We are one of the fastest growing B2B scale‑ups in Germany, creating real value for the engineering industry.

With our software, we are setting a new standard in the spare parts business, enabling comprehensive market transparency for the first time.

To achieve this, we challenge the status quo every day and support our employees in actively shaping their careers and pushing their own boundaries.

Become part of a team that can't be stopped, that overcomes challenges together and celebrates success together.

• Be part of our success story! Your Mission
• Collaborate with product developers, engineers and internal stakeholders to break down roadmap items into well‑defined, executable tasks.
• Direct, constrain and verify the output of AI coding agents - ensuring correctness, quality and alignment with system architecture and business requirements.
• Design and build scalable, resilient software for enterprise customers that operates reliably 24/7 as a mission‑critical system.
• Own quality end‑to‑end: think about correctness before implementation, define what should be tested and at which level, and make failures observable and diagnosable.
• Communicate clearly across technical and non‑technical contexts - translating between high‑level business intent and concrete engineering decisions.
• Identify risks early, raise concerns constructively and move work forward without waiting for perfect information.
• Design systems that are understandable and adaptable, considering how software behaves in production, how it will fail, and how it can be safely changed.
• Your Skills
• Proven track record as a Senior Software Engineer in a B2B Saa S, enterprise software or similarly reliability‑critical environment.
• Strong conceptual understanding of web application architecture - APIs, data models, distributed systems, security, observability and deployment - technology‑agnostic and able to reason at the right level of abstraction.
• Excellent communicator in English (near‑native level): you explain complex topics clearly, listen actively and collaborate constructively with engineers, product developers and non‑technical stakeholders alike.
• Self‑motivated and curious: you investigate problems independently, identify risks proactively and move things forward without needing every next step defined for you.
• Pragmatic, not dogmatic: you apply engineering principles to the actual context, distinguish necessary quality from unnecessary complexity and ship things that work - reliably.
• Confident working with AI tools as a multiplier of your own capacity, while maintaining full accountability for what you deliver and a critical eye on AI‑generated output.
• Comfortable with ambiguity and change: you design for evolution, not for a fixed specification, and you thrive in a fast‑moving scale‑up environment where things shift quickly.
• Background in start‑up or scale‑up environments is a strong plus; domain knowledge in manufacturing or pricing is not required.
• Our Tech Stack
• Type Script, Angular, Prime NG, Jasmine, Cypress, REST, Java, Kotlin, Postgre SQL, Mongo DB, AWS, Azure, Kubernetes, Docker, Git, CI / CD
• Your Benefits
• Our modern and open scale‑up culture gives you the freedom to unleash your creativity within a dynamic and agile team.
• Fail Fast, Learn Faster: Feedback here is exactly what it should be - an essential part of your work.
• We invest in your growth: Discover our Learning & Development programs - including an L&D budget!
• Flexible working hours and the option to work hybrid.
• Rest is important too - 30 days of vacation.
• Travel by Train: Even MARKT‑PILOTS take the train! We subsidize your monthly Deutschland‑Ticket!

• Job bikes for those who prefer to travel on two wheels!

• Crew‑Love: Look forward to regular team events, exciting gaming sessions, and much more.
• Stay Healthy: With a discounted WELLPASS membership and healthy snacks, you can always recharge your batteries.
• Corporate Benefits: Discover a variety of attractive offers from top brands with exclusive discounts.
