Join our client's large international organisation active in the energy sector, contributing to real-time energy management & balancing and solutions supporting the energy transition. You will work on real-time software products that help balance the electric grid and connect physical assets (e.g., batteries, renewable parks) to forecasters and optimizers to improve optimisation results.

You will join a context where software teams analyse, design, develop, maintain and support products focused on real-time services, including low-latency streaming and dispatching components.

YOUR TASKS

As Senior Software Developer and Architect, you will:

Provide technical guidance to development (team of 3–5 people).

Provide user assistance and support.
Monitor systems and provide L2 support, incident resolution and troubleshooting (root causes of recurring incidents).

YOUR SKILLS AND EXPERIENCE

Must-have

6+ years of software engineering with technical design and architecture responsibilities.
Strong capability for technical / complex analysis (components include complex technical features).
Proficiency in .NET.
Proficiency in Python, including async programming and performance-oriented design.
Proven experience designing and operating event-driven architectures (Kafka, Azure Event Hub, or MQTT).
Strong understanding of distributed systems concepts (scalability, fault tolerance, backpressure, ordering, idempotency).
Hands-on experience with Kubernetes in production (deployments, autoscaling).
Experience with Redis (stateful systems / caching use cases).
Strong testing culture: unit tests, integration tests, production validation.
Production-grade observability: metrics, logging, alerting (e.g., Grafana, Prometheus, or equivalent).
Familiarity with Agile development practices.

Nice-to-have / stack exposure (plus)

Azure and Infrastructure as Code (e.g., Bicep).
Familiarity with parts of the stack: AKS, Azure Functions, Azure Service Bus, PostgreSQL, Azure Data Explorer, GitHub Actions / CI/CD.
Experience with Scala or Rust is a plus.
Polytechnic engineering Master’s degree (or equivalent) is a strong plus.

EXTRA INFORMATION

Location: Brussels, Belgium (relocation mandatory if living far / or ability to commute regularly)
Work model: Hybrid - 2 days onsite / 3 days remote
Preferred start date: 02/03/2026
Contract duration: 1 year, extendable for 2 more years (max 3 years)
Contract type: Freelance
Languages: English fluent, French or Dutch is a plus
