Mobena • ,

11d • $180,000 - $220,000 • Remote

About The Position

Mobena is hiring a hands-on Head of Frontend Engineering to take ownership of its frontend and lead the existing product toward general release in March 2027. The role begins as the initial frontend engineering team of one and will write code every day while independently leading frontend engineering and setting technical direction in partnership with the CTO.

Mobena is a planning system for wealthy families that brings income tax, estate planning, and financial planning into one model. The product models families’ trusts, entities, ownership, assets, and obligations over time, helping advisors compare planning decisions, understand tax consequences, and explain results to families. The frontend must make complex financial information usable without adding interface complexity.

The Head of Frontend Engineering will own the frontend codebase, build and improve user-facing features, evolve the frontend architecture and technology stack, and coordinate with the CTO on APIs and integration with the financial engine. The role will establish standards for testing, performance, accessibility, design systems, code review, and releases, while maintaining an active product used by advisors for testing. The position will also help determine when to expand the frontend team and whom to hire.

The role reports to the CTO and works directly with the CEO and Head of Product Delivery. It is remote within the United States, with East Coast working hours.

Requirements

• At least 8 years building production web applications, or equivalent experience.
• Deep expertise in React and TypeScript, with several years as a lead or senior frontend engineer.
• Experience working on a small team and improving engineering standards through collaborative code review and architectural decisions that are explained rather than imposed.
• Experience building data-dense web interfaces, such as grids, multi-level forms, charts, side-by-side comparisons, and printable reports.
• Daily use of AI coding tools; ability to work quickly with them and recognize where their output is wrong.
• A record of improving an existing codebase without a rewrite that stops the business.
• Product judgment and independence, including experience working closely with designers and users, distinguishing user requests from underlying needs, explaining pushback, and raising decisions outside one's area with a recommendation.
• Authorization to work in the United States; visa sponsorship is not available.

Nice To Haves

• WealthTech or tax technology experience, including software for financial advisors, wealth managers, CPAs, or estate planners in financial planning, portfolio reporting, tax preparation, tax planning, or estate planning.
• Familiarity with advisors’ daily work and the ways software can slow them down.

Responsibilities

• Own the frontend codebase as the initial frontend engineering team of one; build and ship UI components, screens, and features, fix bugs, and turn advisor feedback into improvements.
• Manage frontend application architecture and code quality, and collaborate with the CTO to choose and evolve the frontend technology stack as the company scales.
• Work with the CTO to define interface needs, frontend state and results flows between the frontend and core engine, and division of implementation work.
• Build family and ownership workflows, a forecasting grid, scenario comparisons, income-tax and estate views, document review, and reports that advisors can use with families and export to PDF.
• Plan and deliver changes that lead the existing frontend to general release without disrupting advisors who are testing it.
• Establish testing, performance, accessibility, design system, code review, and release practices, and serve as a senior technical resource for the team.
• Help determine when to hire the next frontend engineer and participate in deciding whom to hire.

Benefits

• Bonus eligible.
• Eligible to participate in the employee equity pool.
• Opportunity to make a significant contribution at a very early stage of a fast-growing startup.
