Astra is building mission-critical infrastructure for moving money at scale. Our platform processes billions in annual transaction volume with 99.9%+ uptime, powering real-time transfers, bank debits, card disbursements, and complex financial compliance systems. We provide APIs and automation tools that enable businesses to move money programmatically while maintaining strict regulatory requirements.
We're looking for a Senior Fullstack Engineer who is primarily frontend-focused but comfortable contributing across the stack. You'll own the React and TypeScript surfaces our clients and internal teams depend on, while also being able to build and extend the Python APIs that support them. You'll work closely with our engineering team to ship features across our payments dashboard, internal tooling, and embedded product surfaces.
This role is a great fit if you think of yourself as a frontend engineer first, with enough backend range to move fast without always needing to hand off. Strong React and TypeScript skills are the foundation. Python fluency is a plus, not a prerequisite.
Lead frontend architecture decisions including component design, state management, performance, and scalability as our platform grows
Design and implement React and TypeScript interfaces for our payments dashboard, reporting surfaces, and embedded product experiences
Translate complex financial workflows into intuitive, accessible interfaces
Help establish and scale our frontend platform, including shared component libraries, tooling, and patterns the team builds on
Build and extend Python APIs that power frontend features
Collaborate with backend engineers on data contracts, API design, and integration patterns
Participate in system design discussions and bring a product-quality perspective to backend work
Establish and maintain frontend best practices, component libraries, and design patterns for a growing team
Mentor engineers and conduct code reviews with a focus on quality and consistency
Partner with product and design to refine requirements and push back when scope or UX is unclear
Build and improve internal tools used by our operations, compliance, and payments teams
Maintain high standards for reliability and usability across both external and internal surfaces
Requirements
5+ years of software engineering experience with significant frontend ownership
Strong production experience in React and TypeScript, these are the primary skills for this role
Enough backend range to build and extend APIs independently, Python experience preferred
Demonstrated ability to own features end to end, from data layer to UI
Experience working in a collaborative team with shared codebases and code review culture
Ability and willingness to travel up to ~15% annually
Education
Bachelor's degree in Computer Science, Engineering, or related field preferred, or equivalent practical experience
