Job Title:

Platform SW Engineer III

Are you looking for a role that has meaning and purpose on a team that is crafting the future of security? Evolv’s R&D team is looking for an experienced and innovative

Platform Software Engineer to  provide technical leadership, improve software engineering practices, and be hands on with our team ofSW engineerswithexpertisein embedded, real-time,and computer vision. In Evolv’s fast-paced development environment,the R&D team is continuously innovating new features and integrating complementary technologies into our products.

• Demonstrate technical depth and earn the respect of senior developers.
• Learnthe product’s hardware architecture.
• Review existing code and software architecture.
• Get hands-on in Yocto, contributing to Evolv’s custom Linux distribution.

• Ship production-quality pull requests for small-to-medium features, with your first landing by day 30–45.
• Assess the current product roadmap, BSP structure, and repository organization, and outline a platform strategy so future product lines share a common, reliable software foundation.
• Actively contribute to architecture and design discussions, surfacing risks and improvements.
• Evaluate the current CI/CD and build-automation setup andlandat least one concrete improvement.
• Get fluent in Evolv’s full software development lifecycle, including Dev Ops, QA, and hardware integration touchpoints.

• Own the architecture of reusable, enterprise-grade C++ platforms — modular, cleanly abstracted, and built for reuse across product lines (see “Enterprise-Level Software Development” below for the full scope).
• Lead at least one internal technical workshop or knowledge-sharing session.
• Improve cross-functional workflows around testing, deployment, and system reliability.
• Help define and enforce coding standards and best practices across the team.
• Weigh in on long-term architectural decisions and product roadmap planning.

  Yoctorecipes, layers, and configurations.
• Write,modify, and optimize
  
  Linux kernel device trees to map custom hardware peripherals and ensure clean boot routines.
• Debug low-level Linux kernel issues (boot failures, driver crashes, interrupt/DMA issues) using standard embedded Linux tooling (JTAG, serial console, kernel logs,ftrace/perf).
• Own the secure boot and provisioning pipeline end to end — signed images, secure key storage/injection, fused security state — from design through production readiness.
• Diagnose hardware-software interface boundaries, including real-time timing constraints, power profiles, and thermal behavior.
• Design and implement real-time systems interfacing with Linux on an SoC, meeting deterministic, low-latency requirements.

• Design reusable, enterprise-grade C++software
  -modularcomponentreuse and clean API abstraction, built for longevity across multiple product lines.
• Managecomponentversioning,dependency trees, and decoupling strategies in resource-constrained environments.
• Write production-quality C/C++17 for both user-space applications and kernel-adjacent components.
• Apply advanced design patterns and object-oriented principles to keep core libraries scalable and maintainable.
• Build multithreaded applications using modern C++ concurrency primitives, thread synchronization, and lock-free techniques.
• Write clean, well-documented, testable code;maintain quality through peer review and…
