Senior Backend Engineer

Own the Engineering. Make the Scheduling Magic happen.

Doodle is a B2B SaaS platform used by millions of professionals to coordinate meetings and collaboration across teams and companies. We are expanding from a scheduling product into a broader productivity and coordination platform, which creates meaningful technical challenges at scale.

We aren’t just looking for someone to "write code." We need a Systems Builder. Someone who gets excited by the precision of reactive programming, the complexity of event-driven architectures, and the unique edge cases that arise when processing time across every global time zone simultaneously.

What You’ll Actually Do

• Own the Backend: Design and ship high-performance services in Go and Java that serve millions of global users.
• Wrangle "Time": Tackle the fascinating logic behind global scheduling—where millisecond precision meets complex human variables.
• Scale High: Optimize our core platforms for massive concurrency and global distribution.
• Lead the Standard: Champion clean code and CI/CD excellence in an environment that values "doing it right" over "doing it fast."

What do you bring?

You’ll thrive here if you are a Senior who values customer impact as much as elegant syntax.

• The Foundation: You have a deep grasp of DS/Algo and distributed systems.
• The Toolkit: You are a pro in Go and/or Java and have experience shipping production-ready backend services.
• The Mindset: You think in Events. You understand Kafka, reactive systems, and how to build for scale.
• The Bonus: If you’ve danced with Kubernetes, Docker, or AWS, you’ll feel right at home.
• The Location: You are based in Poland with full work authorization (we cannot provide sponsorship at this time).

Why Doodle?

• Real Impact: Your commits will change how the world meets.
• Technical Stretch: We deal with "Time" problems most companies never encounter. It’s a masterclass in distributed logic.

Culture of Trust: We value curiosity, autonomy, and a life-work balance that respects your time as much as our users'.
