Hoplynk is looking to solve the problem of resilient connectivity for autonomous systems and mission-critical operations in any environment by building the communications and networking layer for the intelligent edge.

Requirements

• Deep experience in embedded Linux firmware and system software development.
• Strong proficiency in Rust with a solid understanding of low-level concepts and safety-critical systems.
• Experience with Yocto or Buildroot, U-Boot, secure or verified boot, and device tree configuration.
• Proven experience designing and maintaining OTA and firmware update systems.
• Ability to debug hardware-software issues with tools such as JTAG, serial consoles, and analyzers.
• Familiarity with production testing, bring-up, and hardware verification workflows.
• Experience with OpenWrt or edge compute modules such as Jetson, i.MX, IPQ, or Rockchip.

Responsibilities

• Own the architecture and implementation of our Rust-based embedded firmware stack.
• Set up and maintain build systems using Yocto or Buildroot for multiple SoMs and platforms.
• Design and implement reliable OTA updates with A/B partitions, signatures, and rollback.
• Build firmware observability tools including structured logs, metrics, and diagnostics.
• Bring up new hardware: bootloader setup, device trees, kernel configuration, and board support.
• Develop and optimize low-level Rust drivers for networking, wireless, and I/O interfaces.
• Build firmware CI and testing systems including hardware-in-loop and automated flashing.

Other

• Full-time position
• Pre-seed startup experience
• Clear communication and documentation habits, with a practical mindset for shipping reliable systems.
• Ability to work closely with the networking and systems teams
• Autonomy to shape how our firmware is built, tested, and delivered in the field.
