Software Engineer, Backend (Java) - All Genders

Software Engineer, Backend (Java) - All Genders

We usually respond within two weeks.

Doodle is a B2B Saa S platform used by millions of professionals to coordinate meetings and collaboration across teams and companies.

We are building the future of scheduling and productivity, working at the intersection of human collaboration and digital efficiency.

We craft elegant solutions to complex problems and seek passionate problem solvers who share this drive.

You are more than a coder.

You are a proactive builder and continuous learner who thrives on shipping products that matter.

You always find a way to reach the goal and go beyond the surface to solve big challenges.

Our core backend is built on Go and Java services running on Kafka, designed for high throughput.

We value engineers who are naturally curious and proactive, who read, trace, and understand workflows across the entire codebase and look beyond their primary language to solve complex problems.

We love high velocity and encourage the use of LLM and agentic tools (Specs, Loops, and agentic workflows) to iterate fast and build systems.

We pair this speed with deep pride in ownership, maintaining a “READ THE CODE” mindset with full accountability for every line you deliver.

• What You'll Actually Do
• Own the Backend: Design, build, and deploy robust, scalable, high‑performance backend services in Java that power our core platform.
• Serve the Data: Expose backend endpoints through Graph QL, with efficient data fetching, query optimisation, and clean integration with frontend systems.
• Architect for Scale: Build event‑driven solutions on Kafka for seamless data flow, system reactivity, and extreme reliability.
• See the Whole System: Keep full visibility across the backend ecosystem and understand how services integrate across our distributed infrastructure.
• Ship with AI: Use LLM and agentic tools to move fast while retaining total ownership and full understanding of the generated code.
• Solve Time: Tackle the hard challenges around how Time is managed, processed, and presented across the globe.
• Translate the Hard Stuff: Work closely with cross‑functional teams to turn complex scheduling requirements into clean, elegant technical solutions.

What do you bring?

• You thrive here if you are a builder who values customer impact as much as clean systems.
• Foundation: A Bachelor’s in Computer Science, a related technical field, or equal practical experience.
• Toolkit: Professional experience designing, developing, and shipping production‑ready, highly concurrent backend services in Java.
• The Systems Mind: Strong systems‑level thinking, with the ability to read, debug, and understand multi‑language codebases.
• The Distributed Layer: Practical experience with distributed systems, microservices, and event‑driven architectures built on Kafka.
• Nice to have
• The AI Edge: Advanced experience using modern AI‑assisted engineering workflows (Specs, Loops, agentic tools) to safely speed up backend testing, generation, and architecture validation.
• The Infra: Deep knowledge of reactive programming models, cloud infrastructure (AWS or GCP), and containerisation (Docker, Kubernetes).
• The Fundamentals: A strong foundation in computer science fundamentals—data structures, algorithms, and distributed system design.
• The API Layer: Experience designing and serving APIs, ideally Graph QL.
• The Location: You are based in Germany with full right to work. We cannot sponsor visas or support relocation at this time.

Why Doodle?

• Real Impact: Your commits change how the world meets.
• Technical Stretch: We deal with “Time” problems most companies never meet, focusing on high throughput, distributed, and reactive systems.
