Lead Software Engineer (Java/Spring | FinTech)

About the Role

We are seeking a highly experienced, hands-on Lead Software Engineer to help drive a regulated financial platform into production.

This role combines technical leadership, hands-on development, production readiness, and release ownership. Approximately 50% of the role will remain focused on coding and code reviews, so we are looking for someone who is still deeply technical.

Key Responsibilities

• Lead the technical readiness and production launch of a financial platform.

• Write, review, and improve production-grade Java/Spring code.

• Own critical areas including payments, ledger accuracy, settlement, reconciliation, and transaction reliability.

• Drive technical reviews, architecture discussions, testing, and code quality standards.

• Implement strong engineering practices around idempotency, concurrency, data consistency, and financial correctness.

• Establish release gates and provide evidence-based go/no-go recommendations.

• Improve automated testing, CI/CD, observability, and production reliability.

• Mentor engineers and promote strong engineering standards across the team.

• Collaborate with compliance, risk, audit, product, and business stakeholders.

• Identify technical risks early and drive them through resolution.

Required Qualifications

• 5+ years of software engineering experience.

• 2+ years in a technical leadership role while remaining hands-on with development.

• Strong hands-on expertise with Java and Spring/Spring Boot or closely comparable backend technologies.

• Proven experience building, launching, or operating systems that move money or handle regulated data.

• Strong understanding of SQL, database transactions, locking, isolation levels, and data consistency.

• Experience with engineering best practices, automated testing, CI/CD, and production releases.

• Strong technical leadership, problem-solving, and stakeholder communication skills.

• Ability to balance delivery timelines with system reliability, security, and technical risk.
