Job Description

About you
You're excited to work on a mature, customer-facing product where your contributions have immediate impact. In this role, you'll own features end-to-end across a modern full-stack environment built with Java 21, Spring Boot, and Angular, delivering scalable, well-tested solutions that support real users and business-critical workflows.

You'll join a collaborative product development team where ownership, quality, and communication are highly valued. We're looking for someone who is comfortable working within an established codebase, can confidently participate in Agile ceremonies and client-facing discussions, and proactively communicates risks, complexity, and timelines to help the team deliver successfully.

• 8+ years of professional software development experience, with meaningful backend time in Java using Spring Boot or a comparable framework.
• Solid, working knowledge of Java 21 and modern Spring Boot patterns: dependency injection, REST controllers, service layers, and configuration management.
• Hands-on Angular experience (v14+ to  Angular 19 strongly preferred), with practical, production use of RxJS for reactive state and data flows.
• Comfortable writing and reasoning about SQL against PostgreSQL, joins, indexing, and query fundamentals.

• Working familiarity with Redis for caching or pub/sub patterns in production.
• Hands-on experience with AWS ( S3, ECS, CloudWatch).
• Strong testing discipline, writes and runs comprehensive unit/E2E tests on critical business logic before handing off to QA.
• Proven ability to estimate complexity accurately on backend features, flagging scope changes early.
• Highly self-managed, ability to navigate large existing codebases and resolve ambiguity independently.
• Excellent communication skills in English, required to work effectively with our US-based team and stakeholders.

You will be accountable for the following responsibilities:

• Design, build, and debug new product features end-to-end, across the backend API layer and the Angular frontend, within an established monolithic codebase.
• Develop and maintain RESTful APIs in Java 21 / Spring Boot, backed by PostgreSQL (MyBatis) and Liquibase for schema changes.
• Implement and maintain Redis-based caching strategies for performance and session management.
• Build reactive Angular 19 components using RxJS and client-defined UI frameworks, ensuring consistent UX.
• Write E2E and unit tests focused on critical business logic.
• Work with AWS (S3, ECS, CloudWatch, Bedrock) for storage, deployment, observability, and AI integrations.
• Proactively communicate when a feature's complexity or scope exceeds initial estimates, before committing to a delivery timeline.
• Actively participate in Agile ceremonies and weekly client-facing meetings.
• Partner with peer engineers to shape workflows and maintain code quality across the team.

Qualifications

• Proficiency in Java 21 and Spring Boot.
• Hands-on experience with Angular 19, RxJS, TypeScript.
