Our focus is on capturing civilizational levels of ultra-low-cost renewable energy for applications including computing and affordable renewable fuels delivered to shore.\n\nThe company is a public benefit corporation headquartered in Portland, Oregon, and backed by leading venture capitalists, philanthropic investors, university endowments, and private investment offices. We operate as an idea meritocracy in which the best ideas change the company's direction on a regular basis.\n\nOur staff have worked at organizations such as SpaceX, Blue Origin, Boeing, Tesla, Apple, Virgin Orbit, Astra, Google, Amazon, Microsoft, New Relic, Bridgewater, Raytheon, Disney Imagineering, and the US Army and Air Force, as well as research universities, startups, and small companies across a range of industries.\n\nAbout the Job\n\nOur 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.\n\nYou will 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. You will also work closely with our networking and security engineers to ensure onboard systems communicate reliably and remain free of critical vulnerabilities. Your work will directly shape how data is captured, moved, and understood onboard, enabling resilient autonomy and breakthrough operational insight for the rest of the company. As such, you should feel comfortable communicating effectively across the boundaries of teams and disciplines.\n\nIn addition to developing new capabilities, you will build on our existing development processes and tooling to further enhance the quality and reliability of our onboard software – expanding unit testing frameworks, automated integration tests, continuous deployment pipelines, and code reviews and documentation.\n\nCandidates should have strong interpersonal skills and be able to thrive in a creative, scrappy, and collaborative environment in which the best ideas change the company's direction on a regular basis. You will own your designs cradle-to-grave, from first concept through fabrication and deployment at sea. If you are an excellent engineer, regardless of your background, we want you to apply.\n\nResponsibilities\nBuild and maintain the network-facing software layers that enable the Node to communicate reliably with shore – from low-level connection handling to higher-level data exchange protocols.\nDesign egress telemetry pipelines that use bandwidth efficiently, weighing tradeoffs between data fidelity, timeliness, and link constraints.\nCollaborate on APIs and schemas for command, control, and telemetry exchanges between subsystems, ensuring reliability is built in from the start.\nPartner with network engineers to ensure a cohesive strategy for how bandwidth is divided and prioritized among competing data streams – telemetry, command and control, diagnostics, etc. – ensuring consistent allocation and fulfillment of bandwidth budget.\nEnsure that software degrades gracefully during connectivity loss or link degradation – including buffering, retry logic, and prioritized retransmission – so critical data isn't lost when links drop.\nWork with network and security engineers to review onboard software for vulnerabilities, harden network-facing services, and ensure telemetry and control interfaces meet the company's security standards before deployment.\nAnalyze system performance and implement optimizations for latency, throughput, and resource efficiency.\nExtend and improve existing unit testing frameworks, integration tests, and CI/CD pipelines.\nStrengthen code review, documentation, and general software engineering practices within the team.\nParticipate in design reviews, architecture discussions, and cross-team technical collaborations.\nRequired Qualifications\n7+ years of experience developing software.\n3+ years of experience with data-intensive or mission-critical systems.\nProficiency in a systems programming language (Rust, C++, or similar).\nProficiency with version control (we use git).\nCompetency with CI/CD pipelines for automated tests and deployment.\nExperience building or maintaining network-facing software – handling connection lifecycles, protocol implementation, or communication reliability in production systems.\nUnderstanding of fundamentals in computer networking (L2–L4), transport protocols, congestion control, and distributed systems.\nExperience designing systems for constrained, high-latency, intermittent, and/or expensive links (e.g., satellite, maritime, remote ops).\nFamiliarity with security principles for networked systems (authentication/authorization, encryption, key management).\nAbility to work in a fast-paced and self-starting atmosphere.\nAbility to communicate thoughtfully and empathetically with people from many different educational and professional backgrounds.\nMotivation and curiosity to learn a wide variety of concepts across many disciplines, not just software engineering!\nDesired Qualifications\nExperience with Rust, particularly in building reliable, high-performance software systems.\nExperience with real-time or safety-adjacent systems where reliability is critical.\nBackground in robotics, aerospace, or marine systems with a focus on data processing.\nFamiliarity with time-series databases, streaming analytics, and data pipelines for telemetry and monitoring applications.\nExperience with containerized build environments for developing, testing, and deploying software.\n\nWe encourage you to apply even if you do not meet every desired qualification. If you are a strong software engineer motivated by building resilient, high-quality, mission-critical onboard systems, we want to hear from you.\n\nAdditional Requirements\n\nIntermittently able to work longer hours and weekends to support critical needs. While we expect a lot of each other, we also offer a high degree of autonomy and work-life balance, including unlimited PTO and flexible working hours.\n\nCompensation and Benefits\n\nIf hired for this full-time role, you will receive:\n\nCash compensation of $175,000–$230,000.\nEquity in the company. We're all owners and if we're successful, this equity should be far and away the most valuable component of your compensation.\nA benefits package that helps you take care of yourself and your family, including:\nFlexible paid time off\nHealth insurance (the company pays 100% of gold-level PPO plan for full-time employees, their partners, and dependents)\nDental insurance (the company pays 100% for full-time employees, their partners, and dependents)\nVision insurance (the company pays 100% for full-time employees, their partners, and dependents)\nDisability insurance (the company pays 100% for a policy to provide long-term financial support if you become disabled)\nAbility to contribute to tax-advantaged accounts, including 401(k), health FSA, and dependent care FSA\nRelocation assistance to facilitate your move to Portland (if needed).\nLocation\n\nThis can be a remote position. Our offices, lab, and shop are located in Portland, Oregon.","company":"Panthalassa","rawCompany":"panthalassa","city":"Gladstone","state":"OR","isRemote":false,"isActive":false,"createdAt":"2026-09-17T09:28:00.000Z","occupations":[{"code":"15-1252.00","title":"Software Developers","slug":"software-developers"},{"code":"15-1299.08","title":"Computer Systems Engineers/Architects","slug":"computer-systems-engineers-architects"},{"code":"15-1251.00","title":"Computer Programmers","slug":"computer-programmers"}],"industries":[{"code":"513210","title":"Software Publishers","slug":"software-publishers"},{"code":"541512","title":"Computer Systems Design Services","slug":"computer-systems-design-services"},{"code":"541511","title":"Custom Computer Programming Services","slug":"custom-computer-programming-services"}],"jobPosting":{"@context":"https://schema.org","@type":"JobPosting","title":"Senior Software Engineer, Core Systems","description":"About the Company\n\nWe 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.
