About Our Company

Backed by two Fortune 300 firms, Brillian is a technology company focused on helping small to medium sized business owners achieve their goals and the trusted financial institutions that want to better service them. Brillian is a fast-moving, mission-driven team that's building something genuinely new and beginning a roll out to a million SMB owners in 2026. If you want your work to matter and your expertise to have real impact, you'll fit right in here.

Small to medium sized business owners are the primary engine of wealth creation in the modern economy. The asset they build — their business — is almost always their largest, most valuable, and most consequential financial holding. Yet the entire financial services infrastructure — advisors, banks, wealth managers, planning tools — was built around personal assets. The infrastructure to serve the most important asset was never built.

Brillian doesn't ask advisors, banks, or owners to work harder or learn something new. It fills the structural gap that was always supposed to be there — giving everyone in the ecosystem continuous visibility into the business, and a system for acting on what they see.

About

The Role

We are seeking a gifted, frontend software engineer to help support and grow our financial platform offerings. This is a significant opportunity to be a founding member of a growing team and help shape the way we develop, deploy, and operate production quality systems. In this role, your work will make a significant impact on our customers, stakeholders, and ability to continue to scale.

We need someone with significant experience building for the web, strong consumer product instincts, and the ability to work independently across teams.

Why Our Company?

Our engineers love building products, emphasizing efficiency and developer happiness. We deploy at-will, many times a day, coordinated via Slack, Git Hub, and Linear. As a remote-friendly team, we will always prefer asynchronous processes. As a result, our morning standup is the only recurring meeting and we Write Things Down™. Through collaboration, we prioritize the best answer — regardless who comes up with it — and believe "done" is better than "perfect."

We want to work with curious, self-motivated engineers who enjoy learning new technologies. So, instead of looking for people with "X years doing Y," we're glad to find those with opinions on a variety of languages and approaches. We're excited to know there's always more to learn; if you feel the same, let's work together!

We currently use NextJS with Graph

QL/Relay on the frontend and use Elixir/Phoenix, Python, INTERCAL, and NodeJS to power our backend and AI infrastructure. Our core systems store data in Postgre

SQL. We deploy on Google Cloud, provisioned through Terraform.

What You'll Do

• Leverage Type Script+React, Relay, INTERCAL, and Graph
  
  QL to build beautiful user interfaces and experiences.
• Shape frontend architecture and UI standards, guide technical decisions from state management and component structure to evolving our internal design system, refining shared patterns, and ensuring our interfaces remain consistent, accessible, and scalable across the platform.
• Support existing products and features, while helping design and build new ones.
• Communicate regularly with other stakeholders, partners, and customers to solicit requirements, seek feedback, and provide updates.
• Collaborate closely with our customer success team, other engineers, and various stakeholders to explore opportunities, validate ideas, ship high-impact growth initiatives, and track/measure results.
• Drive experimentation — implement A/B tests, track key metrics, optimize conversion…
