## About the Role

* Strong engineering fundamentals. Design patterns, core OOP principles (inheritance, polymorphism, composition), and algorithmic thinking - how you think about the design and structure of code matters more than which language you know.
 * Experience with Java/Kotlin/JavaScript/TypeScript. Strong professional experience with at least one of these languages.
 * Data modeling and database design. Strong experience designing relational schemas and working with relational databases (PostgreSQL preferred), including thoughtful decisions about data structures, relationships, integrity, performance, and how models evolve over time.
 * Wealth management or wealth-tech experience. Closely adjacent fintech works too - it shortens the distance between a client's problem and a working solution, given the specialized data and workflows we work with today.
 * Communication and commercial instincts. Comfortable representing the team in front of clients and business stakeholders.
 * Composure under pressure. Comfortable juggling multiple concurrent priorities in a fast-moving, early-stage environment.
 * No heroics, just engineers who make each other better. Generous with their knowledge, quick to help a teammate, and more focused on the outcome than the byline. We build and ship as a team.
 * Genuine enthusiasm for AI-enabled engineering. You don't need deep experience with AI coding agents yet, but you should be comfortable with agents writing code alongside you, curious about how they're changing the craft.
 * Real passion for AI. Evidenced by more than professional interest-be it through side projects, independent research, or hands-on experimentation.

## Description

* Full-stack development. Build across our web and workflow products - front end, back end, and increasingly the systems that support AI driven workflows.
 * Solution and system architecture. Help decide how services, data, and agents fit together - not just implement someone else's design.
 * Data modeling and database design. Design the schemas, relationships, and data structures that underpin our platform-translating complex wealth-management concepts into data models that are accurate, extensible, and built to evolve.
 * AI agents for real work. Build agents that handle multi-step business workflows and process unstructured documents.
 * Build AI-forward by default. You'll treat agentic tooling as a genuine force multiplier, not a novelty - writing specs that AI agents implement, and reviewing or directing their output.
 * Operate as a business-focused technologist. You'll work closely with clients and commercial stakeholders as a regular part of the job, not an occasional one - some engineers act as forward-deployed engineers today. Clear communication and product sense are as much a part of this role as the code.
