Senior Software Engineer (w/m/d) - B2B Saas I Berlin (hybrid)

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.

• 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.

• 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.

• 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.
