Note: The job is a remote job and is open to candidates in USA. Zafhires is a fast-growing B2B data and AI platform that assists go-to-market teams in identifying and converting their ideal customers. The Senior Full-Stack Developer will be responsible for building and shipping product features, contributing to the AI copilot, and owning cross-cutting initiatives across the full stack.
Responsibilities
- Flow Pilot — our AI-powered copilot product built on LangChain/LangGraph. You will be adding new tools and agents, making it smarter, giving it more access and knowledge, and shaping its responses. This is the primary near-term focus
- Client-facing product features — anything that touches the customer experience: search filters, analytics pages, data export, enrichment pipelines, and more
- AI-powered automation — building sequences, triggers, and pipelines that help customers close more deals with less manual effort
- Architecture and technical design — contributing to architecture review, writing design docs, and owning technical decisions in your domain
- Code reviews — reviewing teammates' code and having yours reviewed. High quality bar is a core part of the culture
Skills
- 7+ years of professional software engineering experience
- TypeScript — expert level, used across the full stack
- AWS — production deployment experience
- AI tools and LLMs — you are actively using AI in your development workflow today. If you are not all-in on AI, this is not the role for you
- Ability to work independently with ambiguous requirements — you can take a loosely defined problem, structure it, and deliver something real
- Full-stack capability — back end and front end, not a specialist in one
- Strong communicator — you will proactively flag blockers, set up meetings when you need something, and not wait to be told what to do
- LangChain / LangGraph experience — directly relevant to Flow Pilot work
- Node.js — recently added to our stack
- Experience at a startup — you understand what it means to own things in a small team
- Data structures and algorithms proficiency — you will be tested on medium to hard level problems
- PostgreSQL or similar SQL database in production
- Experience with CRM API integrations (Salesforce, HubSpot, MS Dynamics) — helpful but not required for this role
