We are seeking a highly experienced Senior Software Engineer with approximately 10+ years of hands-on software development experience building production-grade systems.

The ideal candidate has spent the last ~2 years deeply engaged in AI-augmented development (“vibe coding”), using LLM-based coding tools, agent-driven workflows, and MCP-style multi-agent systems and posses hands-on Java programming skills and advanced knowledege of Spring.

This is a deeply hands-on individual contributor role focused on shipping high-quality software at scale using both traditional engineering expertise and modern AI-native development practices.

Key Responsibilities

Hands-on Software Development

• Design, implement, and maintain high-quality production code across backend and distributed systems

• Own complex feature development end-to-end, from implementation through production deployment

• Debug, troubleshoot, and resolve issues in large-scale production environments

AI-Augmented Development (Vibe Coding / MCP Systems)

• Use AI to deliver robust, maintainable, and fully tested software

• Use LLM-based tools and agent workflows daily to accelerate coding, refactoring, and debugging

• Work with MCP-style agent systems to:

  • Generate and iterate on production code

  • Automate test creation and validation

  • Support debugging and root-cause analysis

  • Improve code review cycles and refactoring speed

• Continuously evolve personal development workflows using AI-native tooling

Code Quality & Engineering Excellence

• Deliver robust, maintainable, and fully tested software

• Improve testing practices, CI/CD workflows, and developer efficiency

• Identify and fix performance, reliability, and scalability issues in existing systems

Technical Collaboration

• Collaborate closely with engineers and product teams to deliver features iteratively

• Participate in code reviews and provide strong technical feedback

• Act as a high-seniority IC contributor embedded within engineering teams

Requirements

• 10+ years of hands-on software engineering experience

• Deep experience building and maintaining production systems at scale

• Recent (2+ years) hands-on use of:

  • AI coding assistants (LLM-based IDE tools, copilots, agent frameworks)

  • Multi-step agent workflows (MCP-style or equivalent systems)

  • Prompt-driven development, debugging, and refactoring workflows

• Strong track record of shipping complex systems in fast-moving environments

Technical Skills

• Expert-level coding ability in Java, Spring

• Strong experience with backend systems, APIs, and distributed systems

• Strong experience in system design

• Experience with AWS cloud services (production-grade environments)

• Strong experience with PostgreSQL (data modeling, performance tuning, querying)

• Strong understanding of cybersecurity standards and best practices (e.g., secure coding, OWASP principles, authentication/authorization, data protection in distributed systems)

• CI/CD pipelines, automated testing, and production debugging

• Comfortable operating in AI-augmented development environments on a daily basis

Nice to Have

• Experience with financial systems, fintech platforms, trading systems, payments, or other regulated financial environments

• Experience with developer productivity tools or internal engineering platforms

• Exposure to high-scale SaaS or distributed enterprise systems

• Experience training and experimenting with autonomous coding agents or AI workflows

• Contributions to automation, tooling, or engineering efficiency improvements

Mindset & Traits

• Strong individual contributor who excels at execution and delivery

• Deep technical curiosity and strong coding craftsmanship

• Comfortable working in rapidly evolving AI-driven development environments

• Strong bias toward shipping working software quickly and iteratively

• Uses AI tools as a core part of daily engineering practice, not as an add-on
