• Collaborate with distributed teams while maintaining strong individual ownership
• Contribute across the full Agile development lifecycle

Required Qualifications

• Bachelor’s degree in Computer Science, Engineering, or related field
• 9+ years of hands-on Java development (Spring Core & Spring Boot)

• Strong hands-on coding ability with the ability to explain and defend technical decisions
• A self-starter mindset with a high level of ownership and accountability
• Ability to take requirements and deliver solutions end-to-end without handholding
• Strong problem-solving skills and sound architectural judgment

Work Structure

• Part-time engagement (~20 hours/week)
