Senior Java Software Engineer

Vestmark is building the AI-native future of wealth management technology. We are looking for a Senior Java Software Engineer who is serious about AI-assisted development, curious about how software engineering is changing, and ready to do real work on systems that matter. You will not be handed a ticket queue. You will be expected to think, build, and grow quickly in an environment where AI fluency is the baseline, not the aspiration.

Vestmark is a leading provider of wealth management solutions and services that enable financial advisors and institutions to efficiently manage and trade their clients' portfolios using a purpose-built SaaS ecosystem. With over $2 trillion in assets and 5+ million accounts, we are a trusted partner to some of the largest and most respected players across the wealth management industry.

• Contribute to the design and delivery of agentic systems: workflows where AI plans, executes, and iterates toward outcomes rather than simply responding to requests
• Build and ship production-quality solutions as part of a squad working on real efficiency and automation problems with direct business impact
• Participate in the full delivery lifecycle: design discussions, development, testing, deployment, and iteration

• Use AI-assisted development tools, including code generation, prompt engineering, and agentic frameworks, as a standard part of your daily workflow from day one
• Learn and apply the team’s standards for building AI-native systems: state management, observability, non-determinism, and inference cost awareness
• Engage with testing and validation approaches specific to adaptive systems where behavior is not fully deterministic

• Create clean, testable, maintainable solutions that strengthen the team's shared foundation; treat code quality as a direct contribution to everyone who touches this codebase after you
• Apply the principle “fix the process, don’t automate the broken one”: understand the problem deeply before proposing a solution
• Participate in code reviews as both a reviewer and a recipient; treat both as learning opportunities

• Engage actively in design reviews and architecture discussions, asking questions and developing your point of view over time
• Take feedback seriously and apply it quickly; growth velocity matters here as much as current skill level
• Contribute to the growth and development of our core values:
  We Before Me, Positive Energy, Knowledge Explorer, and Own It

• Solid foundational knowledge of software engineering: data structures, algorithms, system design basics, and how production systems behave under real-world conditions
• Ability to build and deliver working solutions in Java
  , with willingness to use whatever the problem requires
• Understanding of APIs, basic cloud concepts, and modern software delivery practices

• Genuine, hands-on familiarity with AI-assisted development tools: you use them regularly, you have opinions about them, and you are actively developing your practice
• Curiosity about agentic systems: how AI can plan, take action, and iterate toward outcomes in multi-step workflows
• Awareness of where AI tooling is heading and a desire to stay current as it evolves rapidly

• Ability to engage with ambiguous problems: ask good questions, break the problem down, and propose a reasonable approach before jumping to a solution
• Comfort working on problems where the full solution isn’t defined upfront
• Attention to the business context of the work: understanding why something matters, not just what needs to be built
