Lead Rust Software Engineer - Two Six Technologies

Overview of Opportunity 

Two Six Technologies is seeking a Lead Rust Software Engineer to drive the development of secure, high-performance embedded systems written primarily in Rust. In this role, you’ll leverage Rust’s memory-safety and concurrency guarantees to implement robust, low-level software on bare-metal and RTOS-based platforms. As part of an interdisciplinary design team, you’ll apply security-first design principles, integrating cutting-edge hardware, cryptography, and toolchains to build resilient systems from the ground up. Working alongside other passionate, mission-driven professionals, you’ll help transition innovative prototypes into reliable, large-scale solutions supporting critical national security objectives.

Responsibilities Include:

• Maturing proof-of-concept R&D technology to operational fieldable solutions
• Hardware/Software co-design: Bridging the gap between software and hardware
• Developing unit, integration, and hardware-in-loop test regimens to ensure high reliability and resilience in delivered products
• Implementing boot-time integrity verification and secure field update capabilities
• Development of secure, reliable software, utilizing modern hardware security primitives, best practices, and memory-safe programming languages/strategies.
• Support of scalable and modular design methodology
• Engaging in technical exchanges with transition partners and key stakeholders

Minimum Qualifications:

• Bachelor’s degree in Computer Science, Computer/Electrical Engineering, or related technical domain
• Minimum of 7 years of experience with one or more of the following modern development languages: Python, C , C++, Embedded C
• Minimum of 2 years experience with Operating Systems internals (privilege and user groups, binary memory layout) and/or Trusted Execution Environments such as ARM TrustZone
• Experience developing memory-safe applications in the Rust programming language
• Active Top Secret Clearance (candidate must be willing to pursue higher clearance levels including those requiring a polygraph)
• Ability to work on-site at Arlington, VA headquarters

Nice to haves:

• Strong leadership and project management skills, with the ability to mentor junior engineers and drive technical execution.
• Experience with Rust for embedded applications, especially embassy-rs for STM32 microcontrollers.
• Experience developing and/or customizing bootloaders such as WolfBoot, implementing secure firmware update using digital signatures
• Basic understanding of memory management concepts (Heap, Stack, Virtual Memory, MMU, Physical vs. Virtual)
• Experience with testing, CI/CD pipelines, and virtual machine test ranges
• Experience with firmware/driver development across Linux and/or Windows Operating Systems
• Top Secret//SCI clearance with polygraph
• Graduate degree in Computer Science, Computer/Electrical Engineering, or related Scientific Domain

Security Clearance:

• Active Top Secret Clearance (candidate must be willing to pursue higher clearance levels including those requiring a polygraph)
