Role Description Our core technology is the Node, a device that produces energy in the ocean’s harshest conditions for years without human maintenance or intervention. As a Senior Software Engineer on the Core Systems team, you will contribute to the design, development, and optimization of the onboard data aggregation and telemetry systems. - Work with our Core team and partner with Shore-side software engineers to build reliable data pipelines, low-latency telemetry paths, and storage systems that function in constrained, unpredictable marine environments. - Collaborate closely with networking and security engineers to ensure onboard systems communicate reliably and remain free of critical vulnerabilities. - Shape how data is captured, moved, and understood onboard, enabling resilient autonomy and breakthrough operational insight for the rest of the company. - Enhance the quality and reliability of our onboard software by expanding unit testing frameworks, automated integration tests, continuous deployment pipelines, and code reviews and documentation. Qualifications - 7+ years of experience developing software. - 3+ years of experience with data-intensive or mission-critical systems. - Proficiency in a systems programming language (Rust, C++, or similar). - Proficiency with version control (we use git). - Competency with CI/CD pipelines for automated tests and deployment. - Experience building or maintaining network-facing software – handling connection lifecycles, protocol implementation, or communication reliability in production systems. - Understanding of fundamentals in computer networking (L2–L4), transport protocols, congestion control, and distributed systems. - Experience designing systems for constrained, high-latency, intermittent, and/or expensive links (e.g., satellite, maritime, remote ops). - Familiarity with security principles for networked systems (authentication/authorization, encryption, key management). - Ability to work in a fast-paced and self-starting atmosphere. - Ability to communicate thoughtfully and empathetically with people from many different educational and professional backgrounds. - Motivation and curiosity to learn a wide variety of concepts across many disciplines, not just software engineering! Requirements - Build and maintain the network-facing software layers that enable Node to communicate reliably with shore. - Design egress telemetry pipelines that use bandwidth efficiently, weighing tradeoffs between data fidelity, timeliness, and link constraints. - Collaborate on APIs and schemas for command, control, and telemetry exchanges between subsystems, ensuring reliability is built in from the start. - Partner with network engineers to ensure a cohesive strategy for how bandwidth is divided and prioritized among competing data streams. - Ensure that software degrades gracefully during connectivity loss or link degradation. - Work with network and security engineers to review onboard software for vulnerabilities and harden network-facing services. - Analyze system performance and implement optimizations for latency, throughput, and resource efficiency. - Extend and improve existing unit testing frameworks, integration tests, and CI/CD pipelines. - Strengthen code review, documentation, and general software engineering practices within the team. - Participate in design reviews, architecture discussions, and cross-team technical collaborations. Benefits - Cash compensation of $175,000–$230,000. - Equity in the company. - Flexible paid time off. - Health insurance (the company pays 100% of gold level PPO plan for full-time employees, their partners, and dependents). - Dental insurance (the company pays 33% for full-time employees and 100% for their partners and dependents). - Vision insurance (the company pays 100% for full-time employees, their partners, and dependents). - Disability insurance (the company pays 100% for a policy to provide long-term financial support if you become disabled). - Ability to contribute to tax-advantaged accounts, including 401(k), health FSA, and dependent care FSA. - Relocation assistance to facilitate your move to Portland (if needed). Company Description We are a renewable energy and ocean technology company committed to rapidly developing and deploying technologies that will ensure a sustainable future for Earth by unlocking the vast energy potential of its oceans.
