To strive for this we combine expertise in autonomy, electronic warfare and rapid manufacturing. Paired with young, passionate and mission driven engineering and technical talent.

We have offices in London & Athens.

About The Role

StrikeWeb is Delian’s mission-critical platform for commanding and controlling autonomous systems deployed across complex, real-world environments. As a Backend Engineer, you will help build the high-performance services that power data ingestion, situational awareness, and decision-making for national security and defense operations.

This is a unique opportunity to contribute to real-world robotics infrastructure at scale, with rapid iteration cycles and a direct line from code to deployment.

In this role you will get to

• Develop and maintain core backend services that integrate real-time sensor and telemetry data for fielded autonomous systems.
• Build scalable, cloud-native APIs and systems that support real-time workflows and high-throughput processing.
• Create automated deployment and integration pipelines to support a continuously evolving service ecosystem.
• Collaborate with frontend, DevOps, and robotics engineers to ensure seamless data flow and system reliability.
• Contribute to testing and benchmarking systems to validate performance and robustness under real-world conditions.
  
  

Must have experience

• 3+ years of experience developing and deploying production backend systems.
• Solid programming skills in one or more languages such as Python, Go, Rust, C++, or Java.
• Strong understanding of web application architecture, backend frameworks, and networked systems.
• Experience working with cloud platforms (e.g., AWS, Azure, or GCP) and containerized environments.
• Familiarity with CI/CD pipelines and version-controlled workflows (e.g., GitHub, GitLab).
• Exposure to monitoring and logging tools such as Prometheus, Grafana, or ELK.
  
  

Nice to have experience

• Experience with real-time data processing or telemetry-driven systems.
• Familiarity with messaging systems or streaming technologies (e.g., Kafka, MQTT, WebSockets).
• Background in robotics, simulation, or embedded systems integration.
• Understanding of API design principles (REST, gRPC) and backend service security.
• Involvement in infrastructure performance tuning or observability improvements.
