Senior Aggregate Manager Jobs in Portland, OR (NOW HIRING)

Job Summary:
Panthalassa is a renewable energy and ocean technology company committed to ensuring a sustainable future for Earth. As a Senior Software Engineer on the Core Systems team, you will contribute to the design, development, and optimization of onboard data aggregation and telemetry systems.
Responsibilities:
• Build and maintain the network-facing software layers that enable Node to communicate reliably with shore – from low-level connection handling to higher-level data exchange protocols.
• 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 – telemetry, command and control, diagnostics, etc. – ensuring consistent allocation and fulfillment of bandwidth budget.
• Ensure 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.
• Work 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.
• 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.
Qualifications:
Required:
• 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!
Preferred:
• Experience with Rust, particularly in building reliable, high-performance software systems.
• Experience with real-time or safety-adjacent systems where reliability is critical.
• Background in robotics, aerospace, or marine systems with a focus on data processing.
• Familiarity with time-series databases, streaming analytics, and data pipelines for telemetry and monitoring applications.
• Experience with containerized build environments for developing, testing, and deploying software.
