Senior Software Engineer, Imaging C++ 
Location: Hybrid Position, Greater Boston, MA Area

Company Description
RaySecur is a rapidly growing security technology company transforming how organizations detect hidden threats. Our patented imaging systems—used by Fortune 500 companies and government agencies worldwide—are the first desktop scanners capable of seeing inside objects in real time and in 3D, delivering X-ray–like imaging without harmful radiation.

At RaySecur, we combine deep technical innovation with a mission-driven mindset: protecting people and organizations from hidden threats. Our team is entrepreneurial, collaborative, and driven to challenge the status quo while delivering solutions that make the world safer. We are committed to excellence in our work and to fostering a culture built on trust, care, and shared purpose.

Job Description
We’re building real-time imaging systems at the intersection of custom hardware, terahertz sensing, and high-performance C++ software—and we’re looking for a senior engineer who wants deep technical ownership, meaningful influence, and a team where every voice genuinely matters. This is a hands-on, senior-level role focused on designing and delivering performance-critical systems in a security-focused environment. You’ll work close to the hardware, collaborate across disciplines, and help shape how our products evolve from R&D into production-grade systems.

What You’ll Do

• Architect and develop high-performance C++ software that integrates directly with custom imaging hardware
• Design and optimize real-time, multithreaded systems for low-latency image acquisition and processing
• Build and evolve image processing pipelines in collaboration with imaging and AI engineers
• Integrate AI/ML models into production systems with a focus on inference performance, reliability, and system constraints
• Contribute to building software that meets security, reliability, and robustness requirements appropriate for sensitive environments
• Collaborate using Atlassian tools (Jira, Confluence) to plan, track, and deliver work
• Own meaningful architectural decisions and contribute to long-term technical direction

• 5+ years of professional experience developing production-grade software in modern C++
• Strong experience with multithreading, concurrency, and performance optimization
• Background building software close to hardware, real-time systems, or complex external interfaces
• Experience with image processing, computer vision, or data-intensive pipelines
• Comfort working in Linux and Windows environments
• Familiarity with Jira or similar engineering workflow tools
• Strong communication skills and collaborative mindset

• Experience working in security-sensitive or regulated environments
• Exposure to secure coding practices or system hardening
• Embedded or firmware-adjacent development experience
• Frontend experience (Electron, React, or similar)
• Cloud or IoT integrations (e.g., AWS IoT)
• SQL or NoSQL database familiarity

What to Expect at RaySecur:
Joining RaySecur means working alongside a diverse and highly skilled team committed to solving meaningful security challenges. Our environment is fast-paced, collaborative, and focused on continuous learning, giving employees the opportunity to contribute to impactful technology while developing their own expertise.

We support flexibility and work-life balance, offering both remote and in-office work options depending on the role. Team members receive hands-on training, access to professional development opportunities, and the support of a leadership team that prioritizes open communication, transparency, and mentorship. At RaySecur, individuals are trusted to take ownership of their work while collaborating closely to achieve shared goals.

We look forward to meeting you!
