About Outpost

What if going global was as simple as going local

Outpost is building the AI global trade engine. The accumulated knowledge of every rule youd need to sell internationally turned into infrastructure. Tell us what youre selling. Well tell you how to sell it everywhere.

We operate as Merchant of Record or Tax of Record across 58 tax jurisdictions. Full liability transfer or just the tax layer. We do the analysis we handle the setup we absorb the liability.

Sell anything anywhere. Without compromise.

The Role

This is a Frontend Engineer role for someone who wants to build intuitive interfaces for complex financial operations.

Youll work directly with our engineering leadership to create the user experiences that power international commerce. Merchant dashboards payment flows tax compliance tools transaction monitoring and AI-powered analysis interfaces. Youll make complexity feel simple.

We believe great design is as much about what you leave out as what you put in. A well-designed interface should feel inevitable where every element has earned its place and complexity is made manageable through thoughtful design.

This isnt just about building beautiful interfaces. Youll tackle challenges like displaying real-time payment flows building tax compliance tools and developing merchant analytics. Youll also explore how emerging technologies can enhance our platform from AI-powered insights to advanced reporting.

What Youll Get

Yes the work is intense. But in return youll build the interfaces for critical financial infrastructure handling hundreds of millions in volume.

Youll have significant input into product and technical direction work with a small team of experienced engineers and shape how merchants experience global commerce. If you want to go deep on fintech product design and frontend architecture this is the role.

What Youll Build

  • Modern responsive merchant dashboard

  • Complex financial workflows and payment interfaces

  • Tax compliance and reporting tools

  • Transaction monitoring and risk management interfaces

  • AI-powered transaction analysis and compliance tools

  • Integrations with major e-commerce platforms

  • A best in class developer experience

  • Build scalable maintainable React applications

  • Establish frontend best practices and coding standards

  • Drive technical decisions for user interface components

  • Design and implement payment flow visualizations that surface issues instantly

  • Build AI-powered tools for transaction analysis and anomaly detection

  • Create the integration setup experience for Shopify and other e-commerce platforms

  • Develop the self-service onboarding flow that gets merchants live faster

What Were Looking For

Ideal background:

  • TypeScript with strong typing practices and type modeling

  • Youre comfortable with ambiguity and figuring things out

  • You contribute to product discussions not just implement specs

  • You want to build from scratch not maintain existing systems

  • Bias for action. You ship you learn you iterate

What this role is not:

  • Not maintaining existing systems. Youll build from scratch

  • Not a role where you wait to be told what to do

  • Not someone who needs heavy process or detailed specs to be effective

  • Not pure execution without input into product direction

Why This Role Is Different

Most frontend roles are about building features on top of existing products. This role is about creating the entire user experience for complex financial infrastructure.

Youll design how merchants interact with payments tax compliance and global commerce. Youll explore how AI can enhance these interfaces. Youll have real input into what we build and how it works.

If youre excited about building complex financial interfaces and exploring innovative solutions in international commerce this is the role.
