Software Engineer (Endpoint)

🌍 We’re making security suck less for developers. Security tools haven’t kept up with how software is built today. They interrupt teams, slow releases, and turn security into a bottleneck instead of a capability. We built Aikido to change that. Aikido builds developer-first security products that reduce real risk without getting in the way of shipping software. We focus on what actually matters and automate the rest. We’re taking on legacy security tools teams have been stuck with, and we’re winning. If you want to help us take market share and build products developers actually enjoy using, you’re in the right place. Founded in 2022 by third-time founders, Aikido has $85M in the bank and a long runway ahead. We’re building toward self-securing software. Join an all-star team. Take real ownership. Push boundaries. Build things that matter. As a Software Engineer (Endpoint), you'll be working closely with the Aikido team. Responsibilities Design, build, and maintain endpoint agent components in Rust, Go, and C++ across Windows, macOS, and Linux, with a focus on performance, stability, and low resource footprint. Develop and maintain kernel-level and privileged code: Windows minifilter/WFP drivers and ETW consumers, macOS System/Endpoint Security Extensions, and Linux eBPF/LSM-based sensors. Implement telemetry collection, process/file/network event tracing, and real-time detection and prevention logic in coordination with threat research and detection engineering teams. Debug complex issues in production and at the OS boundary — crashes, BSODs/panics, race conditions, and compatibility regressions across OS versions — using WinDbg, LLDB, and crash dump analysis. Own code quality and release readiness: code reviews, unit and integration tests, driver signing and packaging, and secure coding practices for code running with the highest system privileges. Really comfortable in a very entrepreneurial environment Can think along with architectural and impactful decisions Willing to learn new languages when the product requires it Comfortable researching and tackling hard problems and algorithms (eg parsing with ASTs) Willing to experiment (and also willing to perhaps throw away some code) Medior to Senior: We are going fast and need experienced people that can hit the ground running with us. You need to be comfortable with the above mentioned languages and tech-stack. No stranger to implementing automated testing platforms and unit tests Fluent in English Candidates must be located in Iași , Romania or Ghent, Belgium What you can expect Short decision lines. Big ownership. Shape the projects that matter and ship fast. Grow as fast as we do. Take on more, own more, and carve out your own path. Top-tier tech pay and equity. High trust, strong values, zero corporate BS. Flexibility in working hours. A company that sticks to its values in an open and informal atmosphere. We hire for talent, drive, and potential. Everything else is noise.
