Job description

Mission:

We are looking for a highly skilled Software Developer to help design, build, and evolve TEKEVER’s Ground Control System — the core software that plans, monitors, and controls our unmanned aircraft missions.

In this role, you will contribute across different GCS initiatives depending on business needs, from real-time flight systems to mission tooling, payload control, comms/messaging, and operator workflows. You will also play a key role in our transition towards an agentic development approach, enabling more autonomy, automation, and AI-assisted engineering across the team.

This role is ideal for someone who thrives in complex technical environments, values high ownership, and wants to help shape the future of a mission-critical product used globally.

What You’ll Do:

1. Technical Ownership & Delivery

• Design, build, and maintain backend components of the Ground Control System using C#/.NET.

• Implement robust real-time systems that manage telemetry, mission planning, payload operations, and operator workflows.

• Improve performance, reliability, and scalability across different modules of the GCS codebase.

• Contribute to modernizing architecture, tools, and engineering practices as the system evolves.

2. Architecture & System Design

• Design APIs, messaging flows, asynchronous pipelines, and multi-threaded components for high-reliability environments.

• Contribute to architectural decisions around modularity, data flows, error-handling, and system decomposition.

• Work with classification systems, message processors, payload interfaces, and complex stateful components.

• Help shape architectural direction in collaboration with software architects and product owners.

3. Agentic Development & Automation

As part of TEKEVER’s agentic engineering roadmap, you will:

• Use AI/LLM-based tools to accelerate development, refactoring, documentation, and testing.

• Support the design of internal autonomous agents that assist with coding, validation, CI/CD, and documentation.

• Promote automation and tooling that reduces manual effort and increases engineering leverage.

• Help define safe, reviewable, and high-quality AI-assisted workflows for the team.

4. Quality, Reliability & Operations

• Ensure high-quality code through strong testing strategies, clean patterns, and consistent documentation.

• Analyse complex performance and concurrency issues, especially in real-time data environments.

• Improve system observability through structured logging, instrumentation, and monitoring.

• Collaborate with DevOps and QA to ensure smooth delivery pipelines and reproducible builds.

What We’re Looking For:

Experience

• 2+ years of professional software development experience.

• Background in C# and .NET (Framework and/or .NET 6+).

• Experience building real-time, high-availability, or mission-critical systems.

• Experience with large desktop or client applications (WPF experience is a plus).

Technical Skills

• Proficiency in C#, async programming, multi-threading, and memory management.

• Experience designing APIs, distributed systems, or event-driven workflows.

• Familiarity with: Messaging systems (RabbitMQ, Kafka, etc.); Docker / containerisation; CI/CD tooling (GitLab, GitHub, Jenkins, etc.); Observability stacks (ELK, Graylog, Prometheus, Grafana); Data streaming or real-time telemetry

• Experience with WPF/MVVM or desktop application architecture is an advantage.

Mindset & Soft Skills

• Strong sense of ownership and engineering autonomy.

• Ability to navigate ambiguity and contribute to architectural decisions.

• Excellent debugging, problem-solving, and system-design thinking.

• Strong communication skills and collaborative mindset.

• Enthusiasm for automation, AI-assisted development, and continuous improvement.

Why Join TEKEVER GCS

• Work on software that powers real UAV operations around the world.

• Influence architecture, tooling, and engineering practices across the GCS product line.

• Help drive TEKEVER’s transition to agentic engineering and AI-assisted development.

• Join a team that values autonomy, collaboration, and technical excellence.

• Contribute to meaningful, high-impact missions across maritime, defence, and civil applications.
