Software Developer - Ground Control System (GCS)

TEKEVER

Caldas da Rainha, Portugal

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:

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.

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.

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.

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.
