Your role

To combine strong product judgment with deep technical ownership, we are looking for a Senior Software Engineer (f/m/x).

As a Senior Software Engineer, you will own complex features and technical initiatives end-to-end, from understanding the underlying problem and challenging assumptions to designing the solution, shipping it, and improving it in production.

Alongside your work within a product module, you will help solve technical problems that have broader consequences for the platform and the engineers building on it.

At Tanso, senior engineers remain hands-on product builders.

The main difference at senior level is not simply owning "bigger features." It is your ability to go deeper technically, navigate more complex problem spaces, make high-quality architectural decisions, and raise the effectiveness of the engineering organization around you.

Key responsibilities

• Own technically complex product initiatives from problem definition through architecture, implementation, rollout, and iteration.
• Identify unnecessary complexity, challenge assumptions, and help the team focus on solutions that create meaningful customer value.
• Contribute to cross-cutting platform improvements that make the product more reliable, maintainable, and easier to evolve.
• Raise the technical quality bar through thoughtful design, code reviews, technical guidance, and hands-on collaboration with other engineers.
• Work closely with product design, customer success, and other engineers to turn ambiguous problems into effective product solutions.

Your profile

• 5+ years of hands-on Type Script experience in high velocity Saa S environments.
• Strong full-stack and product thinking, understanding systems end-to-end.
• Experience with backend development, ideally with Postgre SQL and Azure.
• Clear, precise communicator in English.
• Self-driven problem solver with strong ownership and execution mindset.
• Nice to have German language skills.

What we offer

• A highly competitive compensation package with an attractive equity package to participate in Tanso's growth.
• Hybrid working model that combines the benefits of onsite collaboration with the flexibility needed.
• A company-contributed pension plan to support long-term financial security.
• Yearly budget to support ongoing professional development.
• Sponsored access to EGYM Wellpass to prioritize your wellbeing with thousands of options.
• Exclusive discounts that help you save on a wide range of everyday brands, services, and experiences.
• Our team

We're a diverse group of people, and that diversity is what makes us great.

We bring unique perspectives to everything we do and are always eager to learn from each other.

We work in cross-functional teams to tackle ambitious challenges, actively seek feedback and be the best versions of ourselves.
