Responsibilities

• Own several internal products in the HR and data analysis space.

• Build new features, integrations, and data sources as the products evolve.
• Design and improve data schemas, integrations, and data flows.
• Set up and maintain CI/CD, observability, structured logs, error alerting, and performance tracking.

• Use modern AI coding tools productively as part of the daily workflow.
• Keep products maintainable, understandable, and ready for future team members.

Requirements

• Experience taking prototypes or POCs into production-grade systems.
• Strong full-stack experience with TypeScript, React, and Node.js or other modern programming ecosystems.
• Working knowledge of PostgreSQL, including schema design, JSONB, migrations, indexing strategy, and data integrity.
• Experience with cloud PaaS deployments and CI/CD, especially GitHub Actions.
• Practical experience with observability: structured logs, performance monitoring, error alerting, and production troubleshooting.
• Experience integrating third-party APIs or other data sources.
• Good judgment when making technical decisions, especially around stack choices, refactoring, and maintainability.
• Comfort working without a dedicated platform team.
• Productive use of AI coding tools such as Claude Code, Cursor, or similar.

How we work

• Be clear about whether a POC, MVP, or production product is being built.
• Ship regularly in small, visible iterations.
• Diagnose before fixing.
• Test at a reasonable level without overcomplicating things.
• Avoid unnecessary processes and over-architecting.
• Treat the existing stack as a starting point, not a limitation.
• Document what matters so others can understand and build on the work.

What success looks like after 90 days

• Two products have moved from POC to MVP.
• Internal teams are using the tools instead of spreadsheets or third-party tools.
• Monitoring is in place and is being acted on.
• Apps are documented in their repositories, making it easier to onboard another engineer.
