Hardware Engineer (m/f/d) in Hamburg

The world talks about batteries, cells and the energy transition. Almost nobody talks about the Battery Management System (BMS) that makes them work.

As battery applications multiply, from robotics and mobility to data centers and grid-scale storage, BMS complexity is exploding. Legacy BMS architectures were never built for this: too rigid to keep up with new requirements, they've turned the BMS into the bottleneck of battery development.

We're building something different: a novel software-defined BMS architecture combined with an AI-driven configuration process. It gets battery manufacturers the right BMS for their exact use case within days, regardless of application or cell chemistry.

We're building the battery management system platform of tomorrow. Delivered in days, not years.

Join us and shape one of the fastest growing markets in the energy sector: The BMS market.

Our Motivation

At Anori Tech, we believe everything is energy, and progress runs on it. With Anori we actively shape the energy transition: from oil to electric, from low to high efficiency. We need batteries for this transition and almost all batteries need a BMS. We strive for Shenzhen speed and German engineering quality. Our objective: put Europe back on the map in the race for the energy transition and build technical leadership out of Hamburg.

About the Role

The BMS is where software meets power. As our Hardware Engineer, you'll own the hardware side of the Anori BMS with a focus on the power stage: power electronics, cell connection and protection circuits. At the same time, you'll be our go-to person for hardware testing and make sure every board holds up under real-world conditions, from HiL test benches to stress tests and EMC pre-compliance. You'll work closely with Stefan, our CTO, and our firmware engineers to take the BMS from a tested prototype to a fully certified product. The technology is proven, the funding is secured, and the hardware decisions you make now will define how every future Anori BMS works.

Start date: from January 1, 2027

What You'll Do

Design and develop the power stage of our BMS: the highest power density on the market

Make the trade-off between performance, reliability, supply chain and price for each part

Build and run hardware tests: HiL setups, stress tests, HALTs and failure analysis

Plan and run EMC pre-compliance testing and prepare the path to conformity

Bring up new boards and debug them together with the firmware team

Contribute across the entire BMS hardware, wherever you are needed

What You Bring

Must have

Solid foundation in electrical engineering, from the schematic to the PCB. You know the parasitic effects of every practical circuit and you design with them

Deep knowledge of power electronics: MOSFET switch design, SOA, gate drive, current sensing and loss budgets

Experience with protection circuits, e.g. overcurrent, short circuit, over- and undervoltage, reverse polarity

Circuit and thermal simulation, for example in LTspice, with model-to-hardware correlation on the bench

Confident in the lab: oscilloscopes, power supplies, electronic loads, thermal measurements and of course hand-soldering 01005 components

Critical, analytical, systematic thinking: you reason from first principles, make your assumptions explicit and challenge existing paradigms

Strongly preferred

A broad hardware skill set beyond the power stage: microcontroller circuits, analog sensing, communication interfaces (CAN, LIN, BLE, …)

Proven hands-on testing experience, including HiL tests and stress tests

Knowledge of DfM and new electronic manufacturing techniques, materials and general mechanical integration knowledge

Thermal design and cooling concepts for high-current paths

Wide-bandgap semiconductors and new switch topologies, and an interest to research and develop novel gate-drive techniques beyond standard drivers

Nice to have

High-voltage design above 60V: creepage and clearance, isolation, isolation monitoring and safe discharge

Experience with battery systems, cell connection and cell monitoring ICs (AFEs)

Test automation with Python

A background in safety-critical systems (IEC 61508, ISO 26262, …)

Knowledge in MBSE and requirements engineering methods (the skills, not the paper)

What We Offer

Work on a product with purpose that redefines the state of art: our product is a key part to enable competitive battery energy storage.

Work directly with the founding team on decisions that shape the company. The team is small, so your ideas will matter. A lot.

Challenging engineering in an industrial, but research-near environment. We bring research into the industry.

A modern stack and methods: Rust, MBSE, everything as code, and the best tools and techniques for the job, chosen on merit.

To be both supported and challenged: room to grow, and the expectation that you will.

You might be a fit if

You hold yourself to a high standard and don’t settle for "good enough."

You want to have a big say in what the Anori BMS looks like and how it works

You are eager to try out new tools and enjoy incorporating AI into your work to make your life easier and more productive

You are excited about startups and all the opportunities and uncertainties that come with it

You want to be an active part in accelerating the energy transition in Europe

You are comfortable with English as a working language

You are happy to be in the office most of the time because for fast decisions we need to be in the same room. We expect you to be in the office at least 3 days / week

P.S. Extra bonus if you tell us what your favorite type of tea is.

Anori Tech delivers a custom Battery Management System in days, not months. A configurable, software-defined BMS platform for battery manufacturers. We help Europe with the energy transition.
