# Electrical Engineer at Thaleron

- **Company:** Thaleron
- **Location:** Maidenhead, United Kingdom
- **Employment:** full-time
- **Work type:** onsite
- **Posted:** 2025-12-15
- **Last confirmed live:** 2026-09-12
- **Apply:** https://jobs.ashbyhq.com/thaleron/cf8c484e-f6ea-404c-b47b-208a62523dd0

## Job description

Who Are We? Thaleron is a seed-stage startup with a big goal, to make a carbon-free grid drastically cheaper than fossil fuels. There are three core foundations to achieving this - generation, storage and transmission. We were originally founded to develop an entirely new mechanical energy storage technology. We have proven it in the lab, and are now building our first scale prototypes. More recently, we've been working on the other foundation that is ripe for innovation, transmission. The DC transmission grid is central to large-scale renewable energy deployment, and the technologies and operating principles will significantly differ from traditional AC systems.

What You'll Do:

- Design high-voltage AC/DC converters with custom topologies and control strategies.
- Simulate and validate designs using PLECS, LTspice, MATLAB/Simulink, or similar tools.
- Build early-stage prototypes and test systems—own the bench as much as the whiteboard.
- Write real-time embedded firmware for converter control (microcontrollers or DSPs).
- Design and tune control loops, switching strategies, and fault-handling logic.
- Solve practical challenges in insulation, EMI, thermal management, and safety.
- Work at the intersection of hardware, firmware, and physics to create something truly original.

What We're Looking For:

- Degree in Electrical Engineering or related field, with experience in both power and embedded systems.
- Strong foundation in circuit theory and converter-level design
- Hands-on experience building and testing power electronics hardware.
- Proficient in embedded C/C++ for control systems, ideally with real-time constraints.
- Comfortable working in a fast-paced, low-structure R&D environment.
- Most importantly: a first-principles mindset and the drive to invent, not just optimize.

## Why This Is Different

- This isn’t iteration or integration—we’re developing a new power architecture from scratch.
- You’ll be part of a small, deeply technical team where your decisions shape the product.
- We care about real engineering—not just specs, but how and why things work.
- You’ll build hardware that directly impacts the future of energy storage and grid resilience.

Candidate Journey:

1. Talent Screen - video call (30-45 minutes) - an introductory call with our talent consultant.
2. Technical Interview - video call (60 minutes) - initial, technically focused interview with our founders.
3. Onsite meeting (120 - 180 minutes) - in-person meeting with the team in Maidenhead. You'll participate in a collaborative task and spend valuable time with the whole team.

This process is designed to give you every chance to get the measure of us, and us of you. The various stages give you a fair opportunity to show your unique strengths and qualities, and enables each of us to establish if we’re a good fit for the other.

Please share with us any individual needs or reasonable adjustments we may need to make in advance of commencing the interview process with us.

## About Thaleron

## Company Overview
- **One-liner**: Thaleron is building cheaper mechanical energy storage to enable a 100% clean grid.
- **Entity Type**: Private (Pre-Seed / Seed stage)
- **Headquarters**: Innsbruck, Austria (with presence in United Kingdom and Portugal)
- **Founded**: 2022 (Incorporated 31 January 2022)
- **Founders**: Jorgen Tveit (Co-founder)

## Core Business
- **Primary industry**: Renewable Energy Equipment Manufacturing / Energy Storage
- **Target customers**: Utility companies, grid operators, and renewable energy developers (B2B / Enterprise)
- **Mission or purpose statement**: "Building cheaper mechanical energy storage to enable a 100% clean grid."

## Products & Services
- **Mechanical Energy Storage System**: A novel, low-cost mechanical solution based on proven technologies (likely flywheel-based, with patents related to flywheel energy storage) designed to provide grid-scale energy storage at significantly lower cost than current alternatives. The system is currently in prototype development.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Total Funding**: At least 2 funding rounds (Pre-Seed in March 2023 with 2 investors; Seed in November 2023 with 1 investor). Exact amounts not publicly available.
- **Notable Investors/Partners**: Investors are undisclosed. Key team members have backgrounds at Dyson, Imperial College London, UK Atomic Energy Authority, and First Light Fusion.
- **Growth Signals**: Very early-stage (5 employees, ~1,253 monthly website visits). The company is actively hiring for Mechanical and Electrical Engineers, indicating a push toward building a prototype. A Google patent related to flywheel energy storage was published in January 2024, suggesting active R&D.

## Competitive Advantages
- **First-principles engineering approach**: The team emphasizes a strong theoretical foundation and creative problem-solving, aiming to reinvent energy storage rather than incrementally improving existing technologies.
- **Proven technology base**: The solution builds on well-understood mechanical principles (flywheels), reducing technical risk compared to untested chemical or novel physics-based storage.
- **Small, elite team**: The company prioritizes hiring exceptional generalist engineers who can own designs end-to-end, fostering a high-agility, low-bureaucracy environment.

## Strategic Focus
- **Prototype development**: The immediate priority is building and testing a working prototype of their mechanical storage system.
- **Team building**: Actively recruiting senior mechanical and electrical engineers to accelerate development.
- **Unlocking the energy transition**: The long-term goal is to provide the missing piece for a 100% renewable grid by making storage economically viable.

## Why Work Here
- **High-impact mission**: Directly working on a critical problem for the energy transition and climate change.
- **Very hands-on, small team**: Engineers at all levels are expected to be deeply involved in building the prototype, offering significant ownership and impact.
- **First-principles culture**: The company values deep theoretical understanding and creative, resourceful problem-solving over following industry norms.
- **Remote-first with office hub**: Employees work remotely, with an office presence in Maidenhead, Berkshire, UK. The company is headquartered in Innsbruck, Austria, and has team members in Portugal.
- **Exceptional team**: Colleagues come from top engineering backgrounds (Dyson, Imperial College, UK Atomic Energy Authority, First Light Fusion), creating a high-caliber peer group.
