Senior Platform Engineer

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space. The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits. With multiple launches planned through 2026 and 2027, we're Building Bigger to develop the solar system and become a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a groundbreaking Series C space startup, we’d love for you to apply. The Role Our enterprise software team builds the digital backbone that powers K2 Space’s satellite design, manufacturing, and mission operations. We develop tools that connect engineering, production, and mission control into a seamless ecosystem — enabling our hardware to get from concept to orbit faster than ever before. As we continue to grow, we’re looking for a Senior Platform Engineer on our Enterprise Information Systems team, you must possess strong technical skills and a sense of empathy for your fellow developers. You will work closely with other talented engineers, architects and senior stakeholders to design, implement, and deliver on our roadmap. Our Ideal Candidate Distills Kubernetes cloud networking (identity, routing, segmentation, exposure) into clear, lightweight abstractions that cut cognitive load for product teams Claims ownership of hard connectivity challenges end‑to‑end, including design, rollout, adoption, and lifecycle producing solutions with company‑wide impact Practices surgical precision in feature development, delivering high value while avoiding complexity that delays or bloats Delivers work permeated with excellence including readable code, automated tests, clear documentation, consistent maintenance, and polished observability Intuitively understands packet flow, service identity, and secure communication with a keen ability to simplify them Understands the importance of resilience and reliability in production operations and upgrades Responsibilities And Accountabilities Design and evolve self‑service connectivity abstractions enabling scoped segmentation, governed exposure, adaptive ingress/egress, and traceable traffic Own service identity trust (mTLS, cert automation, least‑privilege east‑west, governed egress) with broad coverage and low friction Engineer resilient traffic paths (timeouts, retries, circuit breaking, failure isolation) and harden them via chaos tests, automated remediation, and MTTR reduction Establish observability standards so end‑to‑end request path and applied policies are visible (source, identity, route, outcome, saturation, cost) across environments Provide approachable docs diagnostics (guides, diagrams, ‘why can’t this connect?’ flows) to shorten support loops Optimize performance cost (latency budgets, cross‑AZ transfer, IP consumption, LB efficiency) and act on anomalies Apply threat abuse modelling to connectivity surfaces (API exposure, egress, identity propagation) using industry principles while keeping solutions developer‑friendly Steward lifecycle and adoption including versioning, safe migrations, deprecations, usage telemetry, and proactive pruning of unused reso ...
