Job Description

We are seeking an experienced Lead Developer to lead technical delivery for a team: hands-on coding, architecture alignment, and raising the bar on quality and operations. You will design and ship backend capabilities, partner on requirements and trade-offs, and help the team deliver reliably in production.

Responsibilities

- Design, implement, and review features and APIs (services, integrations, data access).

- Own reliability for services you touch: correctness, performance, observability, and safe releases.

- Work with the team on architecture for new capabilities and on improving existing systems (database schema, caching, deployment, operational runbooks).

- Partner with product and other engineering teams on requirements, estimates, and technical trade-offs.

- Review code, clarify design, and mentor engineers informally; contribute to a culture of quality and learning.

- Identify and drive process improvements: clearer contracts, better tests, CI/CD hygiene, and reduced operational toil.

- Create and maintain technical documentation where it helps onboarding and operations.

Qualifications

- 4+ years of professional experience shipping production backend services in Java (e.g. Spring Boot) or an equivalent JVM stack; comfortable with REST APIs, validation, auth integration (e.g. OAuth2 / JWT), and common Spring patterns.

- Data stores — solid PostgreSQL: schema design, migrations (e.g. Flyway or similar), indexing, transactions, and debugging slow queries.
