Job description
About the Role
We’re looking for a hands-on Tech Lead to guide the technical direction of AIR, our AI-powered interviewing platform. AIR handles real-time candidate interviews, ATS integrations, AI-generated scoring, and customer-facing workflows used by enterprise hiring teams.
As the Tech Lead, you will own the technical foundations of AIR, support a growing engineering team, and ensure we ship high-quality features with reliability and speed. You will also play a critical role in stabilizing and expanding our integrations ecosystem as we scale.
This is a high-impact role on a product that is central to the company’s strategy.
What You’ll Own
Technical Leadership & Architecture
- Define, communicate, and maintain AIR’s technical architecture.
- Lead technical decision-making and support engineers through complex problem-solving.
- Reduce system-level risks, eliminate single points of failure, and improve maintainability.
- Guide the team through ongoing modernization, integration scaling, and performance improvements.
Hands-On Development
- Write high-quality, production-ready code.
- Own complex backend workflows, infrastructure changes, and service integrations.
- Partner closely with the Product team to scope, sequence, and deliver features.
Reliability, Code Quality & Deployment
- Oversee code reviews, enforce engineering standards, and improve development workflows.
- Own the end-to-end deployment pipeline, including CI/CD, rollback strategy, and stability.
- Introduce tooling and automation to reduce regressions and improve team productivity.
ATS + External Integrations
- Lead the design, maintenance, and scaling of ATS integrations.
Team Collaboration & Mentorship
- Provide technical mentorship to a small but fast-moving engineering team.
- Collaborate cross-functionally with Product, Design, QA, and AI Engineering.
- Help create a culture of high ownership, learning, and engineering excellence.
What You Bring
Required
- 5+ years of experience as a senior engineer; 1–2 years in a tech lead or staff-level role preferred.
- Strong proficiency in full-stack development (Node/TypeScript, React, or similar).
- AI-native development mindset — highly efficient with AI-enhanced coding tools (e.g., Cursor) to accelerate architecting, implementation, debugging, and tech debt cleanup.
- Experience designing and scaling production services with real users.
- Deep understanding of API integrations, webhooks, async workflows, and data mapping.
- Strong system architecture skills with a focus on reliability and maintainability.
- Comfort owning CI/CD pipelines and production deployments.
- Skilled in code reviews, team technical leadership, and mentoring.
- Ability to balance speed and quality in a startup environment.
Nice-to-Have
- Experience with AI/ML-driven products (LLM orchestration, model evaluation).
- Experience with ATS systems or HR tech integrations.
- Familiarity with security best practices, SOC2 environments, and user permissions/RBAC.
- Prior involvement in early-stage startups or rapid-growth teams.
What Success Looks Like in the First 90 Days
- You understand AIR’s architecture end-to-end and strengthen critical workflows.
- You take ownership of deployments and reduce operational risks.
- The engineering team is unblocked and moving confidently with you as technical anchor.
- ATS integrations are stable, monitored, and easier to maintain.
- Velocity remains strong even as we introduce more structure and reliability.
Why Join Us?
- You’ll lead the technical foundation of one of the fastest-moving AI hiring products.
- You’ll work with a tight-knit team who values autonomy, impact, and building things that matter.
- You’ll have real ownership: architecture, integrations, delivery, and engineering culture.
- You’ll shape how AI transforms hiring — from interviews to insights to recruiter workflows.
