You’ll collaborate closely with product managers, designers, and other engineers in a fast-paced, highly agile startup environment.
What You’ll Do
Design, develop, and maintain core platform features across the frontend and backend
Contribute to technical decisions around architecture, scalability, and reliability
Collaborate with product, design, and QA teams to deliver seamless user experiences
Write clean, reusable, and testable code (unit, integration, and E2E testing)
Participate in code reviews, sprint planning, and daily standups
Help optimize platform performance, security, and data integrity for global use
Contribute ideas to improve platform usability, automation, and developer workflows
Tech Stack We Use
Frontend: React, TypeScript, Next.js
Backend: Node.js, Python, Express, PostgreSQL, REST APIs, GraphQL
DevOps: AWS, Docker, CI/CD (GitHub Actions), Kubernetes (bonus)
Other: Jira, Git, Figma, Notion
What You’ll Bring
3–5 years of experience in full stack software development in SaaS or enterprise environments
Proven experience with modern JavaScript frameworks (React/TypeScript) and backend services (Node.js or Python)
Experience working in fast-paced, early-stage startups and agile teams
Strong understanding of RESTful services, relational databases, and API design
Comfort working in a distributed, async-first culture
Ability to write maintainable, scalable, and secure code in a high-growth environment
Excellent communication and cross-functional collaboration skills
Nice to Have
Experience building HRIS, global payroll, or compliance-driven platforms
Exposure to cloud platforms (AWS preferred)
Experience working with authentication/authorization (OAuth, SSO, etc.)
Familiarity with internationalization (i18n), role-based access control, or GDPR compliance
