Title: Senior Onboard Software Engineer Location: Mountain View CA US Job Description: Matternet is building the future of delivery with autonomous drone networks that move critical goods faster, cleaner, and at lower cost. We work with partners across healthcare, logistics, food, and retail to deliver everything from medical items to everyday essentials, safely and reliably. We’re seeking a Senior Onboard Software Engineer to develop the software that runs on our aircraft and ground assets. Working primarily in C++ on embedded Linux, you’ll develop and harden the safety-critical subsystems that allow our drones to fly autonomous Beyond-Visual-Line-of-Sight (BVLOS) missions across varied environments, from open airspace to dense, urban areas. This is a senior individual-contributor role with real ownership: you'll own specific subsystems end-to-end, drive implementation through simulation and flight test, and partner with teams across the company to validate and support them in the field. In this role, you will: - Own safety-critical onboard subsystems that enhance our UAS capabilities and safety mitigations - Build the systems that allow aircraft to fly autonomously in demanding environments, including dense urban airspaces - Deliver major customer-facing features on flight and ground assets, while balancing performance, safety, and reliability - Drive software verification and release, from simulation and flight test to deployment across production fleets - Provide senior technical support, triaging and solving field and flight-test issues - Collaborate with stakeholders within Engineering, Operations, Safety, and Production Requirements - 5+ years of production software engineering, owning major subsystems end-to-end - Expertise in C++ or later, multithreading, real-time messaging, and algorithm design and optimization - Strong Linux background and experience with cross-compiling - Experience with Python, YAML, and other scripting tools - Solid applied math skills (geometry, coordinate transforms, kinematics) for navigation and avoidance - Proven ability to implement and validate complex native systems and validate them in simulation and on hardware - Proficiency with version control and peer code review workflows (e.g. Git) - Excellent technical communication and strong cross-disciplinary teamwork in a fast-paced environment Preferred Qualifications: - UAV, autonomous robotics, aerospace, or other safety-critical regulated experience - Experience using AI coding assistants to accelerate development - Familiarity with an autopilot stack such as ArduPilot or PX4 - Computer vision and perception (OpenCV or similar) and sensor integration - Experience with Docker, and containerized build, test, and development environments - Experience with distributed systems, networking, and fleet management - Relevant mechanical, aerospace, or electrical engineering experience Work Environment: - In-person role based at Matternet Headquarters and access to our flight test facility - The ability to work and communicate efficiently online with a hybrid team is critical to success Benefits At Matternet, we’re advancing a new era of logistics, one where autonomous drones deliver what matters faster, cleaner, and more efficiently. We know our mission is challenging, but it's worth it, and we are committed to taking care of the people who make it possible. - Compensation: The expected starting range for this role is $180,000–$240,000, based on San Francisco Bay Area market data. This range reflects the target starting pay for candidates who meet the minimum qualifications for the role. Final compensation will depend on factors such as your experience, skills, level, location, and potential impact. - Total Rewards: In addition to base pay, our compensation packages include equity and benefits such as medical, dental, vision, life, and disability coverage, flexible spending accounts (FSA), unlimited paid time off, company holidays, and a 401(k) plan.

Role Description We are seeking a Senior Principal Engineer to drive the architectural strategy and technical execution across our 80+ engineer Application Portfolio, encompassing all Web, Mobile, and Headless surfaces. This is a high-impact, individual contributor role where you will set the vision for our technology transformation, bridging the gap between deep frontend architecture and scalable, agentic API-first platforms. You will partner with Product leadership to drive customer-obsessed engineering, ensuring that our technical choices directly accelerate product velocity and user value. Responsibilities - Architectural Vision: Define and drive the technical strategy for the entire Applications Portfolio, establishing deep frontend architecture standards (Web, Mobile, Headless) to ensure consistency, scalability, and performance. - Mentorship & Leadership: Act as a key mentor and coach to senior engineering talent, fostering a culture of technical excellence, high-impact decision-making, and proactive problem-solving. - Product-Engineering Synergy: Collaborate deeply with Product leadership to drive roadmaps, ensuring engineering strategy is inherently aligned with customer needs and product evolution. - Strategic Alignment: Facilitate alignment and clarity across teams regarding goals, outcomes, and timelines for complex, multi-team projects. - Technology Transformation: Spearhead the evolution of our application architecture from a 'feature factory' model to a platform-driven system, modernizing API layers and integrating emerging standards like the Model Context Protocol (MCP) to enable next-generation agentic workflows. - Design Systems Partnership: Partner closely with Design Systems teams to define and influence the evolution of shared UI components and design tokens, ensuring seamless integration with engineering architectural standards. - Technical Governance: Identify and reduce systemic technical risks, enforce design principles, and raise the bar through hands-on technical reviews and prototyping. Qualifications - Extensive experience (15+ years) as a senior/principal-level software engineer with deep expertise in Frontend architecture and large-scale application systems. - Proven success leading technology transformation across organizations of 80+ engineers. - Deep understanding of modern API design (REST, GraphQL) and its application in highly distributed, agentic environments. - Demonstrated experience with the Model Context Protocol (MCP) or similar agent-integration patterns. - Strong product mindset: proven history of collaborating with Product leaders to solve complex customer problems with customer-obsession. - Ability to balance high-level architectural strategy with hands-on, production-level coding. - Extensive experience evaluating and adopting new frontend technologies and frameworks, expertly balancing innovation with long-term maintainability. - Proven track record of designing and scaling robust frontend architectures that support high-traffic, complex user interfaces across massive datasets. - Exceptional communication skills, with the ability to facilitate clarity and drive consensus across distributed teams.
