About the role
- We are seeking a hands-on Staff Software Engineer who thrives in building from 0‑1 and driving execution, directly contributing production-level systems across the entire stack while shaping our core product foundation.
- You will collaborate closely with the founding team to architect, build, and ship the features and services that power F2's AI-driven enterprise analytics platform from user-facing interfaces to the backend systems and AI workflows behind them.
Responsibilities
- 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.
- 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
- 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.
- 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.
- Engineering, Product, Design (EPD)
- Own the technical architecture.
Requirements
- 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.
- 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.
- Execution-driven mindset. You thrive in environments where you own systems end-to-end, iterate rapidly, and deliver production-ready solutions
- and you measure success in shipped impact, reliability, and user outcomes.
- Passionate builder who enjoys solving complex, ambiguous problems across the stack and iterating toward clear, impactful goals.
Compensation
- The total rewards package at F2 includes base salary, equity (stock options), and benefits.
