About OrbitShift
At OrbitShift, we are building the world's first AI-native Sales Operating System, trusted by enterprise teams to accelerate their GTM motion. Our multi-agent AI system enables actionable account insights, RFP response generation, targeted nudges, and sales content. Backed by Peak XV (formerly Sequoia Capital), Stellaris Venture Partners, and other marquee investors, we are a fast-growing, 3-year-old startup with a team from Amazon, McKinsey, IIT, and Stanford.

Role Overview
As an SDE 3, you design and own systems that span a team or multiple teams. You apply SOLID and design patterns with judgment — knowing when to use them and when not to — and you design for long-term evolution rather than just the immediate requirement. You drive trade-off, reliability, and operational conversations unprompted, remain deeply hands-on in code,



and act as a technical multiplier for the engineers around you.

Key Responsibilities
Architect Systems: Design multi-service systems with clear ownership boundaries — making robust choices on storage, partitioning, caching, sync vs. async paths, and API contracts, and reasoning about how the design evolves as scale grows 10× or requirements shift
Raise the LLD Bar: Handle larger, less-bounded problems. Model cleanly, justify pattern choices against alternatives, and design plugin/registry-style extensibility where it earns its place. Handle concurrency, thread-safety, and performance under non-trivial load deliberately
Own Hands-On Delivery: Write production-quality code for core platform components and lead complex features end-to-end, from design through deployment and observability.
Drive Trade-offs & Reliability: Lead deep trade-off analysis (consistency models, cost vs. latency), define SLOs, identi
