Overview
As a Frontend Engineer at Bastion, you’ll play a critical role in crafting exceptional user experiences across our core products. You'll lead the development of elegant, responsive, and accessible interfaces, transforming complex requirements into simple and performant UIs. Your work will directly shape how users interact with Bastion’s compliance and fintech tools, impacting everything from initial onboarding to real-time workflows.
This is a 0 → 1 environment ideal for engineers who thrive on ownership, autonomy, and hands-on collaboration with designers, backend engineers, and product stakeholders. You'll influence architectural decisions, define frontend patterns, and contribute to our design system as we scale.
A strong sense of visual and interaction design, paired with an instinct for clean abstractions, will be key to success in this role. We value engineers who take pride in crafting polished UIs, have a track record of self-initiated projects or end-to-end ownership, and are motivated by building experiences users love. Experience in fintech is a strong plus, as is a forward-looking mindset that’s excited by the potential of web3 applications.

Comfortable with Git workflows, code reviews, and modern CI/CD practices
Experience collaborating closely with designers and translating high-fidelity designs into code
Self-starter with a track record of end-to-end project ownership or meaningful side projects
