About the role

StrikeWeb is Delian's real-time command and control platform for autonomous systems, delivering operational insight and coordination across a fleet of robotics agents in critical national security and defense applications. As a Senior Backend Engineer, you'll design and build the robust and scalable infrastructure that enables high-throughput data processing, real-time decision pipelines, and seamless integration across sensors and actuators.

This is a mission-driven engineering role ideal for engineers who are motivated by building scalable, reliable and impactful production-critical systems.

In this role you will get to

  • Design and develop scalable backend services that integrate and process real-time sensor data across distributed systems.

  • Build core infrastructure and deployment pipelines to support continuous delivery of StrikeWeb capabilities to production.

  • Develop testing frameworks for validating backend logic in both software-only and hardware-in-the-loop environments.

  • Benchmark application performance under load and drive systemic optimizations in latency, throughput, and resiliency.

  • Collaborate cross-functionally with frontend, robotics, DevOps, and product teams to deliver end-to-end capabilities from concept to field deployment.

What previous experience would make you successful in this job (In our view, but feel free to prove us wrong)

  • A degree in engineering or similar field.

  • A track record of building, deploying and maintaining software driven solutions to actual users.

  • 5+ years of backend development experience, including building and deploying production-grade scalable services.

  • Strong understanding of distributed systems, networking fundamentals, and real-time or near-real-time application architectures.

  • Proficiency in one or more backend programming languages such as Python, Go, Rust, Java, or C++ and deep understanding of their respective ecosystems.

  • Experience with API design for control systems and event-driven architectures (e.g., gRPC, Kafka, MQTT).

  • Experience working with cloud platforms (e.g., AWS, Azure, GCP) and cloud-native services for compute, storage, and messaging.

  • Experience with CI/CD pipelines and modern build/deployment toolchains (e.g., GitHub Actions, Docker, Terraform).

  • Experience integrating with and/or building telemetry, monitoring, and alerting stacks (e.g., Prometheus, Grafana, ELK, OpenTelemetry).

  • Experience with robotics systems, embedded software, or high-throughput sensor data processing.

  • Experience with high-performance networking, stream processing frameworks, and/or time-series databases.

  • Background in security-focused or defense-related backend systems with reliability and auditability requirements.

  • Contributions to open-source backend frameworks, infrastructure tools, and/or monitoring systems.
