Senior AI Backend Engineer

Senior AI Backend Engineer About Klarity Klarity (YC S18) is the Enterprise Instinct platform. TL;DR: Series B, $91M raised, 7x growth last year. Enterprises still rely on consultants to figure out how they operate – months of work, millions spent, and outdated before the ink dries. We built a better way. Our AI discovers how work actually happens across every team and application, Structures it into a living Context Graph, and Improves it continuously. ServiceNow mapped 900+ processes in 9 days. DoorDash captured 3,800+ finance operations in 14 weeks, replacing a 2-year engagement. That's not a project. That's compounding intelligence. OpenAI, Google, DoorDash, and Stripe use Klarity to transform how they transform. We shipped GPT-4 document chat within 12 hours of OpenAI's API launch. Speed and quality aren't a tradeoff here – they're the standard. THE ROLE We're hiring Senior Backend + Applied AI Engineers to build the core systems that power Klarity's multimodal agents in real enterprise environments. This is a hands-on engineering role at the intersection of distributed systems and applied AI: you'll design and ship backend services that ingest messy real-world data, orchestrate model/agent workflows, enforce enterprise-grade security and deliver reliable outcomes at scale. You'll work closely with product, design, and other engineers to turn ambitious AI capabilities into production-grade features that Fortune 500 enterprises can depend on. We care deeply about engineering fundamentals (correctness, observability, security, performance) and equally about iteration speed - because in this space, only the teams who ship quality products & features at incredible velocity win. You'll set technical direction for critical subsystems and mentor engineers earlier in their careers - raising the bar for the entire team. Note: We do not require a CS or Engineering degree. We care about your ability to ship, your systems thinking, and evidence of strong execution - whether through production work, open-source contributions, research, or high-quality side projects. WHO YOU ARE - Backend engineer with sharp product judgment - You design and build services, APIs, data models, and infrastructure that are reliable, observable, secure, and fast. You can explain architectural tradeoffs as fluently as you can debate the right abstraction boundary. You optimize for outcomes - developer velocity, latency, correctness, uptime - and not just for elegance in the abstract. You've been the person teams turn to when a design review needs a tiebreaker. - Systems thinker with uncommon foresight - You see around corners. While solving today's stated requirements, you anticipate how services will need to evolve - functionally and non-functionally. You design for the future but build for the present, and you never let architectural dogma slow the team down. You've designed at least one system from scratch that other engineers now build on top of and is used in production at scale. You establish patterns and conventions that become team defaults. - Applied AI builder who ships to production - You're energized by LLMs, multimodal agents, orchestration protocols, and the messy work of making the entire AI stack reliable. You think instinctively in terms of evals, model regression tests, traceability, and exception handling. You've shipped multiple AI-powered features to production and have hard-won opinions about orchestration patterns, eval frameworks, and failure modes at scale. - AI-native developer across the entire SDLC - You wield tools like Cursor, Claude Code, and Copilot as extensions of your craft. You are extremely confident to run concurrent agents doing your chores reliably. You use AI to generate technical designs, scaffold APIs, draft schemas, write tests, and build migration plans. You've built custom workflows and internal tooling around AI-assisted development that others on your team have adopted. - Ship with velocity a ... (truncated, view full listing at source)
