• Own the end-to-end architecture of the eBPF-based routing simulation layer, including XDP and TC hook point design, BPF map structure, and synthetic ICMP TTL-exceeded generation that makes traceroute and MTR behave correctly against the simulated topology • Design and build the control-plane topology database and the pipeline that compiles real-world internet topology data into a form that in-range agents can consume and apply • Architect the in-range proxy agent: the lightweight component that bridges the persistent control plane to individual cyber ranges, applying topology configuration locally and handling DNS delegation and traffic forwarding • Define the interface contract between the control plane and in-range agents, including topology update propagation, graceful degradation when control plane connectivity is interrupted, and agent lifecycle management • Serve as technical lead for the team — making daily architectural decisions across the full service scope, conducting design reviews, and maintaining engineering quality across all four engineering roles on the team • Partner with other Engineers on novel simulation challenges, bring independent judgment to architectural tradeoffs, and shape the technical roadmap • Mentor engineers on the team, raising the bar on systems design, kernel-level debugging, and engineering rigor • Collaborate with adjacent platform teams on the operational model for a long-lived, multi-tenant service serving active cyber range deployments

• Ship customer-facing AI features across the full stack. • Treat AI output as something you verify, not assume. • Sweat the front-end craft. • Stay close to customers. • Own outcomes, not just output. • Co-author the solution. • Own production readiness from the start. • Use AI tools every day as part of your craft. • Help us hire.

• Contribute to building and maintaining agentic AI workflows using LangGraph. • Design and extend our growing library of MCP servers. • Improve the RAG pipelines that power our knowledge-retrieval systems, primarily in Python. • Work closely with a tight-knit team where your ideas carry weight and your contributions are visible.

Role Description The Hydrodynamics and Stability Lead commands the hydrodynamics, seakeeping, and stability architectures of Ocean Atomics’ floating energy platforms, driving the core naval architecture discipline required to secure class and regulatory approvals for our fleet. This role holds ultimate accountability for how our platforms interact with the marine environment. You will own the vessel's equilibrium, motion characteristics, and mooring dynamics from initial concept through full operational deployment. Your primary directive is to enforce rigid weight, center-of-gravity, and hydrodynamic margins to ensure that our conventional hull forms are natively pre-engineered to accept post-delivery nuclear payloads. By delivering survivable, highly reproducible, and modular hull designs optimized for extreme station-keeping, you guarantee absolute platform stability, eliminating buoyancy, mooring, and capsizing risk across the entire operational lifecycle. Primary Responsibilities - Command Seakeeping and Stability Architectures: Lead the analysis and validation of intact and damage stability matrices, ensuring the platform complies with strict international maritime codes and utility-grade uptime mandates. - Own Environmental Interaction Modeling: Direct advanced hull-wave interaction modeling, computational fluid dynamics (CFD) simulations, and model testing loops to predict platform behavior in extreme metocean conditions. - Enforce Rigid Hydrodynamic and Mass Margins: Establish and safeguard strict center-of-gravity (CoG) limits, weight growth margins, and buoyancy reserves to accommodate heavy nuclear containment structures without compromising marine safety. - Design Resilient Mooring and Station-Keeping Systems: Own the analytical design and dynamic simulation of station-keeping and mooring system architectures, ensuring the platform remains securely pinned across decades-long operational lifecycles. - Support Class and Regulatory Technical Submissions: Author the technical stability booklets, hydrodynamic reports, and safety-at-sea documentation required to clear classification society gates and statutory regulatory reviews. Qualifications - Bachelor’s or advanced degree in Naval Architecture, Marine Engineering, or a strictly related fluid dynamics engineering discipline. - 8+ years of experience specializing in marine hydrodynamics, stability engineering, or offshore mooring design for commercial vessels, semi-submersibles, or floating production assets. - Deep proficiency in specialized naval architecture software (e.g., GHS, MOSES, WAMIT, ANSYS AQWA) alongside an authoritative understanding of intact/damage stability regulations (e.g., ABS, DNV, IMO). - A precise, data-driven engineer who possesses total command over naval architecture physics, communicates technical risk with absolute clarity, and maintains analytical discipline under aggressive design schedules. Why this matters Every industry on Earth needs scalable, clean energy, and the ocean is the ideal place to unlock it. Joining Ocean Atomics means building real, lasting infrastructure — the kind that powers generations. The world needs abundant energy. Let's make it happen.
