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.

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.
