Software Engineer

Vestmark is building the AI-native future of wealth management technology. We are looking for early-career Software Engineers in Boston who are 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. This role is based out of the Boston office in the Seaport District. 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. What You’ll Do Build Agentic Systems • 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 Apply AI-Native Development Practices • 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 Contribute to Reusable Foundations • 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 Grow & Contribute to the Team • 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 What We’re Looking For Engineering Fundamentals • 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 at least one language, with willingness to use whatever the problem requires • Understanding of APIs, basic cloud concepts, and modern software delivery practices AI Fluency & Curiosity • 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 Problem-Solving Orientation • 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
