About Us

Tune Zilla is an automotive performance software company that builds proprietary ECU/TCU flashing tools, communication protocols, and a tuning platform used by a global network of calibrators and dealers. We work across VAG, Mercedes, BMW, and a growing list of OEMs.

From reverse engineering vehicle protocols to building robust, production-ready implementations, our work sits at the intersection of embedded systems, automotive engineering, and software. This isn’t just backend or app development, it’s hands-on, close-to-the-metal engineering that directly interfaces with real vehicles.

Our team is small, highly technical, and team-oriented. We move fast, share ideas openly, and take ownership of what we build.

About the Role

This posting is for a Mon-Fri on-site Software Engineer role on our Flash Development team. As a member of this team you will design, develop, test, and maintain the ECU communication protocols that sit at the core of our flashing tools - the layer that talks directly to vehicle hardware, this includes:

- Reverse engineering automotive firmware
- Implementing and maintaining our flashing tool in C/C++
- Working with boot modes, diagnostic protocols, CAN bus, and the specific quirks of how different ECUs authenticate, read, and write.
- Device testing (in-vehicle and bench)
- Working through complex edge cases and unknowns

What we’re looking for

- Strong background in embedded systems, reverse engineering, or low-level software development




- Solid experience with C/C++

- Experience with electronics and bench testing
- Self-starter with the ability to work independently.
- Quick learner with a passion for technology.

Nice to have (but not required):

- Experience with automotive communication protocols (e.g. CAN bus, ISO 9141, ISO 15765, UDS, K-Line)
- Experience with low-level programming languages like Assembly.

Why you might like working with us

- You’ll be working on a real product used by real users
- Your work has direct impact — no “code that never ships”
- Small team, no heavy process — your ideas actually matter

Interview Process
