Software Engineer: Tech Lead (f/m/d)

Even great products require remarkable presentations to win on the digital shelf. CELUM solves this challenge with its unique SaaS Content Supply Chain Management Platform. CELUM’s software enables Marketing, Brand and Product teams to build engaging experiences through creating, approving, managing, and distributing content to every required channel, and to understand the content’s impact. - we make content work!

You’ll be the person who turns “this would be great for customers” into “it’s live, it’s reliable, and we can iterate fast.” This role is product-first.

Here’s what you’ll take ownership of in this role:

• Lead technical execution for a product area across discovery, delivery, and iteration.
• Translate product requirements into scalable, maintainable implementations.
• Drive engineering standards around reviews, testing strategy, performance, security, and reliability.
• Mentor engineers through feedback, pairing, and practical guidance.
