Overview

We're looking for a Senior Java Software Engineer to own the backend engineering for a critical platform — building modular services, migration scripts, data validation tooling, and APIs from the ground up. This role sits at the intersection of enterprise Java development and cloud-native architecture, leading a phased rollout strategy with zero-downtime cutover from legacy to new systems while maintaining data integrity across production environments.

Key Responsibilities

• Architect, develop, and maintain scalable Java backend services using Spring Boot
• Design and implement database migration scripts for production cutover between legacy and new systems
• Design and implement secure, well-documented RESTful APIs and service interfaces
• Collaborate with front-end developers (SvelteKit stack)
• Write comprehensive unit and integration tests to ensure code reliability
• Participate in code reviews and promote clean code principles
• Support cloud-native practices including containerization, configuration management, and observability
• Ensure service-level security, performance, and resilience
• Contribute to sprint planning, ticket breakdowns, and estimation
• Maintain technical documentation for migration procedures and system architecture

Requirements

• 5+ years of professional experience developing applications with Java and Spring Boot
• Strong PostgreSQL experience — complex queries, schema migrations, performance tuning, and production data operations
• Proven experience designing and building RESTful APIs and microservice architectures
• Hands-on experience working in AWS cloud environments
• Familiarity with containerization (Docker, Kubernetes) and DevOps practices
• Hands-on experience with AI-assisted engineering tools (e.g. Claude Code, Cursor, or similar) — required
• Strong sense of ownership, quality, and accountability
• BS in Computer Science, Engineering, or equivalent practical experience
• Good level of spoken and written English: able to communicate technical topics effectively across distributed teams
• Working hours: Pacific Standard Time - Full time

Preferred Qualifications

• Background in regulated or compliance-driven systems is a plus
• Exposure to event-driven architectures and message queues
• Experience with data comparison/validation frameworks (e.g. dbt or similar)
• Familiarity with monitoring/observability tools (e.g. Datadog)
• Experience with MongoDB as a secondary datastore

Conditions

• Fully remote role with a flexible schedule
• Compensation in USD via a convenient payment method
• Direct collaboration with founders and fast decision-making
• High level of ownership and the opportunity to lead architecture-driven transformations
