Job Description

Senior Fullstack Developer – Backend

Capgemini

• Deliver integrated concept demonstrations for USV workflows such as mission execution monitoring, route execution support, vehicle health/status, operator oversight, and simulation-backed demonstrations. • Connect backend services to simulation, replay, and vessel-adjacent systems so concepts reflect realistic telemetry cadence, state transitions, faults, and mission events. • Support end-to-end integration across services, data streams, and mission software components. • Develop Python services, adapters, and tooling to support concept development, data translation, automation, replay, and simulation hooks. • Implement and maintain real-time interfaces such as REST APIs, WebSockets, TCP/UDP communication paths, streaming pipelines, and pub/sub patterns. • Design and troubleshoot inter-service communication, connection management, reconnection behavior, message routing, and high-rate telemetry handling. • Work within distributed architectures common to autonomy stacks, including Redis or Valkey, DDS, pub/sub buses, and other message-oriented systems. • Diagnose backend and networking issues such as service discovery failures, QoS/config mismatches, dropped connections, environment drift, and runtime logging problems. • Contribute to or interface with C++ components where performance, hardware interaction, protocol handling, or existing subsystem integration requires it. • Work across mixed-language systems where Python services integrate with C++ libraries, binaries, or networked components. • Assist with protocol and device integration efforts relevant to autonomy or vehicle systems. • Support frontend or operator-facing application work as needed, including integration with existing web interfaces.

Job Requirements

  • BS in Computer Science, Computer Engineering, Software Engineering, or equivalent professional experience.
  • Strong Python experience for backend services, tooling, networking, or automation.
  • Experience with backend system design and real-time integration patterns such as WebSockets, REST, TCP/UDP, streaming, or pub/sub.
  • Working knowledge of C++ for software integration, systems work, or performance-sensitive components.
  • Experience with Docker and Docker Compose; familiarity with Kubernetes is a plus.
  • Strong debugging skills across backend services, networking behavior, and distributed systems.
  • Ability to work across multiple layers of a software stack in support of integrated concepts and demonstrations.

Benefits

  • Paid Time Off
  • Paid Company Holidays
  • Medical, Dental & Vision Insurance
  • Optional HSA and FSA
  • Base and Voluntary Life Insurance
  • Short Term & Long-Term Disability Insurance
