Senior Backend Engineer

Position Summary

What we’re looking for

• TS-first backend: Expert in Node/Typescript services; bonus points for production Go.
• Systems & scale: Deep grasp of memory management, distributed systems, durable execution, and edge functions.
• Queues & state: Hands-on with Temporal (or equivalent durable workflows) and Redis at scale.
• Cloud & reliability: Comfortable shipping/operating in modern cloud environments with strong observability habits.
• LLM-aware: Familiarity with LLM integrations and their operational quirks is a plus.
• Product sense: You make pragmatic tradeoffs, communicate risk clearly, and choose designs that unblock the roadmap.
• Opinionated: Deep level of understanding of the technological landscape, making both high level system and granular code design decisions based on understanding rather than preference - diving deep on unknown patterns in order to build the best product.

Responsibilities

• Architect, build, and operate backend services that are fast, fault-tolerant, and easy to evolve.
• Define service boundaries, data models, and contracts that keep teams moving independently.
• Establish performance baselines and SLOs; design for durability and graceful degradation.
• Lead technical design reviews and mentor engineers across code quality, testing, and ops.
• Own critical systems: queue orchestration (Temporal), caching (Redis), and infra automation.
