Lead .NET Software Engineer - Azure & Integration

About Brainsquare

Brainsquare develops software and integration solutions that help organizations connect their systems and support their business operations. You will work with engineers, technical leads and solution architects in an international delivery environment.

Your mission

We are looking for a Lead .NET Software Engineer to strengthen the integration team supporting a major service transformation program in a global manufacturing environment.

The program brings service-related processes into a Microsoft Dynamics environment and connects this platform with enterprise applications supporting production, distribution and sales. Reliable API’s and messaging flows are essential to keeping these systems aligned.

Based in Belgium, you will combine hands-on engineering with day-to-day technical leadership of two remote Software Engineers. You will help the team maintain a steady sprint rhythm, review code, resolve technical blockers and deliver integration components that meet demanding performance and reliability requirements.

System architecture and overall solution design remain with the core architecture team. Your focus will be on translating that direction into well-engineered, production-ready software and consistent team delivery.

Key responsibilities

• Coordinate the day-to-day technical work of two remote Software Engineers, ensuring clear task allocation and steady progress toward sprint objectives.

• Contribute production code using C#, .NET 10 and Azure Function Apps.

• Perform detailed code reviews, checking code quality, performance and alignment with agreed designs and engineering standards.

• Ensure integration components meet requirements for latency, throughput, scalability, resilience and fault tolerance.

• Identify and resolve technical blockers, supporting team members with practical guidance and hands-on problem-solving.

• Translate architectural specifications into actionable implementation work and clarify technical questions with the core architecture team.

• Act as the operational link between the architecture team and the remote engineering team.

• Mentor team members and strengthen shared engineering practices across the team.

What makes this role interesting?

• A technical leadership position that keeps you actively involved in software engineering.

• Integration challenges involving high-volume messaging and business-critical enterprise systems.

• An Azure-native environment using modern .NET and serverless technologies.

• Close collaboration with solution architects and an international engineering team.

• Direct influence on code quality, delivery effectiveness and the reliability of software supporting service operations.

Location

Applicants must currently reside in Belgium and be legally authorized to work in Belgium. This position is based in Antwerp.
