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

• Demonstrated ability to learn quickly and independently: you don’t wait to be taught everything
• Receptive to feedback and able to apply it quickly; the expectation is continuous improvement, and you take that seriously
• Evidence of intellectual curiosity beyond coursework: personal projects, open source contributions, self-directed learning in AI or systems engineering

• You engage with the problem before you engage with the solution; you ask why before you ask how, and you want to understand what you're building and whether it's the right thing to build
• You form a point of view on what you're building and why it matters; you don't treat requirements as fixed inputs but as the starting point for understanding the problem

• Hands-on experience with agentic frameworks, LLM APIs, or workflow orchestration tools, whether through coursework, personal projects, or early professional work
• Experience with AWS or equivalent cloud environments, even at a basic level
• Background or coursework in financial services, mathematics, or quantitative disciplines
• A project, contribution, or body of work you can speak to in depth: something you built, something that broke, and what you learned from both

• Join a team that is building AI-native systems in production, in a domain where the business consequences of this work are direct and measurable
• Develop real AI engineering skills in an environment where those practices are the established standard
• Work alongside Principal and Senior Engineers who are among the best in this space and who are invested in your growth

• B.S. in Computer Science or equivalent work experience; M.S. a plus
• 7+ years of professional software engineering experience with a focus on Java development; strong internship experience or personal project work considered
• Backend Development: Strong expertise in Java and related frameworks such as Spring or Spring Boot. Experience with modern architecture and related design patterns. Strong algorithmic and object-oriented design skills. Recent experience with RESTful API design and implementations is preferred.
• Architecture: Proven experience in designing and implementing scalable and resilient software architectures, with an emphasis on Java-based solutions.
• Data Management: Strong knowledge of both relational (e.g., MySQL, SQL Server, PostgreSQL) and NoSQL databases (e.g., DynamoDB, MongoDB).
• Troubleshooting: Proven experience in performing in-depth root cause analysis to identify the underlying causes of software issues, whether they are related to the application, system environment, or user input. Knowledge of application performance monitoring (APM) tools such as Dynatrace or Splunk is desired.
• Demonstrated AI tool fluency
