We’re hiring a Principal Software Engineer to own the technical direction of a major part of our platform, such as our data foundation, our cloud platform, or the intelligence we’re building into the product. Several work streams will build on the architecture you set, and you’ll keep shipping features alongside the team.
You’ll report directly to the CTO and work with product, investments, and company leadership on where the platform goes next.

• Own the architecture of a major part of our platform
  , setting the direction several work streams build on and carrying it through over years, including what to retire.
• Build across the stack
  , shipping features and services alongside the team, plus the prototypes, reference implementations, and hardest parts of the systems you design.

• Make the technology and build-versus-buy decisions that commit us for years
  , weighing cost, risk, and what our team can operate.
• Set the bar for architecture, security, and data correctness across work streams
  , in a regulated financial-services business where every number we show an advisor has to be right and auditable.
• Develop other senior engineers
  , using design reviews, pairing, and direct mentoring so other engineers can make these calls without you.
• Bridge engineering and the investment business
  , becoming the engineering voice our investment and advisor-facing teams seek out on domain and regulatory questions.

• Extensive experience building and evolving production systems
  , typically 12+ years, including setting the architecture for a major product or platform area that several teams built on.
• A track record of setting technical direction without formal authority
  , with proposals others adopted and decisions you saw through for years.
• Deep, demonstrated expertise in at least one area
  , whether cloud architecture and infrastructure on AWS or a comparable cloud, agentic software development where agents do production engineering work under guardrails and evaluation, or building AI capabilities into a product platform.
• Broad architecture range across back end, front end, data,…
