Senior SWE - B2B SaaS I Berlin

_We are digitalising one of Europe’s largest and most heavily regulated industries._ _The packaging industry has a market volume of several hundred billion euros and is under enormous pressure to act due to new regulations such as PPWR, EPR and EUDR._ _With **Packa**, we have built the first end-to-end SaaS platform for intelligent packaging management – in high demand, well-funded and growing fast._ **What you can expact at Packa** * **Creative freedom:** You work directly with Packa’s leadership team – with real impact from day one. * **Ownership:** You’ll be part of a highly motivated, diverse and successful team with a high degree of freedom and responsibility from the start. * **Hybrid work:** You work from a great office in Berlin-Prenzlauer Berg. * **Leadership:** You work in a company with an inspiring vision, led by an experienced founding team and backed by leading investors. * **Recognition and commitment:** We believe in fair compensation and offer a clear growth path with real development opportunities. **Your responsibilities** * You actively contribute to the technical evolution of our platform and bring in your own ideas on how to make our product more robust, performant, and scalable. * You take part in technical design decisions – from the architecture of individual features to cross-cutting topics such as data models, API design, or tooling. * You work closely with Product, Design, and Business stakeholders to shape technical solutions around user needs – and you're not afraid to challenge the original requirement when you see a better way. * You work in a structured and self-directed manner: from task breakdown through implementation to deployment and monitoring in production. Code reviews, testing, and clean documentation are a given for you. * You collaborate closely with Senior Engineers and the Tech Lead and grow technically along the way – through pair programming, joint architecture sessions, and honest, constructive feedback. **What you bring** * You have up from 5/6 years of experience in software development – ideally in a scaling SaaS environment where you've not only built features but also supported them live in production. * You have solid skills in TypeScript and Node.js, ideally with NestJS on the backend – complemented by a good understanding of modern frontend technologies such as React. * You've already gained experience in building modern APIs, working with different system architectures, and data modeling – and you can weigh trade-offs between different approaches. * You're familiar with deployment, testing, and CI/CD processes and see them as an integral part of development, not an afterthought. * You know your strengths, apply them deliberately – and actively ask for support when it makes sense, instead of getting stuck. * You work in a solution-oriented, pragmatic way and stay close to the product vision: you ask "why" behind a requirement before jumping to "how". * You speak English fluently – German is a plus.
