## About the Role

* 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).

## Description

* 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.
