Top Software Engineer Jobs in Berlin

The Senior Software Engineer will design and develop high-quality web and mobile applications, ensuring code quality while collaborating with product teams and mentoring junior engineers.

Design and implement core cloud platform services, control-plane components, and internal APIs. Build platform abstractions and production-grade Go tooling, drive architectural initiatives (gRPC, eventing, cluster-api), improve scalability and developer experience, and support production incidents when needed.

Work on YDB distributed storage and database systems to maximize performance on modern and legacy hardware (NVMe, HDD, DPUs). Reengineer components for low-latency, high-throughput workloads, profile and debug production systems, and design resilient distributed storage primitives. Collaborate on incident resolution and production deployments to support Nebius cloud services.

Build and maintain a distributed, fault-tolerant, high-performance block and filesystem storage system. Work on virtualization (virtio-blk, virtio-fs, QEMU, vhost-user), high-throughput VM-to-storage networking (TCP, RoCEv2/RDMA), and core storage features like replication, consensus, self-healing, and data migration. Debug and optimize performance-critical I/O paths while writing reliable, maintainable code in a collaborative team environment.

Own and evolve a custom Chromium fork to evade anti-bot detection, reverse-engineer JavaScript challenges, build automated tooling and pipelines for evasion, develop observability for fingerprint mismatches, and mentor engineering on browser internals and stealth techniques.

Lead analysis and resolution of system performance issues across Akamai's distributed Linux platform. Design and implement scalable software and tools for performance detection, mentor engineers, and collaborate across teams to deploy efficient solutions.

Build foundational agent infrastructure for LLM-driven developer assistant: orchestration, tool execution, context management, evaluation, and trust/permissions. Ship reliable, observable backend systems, own core infra, participate in on-call, and mentor peers while launching agentic features to customers.

Design and implement privacy-enhancing, anti-tracking features and data sanitization in Firefox. Improve Gecko architecture, write performant C++, JavaScript, and Rust code, and deliver complex features on tight release schedules while collaborating asynchronously with a distributed team.

Design, build, ship, and own end-to-end product features across frontend, backend, and data. Translate ambiguous product requirements into reliable, well-tested systems; deploy, monitor, and maintain production services; participate in design and architecture, code reviews, and mentor peers while working closely with product and design teams.

Develop and maintain scalable backend services using Graph features; optimize systems performance and security; mentor team members; ensure compliance and quality standards.

Join the Kubernetes product team to design and implement Kubernetes operators and addons, write high-quality Golang and Python code, debug issues, collaborate with a distributed team, mentor colleagues, and contribute to open-source integration and lifecycle management. Travel 2–4 weeks yearly for team events.

Own QA operations and release quality for civil engineering software. Collaborate with scrum teams to run manual and automated tests, design and maintain test cases, report and track defects, reproduce customer issues, automate dashboards/APIs, and improve testing processes to reduce product quality risk.

Design, build, operate, and support resilient distributed platform services. Write maintainable code, troubleshoot production issues, improve reliability and observability, and assist internal teams. Participate in on-call rotations and collaborate on platform evolution.

Lead design and implementation of 2D/3D web graphics features and frontend components for an embedded web viewer. Develop a cross-platform graphics engine, evaluate new technologies, leverage AI-assisted development tools, and collaborate with architects, product managers, and distributed engineering teams to deliver performant visualization and collaboration features.

Be the first full-time frontend engineer owning and scaling the platform frontend: transition codebase from contractor, design and ship features, ensure performance, accessibility and scalable frontend architecture, collaborate on API/backend integration, and leverage AI tools to accelerate development.

As a Senior Software Engineer, you'll design secure backend systems, uphold engineering excellence, ensure operational reliability, and guide architectural decisions within a core product team.

Design, build, and operate production-grade generative AI systems: multi-agent orchestration, end-to-end RAG pipelines, LLM evaluation and integration, scalable AWS-based AI infrastructure, CI/CD for models, observability, data validation, and evaluation frameworks to ensure quality, attribution, and resilience.

Design and build scalable RL post-training infrastructure spanning single-GPU experimentation to multi-thousand-node production. Optimize training-inference-rollout loops across GPUs/CPUs/LPUs, improve open-source RL frameworks, ensure fault tolerance, elastic scaling, fast restarts, and collaborate with hardware, networking, and compiler teams to enable high-performance RL workloads.

Design, build, and operate backend services and LLM orchestration pipelines. Implement RAG/agent flows, CI/CD, schema migrations, observability, secure multi-tenant access, and participate in on-call incident response to ensure reliable production systems.

Own, design, and develop the AI Data Platform: maintain a high-scale data product platform (≈400K pipeline jobs/month, petabyte scale), architect cross-cloud data infrastructure, build and operate automated data pipelines, ensure data observability and quality, and implement AI-driven features and AI data agents to expose AI-ready data products.

Responsible for developing and optimizing NVIDIA's AI platform, especially using JAX. Involves designing core components, collaborating with researchers, and enhancing efficiency in AI solutions.

The role improves Firefox development workflows, mentoring team members, collaborating for code review, and using data to identify trends.

As a Principal Software Engineer at Autodesk, you will shape technical direction, solve complex design automation challenges, and collaborate with cross-functional teams to deliver user-facing products. You'll work hands-on with cloud-based systems and drive architectural decisions, contributing to sustainable solutions in design.

The Senior Backend Developer will build Ruby on Rails services, research Slack & MS Teams ecosystems, and support continuous improvement within the Workato platform.

The Senior Software Engineer will design and develop features using TypeScript and Node.js, contribute to API infrastructure, build AI-powered features, and collaborate across teams to improve quality and performance.
