Job Description
Job Title: Software Engineer (Zara)
Job Type: Full-time
Location: Remote (Must overlap PST timezone at least 6-8 hours)
The Role
This is a high-ownership fullstack role where you’ll contribute to — and grow into owning — core product surfaces end-to-end. You’ll primarily work on building and improving Zara, our AI Recruiter agent, shaping how it operates, scales, and delivers value to users.
What You’ll Own
- Contribute to the design and development of end-to-end fullstack systems powering core product workflows.
- Build clean, scalable backend services and APIs with clear contracts and ownership.
- Develop high-quality, performant frontend interfaces that ship directly to users.
- Participate in data modeling and database performance optimization (schema design, query tuning, maintainability).
- Collaborate closely with product and design to translate ambiguous requirements into shipped systems.
- Uphold engineering quality through code reviews, testing, and continuous improvement.
- Help debug and resolve production issues; contribute to improving reliability and observability.
- Learn to make pragmatic tradeoffs between speed and correctness in a fast-moving AI lab environment.
Preferred Background
- Experience building or contributing to production fullstack systems (internships, projects, or professional experience).
- Strong TypeScript fundamentals across frontend and/or backend.
- Familiarity with backend development using Node.js (NestJS is a plus).
- Experience building user interfaces with React or similar frameworks.
- Understanding of relational databases such as PostgreSQL and basic data modeling principles.
- Familiarity with RESTful APIs and how systems communicate at scale.
- Exposure to cloud platforms like AWS (or similar).
- Awareness of modern architectures (microservices, serverless, or event-driven systems).
- Curiosity, ownership mindset, and strong attention to detail.
Nice to Have
- Experience with CI/CD, infrastructure as code, or DevOps workflows.
- Experience building or contributing to production-grade systems.
- Exposure to AI-adjacent, data-heavy, or ML-powered products.
- Experience working in fast-paced, ambiguous environments (startup, lab, or similar).
