Full Job Description

đź“‹ Description

  • • Hands-on product building. Design and implement features end-to-end across frontend, backend, and AI layers. Actively writing production code and shipping real systems, not just specs and diagrams.
  • • Own the technical architecture. Define and execute the technical vision and multi-year roadmap for our application platform (Next.js/React frontend, containerized Python and Node services), ensuring rapid iteration while scaling reliably with enterprise demand.
  • • Build AI-heavy product experiences. Design and operate the systems behind document processing, chat, and analytics — spanning workflow orchestration (Temporal), streaming pipelines, vector search, and LLM inference paths; balancing latency, quality, and cost.
  • • Build for security and compliance. Ship features and services that meet SOC 2 requirements from day one: multi-tenant isolation, least-privilege access, audit logging, and encrypted data flows across storage, database, and AI providers.
  • • Establish engineering excellence. Set and uphold standards for code quality, testing, deployment pipelines, observability, and incident response; mentor engineers to foster a culture of reliable, maintainable, high-velocity development.
  • • Cross-functional collaboration. Partner with product, design, and enterprise customers to translate requirements into pragmatic, well-crafted solutions that ship quickly and hold up under real usage.

🎯 Requirements

  • • Hands-on technical leadership. 7+ years building and scaling mission-critical software, with demonstrated experience architecting products and systems from the ground up.
  • • Full-stack fluency. Production experience across modern web frontends (React/Next.js or equivalent) and backend services (Python and/or Node.js), including API design, data modeling, and building for performance and reliability.
  • • Systems and data expertise. Comfort operating Postgres at scale (RDS, Supabase, or self-managed), Redis, and workflow/message systems (Temporal, SQS, Kafka), and ideally vector databases or LLM serving infrastructure.
  • • Product and AI sensibility. Familiarity building AI-powered features — LLM integration, retrieval, agents, or streaming interfaces — with a focus on real user value.
  • • Security-first mindset. Practical experience building within SOC 2 (or similar) compliance programs, including access control, secrets handling, and multi-tenant data isolation.

🏖️ Benefits

  • • $200K – $300K base salary
  • • Offers Equity
  • • Total rewards package including base salary, equity (stock options), and benefits
