Lead Software Engineer / Tech Lead

About HyperFi We’re building the kind of platform we always wanted to use: fast, flexible, and built for making sense of real-world complexity. Behind the scenes is a robust, event-driven architecture that connects systems, abstracts messy workflows, and leaves room for smart automation. The surface is clean and simple. The interactions are seamless and intuitive. The machinery underneath is anything but. That’s where you come in. About HyperFi We’re building the kind of platform we always wanted to use: fast, flexible, and built for making sense of real-world complexity. Behind the scenes is a robust, event-driven architecture that connects systems, abstracts messy workflows, and leaves room for smart automation. The surface is clean and simple. The interactions are seamless and intuitive. The machinery underneath is anything but. That’s where you come in. We’re a well-networked founding team with strong execution roots and a clear roadmap. We’re backed, focused, and delivering fast. We’re looking for a Lead Software Engineer to join early. Someone who thrives in fast-moving teams, values clarity and execution, and can help drive delivery while staying hands-on. You’ll be the glue that holds the team together — bridging frontend, backend, infra, and vendor pods — while still writing code every day. What You’ll Do Own the overall architecture for our core platform and integrations Drive key technical decisions across FE/BE/API/data/infrastructure Write production code in Python + React (and push for quality) Guide a team of senior engineers to milestone delivery — by unblocking and mentoring Establish best practices for modularity, observability, testing, and release Be the link between engineering, product, and delivery partners Work directly with the CTO and founders to shape the roadmap Tech Stack (So Far) Python (async-first, service-oriented) React + Next.js (FE) Terraform + GCP (infra-as-code) Databricks, Postgres, and message queues MCP + LLM orchestration How We Build Engineers come first: your time, focus, and judgment are respected Deep work > chaos: fixed cycles & cooldowns protect focus and keep context switching low Autonomy is the default: trusted builders who own outcomes, no babysitters Ship daily, safely: merge early, integrate vertically, ship often, use feature flags, and keep momentum Outcomes over optics: solve real problems, not ticket soup Voice matters: from week one, contribute, improve something, and shape how we build Senior peers, no ego: collaborate in a high-trust, async-friendly environment Bold problems, cool tech: work on complex challenges that actually move the needle Fun is part of it: we move fast, but we also celebrate wins and laugh together What We’re Looking For 8+ years shipping software end-to-end (startups or high-velocity teams preferred) Strong grasp of system design, event flows, and service boundaries Hands‑on experience delivering APIs, agentic apps, and UI features under pressure You know how to mentor senior ICs to drive product delivery You care deeply about momentum, pragmatism, and clean interfaces You see ambiguity as an opportunity to lead, not a reason to stall Confident English skills to collaborate clearly and effectively with teammates Bonus If You Have startup scars or scale‑up war stories Have worked across both B2B SaaS and infra‑heavy systems Can demo something you built (repo, sketch, hack — anything real) Location & Compensation Must be based in San Francisco, Las Vegas, or Tel Aviv Full‑time role with competitive comp Flexible hours, async‑friendly culture, engineering‑led environment #J-18808-Ljbffr SupportFinity™
