How we know
It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.
Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Thaleron, so its true age is longer.

Not stated: Pay, real vacancy, AI screening.
Why these three
Ontario requires postings from employers with 25 or more staff to state the pay, whether the vacancy exists, and whether AI screens applicants.
Some employers add pay only on their own site. Check the original posting before you rule it out.

About the role
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.
