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 general 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 Germany 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
