To pave the way for secure AI adoption in enterprises, ensuring innovation thrives without compromise.
Role
Who you are
- We’re looking for a hands-on systems engineer with deep expertise in Rust (or C++ with a strong willingness to learn and embrace Rust as your primary language) to help us build and evolve security critical client software
- Strong hands-on experience with Rust (or C++ with a strong willingness to learn Rust) in production systems
- Solid grasp of systems programming concepts: memory safety, lifetimes, threads, channels, error handling, IPC
- Familiarity with platform APIs and subsystems on Linux, Windows and macOS
- Experience building CI-tested, reproducible builds for native applications
- Proficiency with common developer tooling: Git, code review, CI pipelines, structured logging, crash analytics
- Networking skills and security fundamentals is a plus
Desirable
- Have a strong development background and a rigorous approach to testing and validation
- Relish the prospect of writing code that will run on millions of devices and needs to be reliable and performant around the clock
- Enjoy working close to the OS and care deeply about software performance, correctness and safety. Previous Kernel or system-level development experience is a great nice-to-have
- Can build and ship reliable systems fast, with a sharp eye for edge cases and long term impact and maintainability
- Learn quickly and independently, with great attention to detail and high standards
- Have made contributions to open-source Rust (or C++) projects or RFCs
- Believe that good tooling and documentation are part of engineering, not afterthoughts
- Thrive in fast-paced startup environments where ambiguity is the norm
- See AI as a tool to help you build smarter, faster and better
What the job involves
- You will work on low level security agents and cross platform components that run on user devices, with a strong emphasis on robustness, performance and security
- Your work will power core functionality in how we collect signals, and manage on-device controls for app usage and data movement
- You will join a fast-moving team that ships frequently and cares about correctness, observability and maintainability
- Design, implement, and optimise endpoint security agent components in Rust, targeting desktop and/or server platforms (Windows, macOS, Linux)
- Build robust tests, validation tooling and deployment mechanisms for client facing releases that impact our customers in their everyday work
- Conduct exploratory technical research to understand the art of the possible and how to best approach implementation of new product features
- Investigate and resolve platform specific issues with precision and speed
- Work closely with security engineers, backend engineers, and product stakeholders to shape technical requirements
- What Success Looks Like
- You’ve shipped production Rust or C++ code that runs safely and efficiently across platforms
- Your components are well tested, observable, and resilient to partial failures or bad input
- You identify performance or architectural bottlenecks before they reach users
- You actively reduce complexity in critical code paths without compromising clarity or functionality
- You consistently deliver high-quality changes on a tight feedback loop, including regression-safe updates

Our take
The power of generative AI has made businesses across industries move quickly to adopt the technology. But this quick adoption has raised security concerns, especially surrounding how businesses can protect sensitive information without slowing down innovation.
This is where Harmonic Security steps in, with data protection built for the gen-AI era. It tracks AI adoption, use cases and risk, helping businesses to gain visibility into how their employees are using gen-AI, and monitor the exposure of their data to risky applications.
This approach means that businesses can detect data privacy risks while adopting gen-AI safely. So it's a welcome tool for those who want to build out a competitive edge without risking data breaches. It now plans to scale up its engineering and go-to-market efforts off the back of a successful funding round.
