise, we have passed the most difficult stage for any startup — finding the so-called product-market fit, which means we can focus on building and perfecting the product without financial concerns about the purpose of these actions. We are confident in ourselves, in what we do, and in the value we create for ourselves, our clients, and end users.Responsibilities:Building a new major iteration of the product with high extensibility and great developer experience in mindDeveloping new features and iteratively improving existing onesFinding, investigating, and fixing bugs and performance issuesSupporting customers when the above occurs (customer-driven development)Discussing ideas, solutions and technologies with the teamProactively coming up with ideas for development and product improvementsRequirements and qualifications:Experience with TypeScript, SQL databases, JS frontend frameworks, and automated testingBroad knowledge of other web technologies and their nuancesTerminal is your best friendBeing able to discuss technical matters with other team membersAbility to work closely with your teammates (product, design, and growth)Comfort with working in a lean startup wayKeeping an open mind when learning new technologiesOverall ability to learn quicklyFluent Polish (written and spoken)Fluent technical and documentation EnglishIntermediate+ English (written and spoken)At least 5 years of experienceExperience with tech stack and tools below or similarTechBackend:Modular Fastify server in TypeScriptState persitance in Managed Postgresql databaseCritical and periodic tasks processed in dedicated BullMQ workers with Redis storageStrong I/O validation with JSON schemas generated with TypeBox with automatic OpenAPI schema generationFrontend:Multiple Vue front-ends in TypeScriptContext/Provider pattern for state propagationShared UI components with Storybook integrationAutomatically generated SDKs shared between front-endsInfrastructure and tools:Managed Kubernetes provisioned with HelmfileFull CI/CD on GitHub actionsData streamed through SegmentObservability via Prometheus and SentryCommunication over Slack, Linear and NotionWhat we offerBuilding an extraordinary team is a fantastic challenge.
