Team Lead IoT & Data Platform (m/f/d)

At STABL Energy, we are building modular battery systems that rethink how energy storage is deployed and scaled. Our cloud platform connects, monitors, and operates these systems in the field — forming the digital backbone of our products.

As Team Lead, you take end-to-end ownership of STABL’s Battery Cloud — the platform that connects our fleet of battery systems, processes real-time telemetry, and enables operational excellence through internal tools and customer-facing services.

You will lead a small but highly capable team (currently 2 engineers) and remain technically hands-on. This is a startup leadership role: you set direction, make architectural decisions, and contribute directly to implementation.

You operate at the intersection of IoT, distributed systems, and product engineering — bridging embedded edge devices, AWS infrastructure, and user-facing applications.

You are accountable for the architecture, reliability, and scalability of our cloud platform.

This includes:

• Defining and evolving the overall cloud architecture (IoT connectivity, data ingestion, storage, APIs, portal)

• Ensuring reliable and secure connectivity of our BESS fleet in the field

• Designing scalable telemetry pipelines and time-series data infrastructure

• Owning observability, uptime, and operational robustness

• Leading the development of our internal service and operational tools

• Establishing engineering standards for cloud development, deployment, and cost efficiency

• Hiring, mentoring, and structuring the Cloud team as we grow

• Aligning technical decisions with product, firmware, service, and compliance stakeholders

• Proven experience leading engineering teams in a startup or fast-moving product environment

• Strong background in designing and operating distributed systems in AWS cloud environments

• Experience with IoT architectures and device connectivity at scale

• Solid understanding of data pipelines, time-series storage, and API design

• Hands-on proficiency in modern backend development using TypeScript and Python

• Experience with infrastructure as code using CDKTF

• Ability to switch between strategic thinking and hands-on implementation

• Strong communication skills and ability to work across firmware, hardware, operations, and compliance teams

• Experience in energy systems or industrial IoT is a strong plus.

• Agile, open & innovation-driven culture with flat hierarchies, quick decision-making processes and real ownership
• Company pension scheme to support you plan for the future
• Flexible working hours, a hybrid work model, and the option to work remotely from abroad
• Digital meal vouchers with Circula Lunch - enjoy tasty lunches on us!
• Monthly benefit in kind to spend at your favourite stores
• Corporate benefits portal with exclusive employee discounts
• Regular team-building activities and team events
