We are LIFEPOWR! A young and dynamic company, based in Antwerp. We orchestrate over 30’000 distributed energy sources such as batteries, electric vehicle chargers and solar inverters with the purpose of maximizing the value of renewable energy flexibility for users and grid and therefore enabling the success of the energy transition.
We firmly believe that any asset must be able to join the orchestra and take part in a stable and affordable energy system, using renewable energy maximally and rewarding everyone equally good for their investments in renewables.
We stand for sustainability, innovation, and carry high value for ownership and autonomy.

We firmly believe that any asset must be able to join the orchestra and take part in a stable and affordable energy system, using renewable energy maximally and rewarding everyone equally good for their investments in renewables.
We stand for sustainability, innovation, and carry high value for ownership and autonomy.
We are looking for an experienced senior level Backend Engineer - Platform & IoT Integration , who will take ownership of core backend and integration systems across our platform. You combine deep technical skill with a generalist mindset: comfortable moving between application code, cloud infrastructure and device-level integration, and trusted by the team as the person to call when something breaks or a solid architectural decision is needed.
Key Responsibilities
- Own and evolve core backend and billing services end-to-end.
- Design, build and maintain backend services and their AWS deployment pipelines.
- Manage and evolve our timeseries data stack (e.g. QuestDB) that underpins device and energy analytics.
- diagnose and resolve production issues across cloud and device code.
- Support teammates who are blocked on code or infrastructure, and share architectural knowledge across the team.
- Apply solid software design practices (e.g. domain-driven design, microservice patterns) and contribute to version releases across INT/ACC/PROD environments.
What we expect
Soft Skills
- Strong communicator who can explain technical trade-offs clearly to engineers and non-technical stakeholders alike.
- A generalist mindset, comfortable moving between application code, infrastructure and device-level integration rather than staying in one narrow lane.
- High degree of ownership and reliability; you follow through without needing to be chased.
- Comfortable working independently in a fast-moving scale-up environment, and proactive about proposing improvements.
- Open to doing thorough code reviews and sharing knowledge, not just shipping your own work.
- Able to link the dots across systems and communicate clearly when diagnosing what broke and why.
- Willing to support teammates who are blocked, even outside your own area of ownership.
Technical Skills
- Proven experience building backend services (Node.js/TypeScript or comparable) in production.
- Hands-on experience with AWS (e.g. Lambda, CDK) for deploying and operating cloud-native services.
- Experience with timeseries or high-volume data pipelines (e.g. QuestDB, Timestream, InfluxDB or similar).
- Working knowledge of device/IoT integration and data scraping, or a strong willingness to learn it.
- Solid understanding of microservice, API-driven and domain-driven design (DDD).
- Comfortable using observability tooling (e.g. CloudWatch, Sentry) to diagnose issues in production.
- Comfortable using AI tools to support and accelerate technical work.
- Solid grasp of security requirements for cloud and connected devices, and how to actually implement them (secure-by-design APIs, secrets and key management, least-privilege IAM)
- Awareness of the compliance landscape our platform operates in (GDPR, NIS2, CRA) and able to translate current and upcoming obligations into concrete architectural and release decisions.
Nice to have
- Experience in the energy sector (IoT platforms, smart metering, renewables, billing/tariff engines).
- Familiarity with monitoring and error-tracking tools (e.g. Sentry) beyond native cloud logging.
- Familiarity with real-time/distributed database migrations.
- A track record of introducing unit-test coverage into existing codebases.
- Exposure to serverless architecture patterns and infrastructure as code (e.g. AWS CDK).
- Experience with event-driven architectures (Kafka, Kinesis, MQTT, etc.).
- Experience applying domain-driven design (DDD) principles in production services.
- Comfortable contributing to release and deployment coordination across multiple environments (INT/ACC/PROD).
- Experience coordinating hardware/software integration projects (embedded + cloud systems).
What we offer
- Hybrid working and flexible working hours within a young, explorative, and growing company.
- A friendly and dynamic team, united by a shared mission: delivering the best energy management solutions.
- A creative environment where your commercial insights and contributions are highly valued, with room to shape strategies and make an impact.
- The opportunity to quickly take on significant responsibility in a scaling organization.
- A compensation package aligned with your experience, skills, and added value to the company.
