About Astra
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.
The Role
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.
What You’ll Do: Own the Frontend Architecture
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
Contribute Across the Stack
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
Drive Frontend Standards
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
Support Internal Tooling
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
What We’re Looking For: Senior Fullstack Engineer 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
Education
Bachelor's degree in Computer Science, Engineering, or related field preferred, or equivalent practical experience
Technical Skills
Frontend: React, TypeScript, component architecture, state management
Backend: Python, REST APIs, web frameworks
Database: Experience with SQL and NoSQL databases
Cloud: Google Cloud Platform or similar
Tooling: Git, CI/CD, testing frameworks
Preferred Experience
Data visualization and reporting: experience building charts, dashboards, or analytics surfaces
Financial or fintech products, including dashboards, reporting, or transaction workflows
Design system or component library ownership
Experience with internal tooling for operations or compliance teams
Familiarity with domain-driven design or clean architecture patterns
Why This Role Matters
Direct Impact: You'll be a core part of a small, high-output engineering team with real ownership over the product experience
Frontend Ownership: Lead the frontend architecture and set the bar for quality across our interfaces
Complex Problems: Work on sophisticated payment workflows that few engineers get to build
Team Building: Establish frontend engineering practices and culture as we scale
Financial Innovation: Build the interfaces that make financial infrastructure accessible to our clients
What We Offer
Competitive compensation with equity in a growing fintech company.
Remote-first culture with flexible working arrangements
Small team, big impact — your work directly supports Astra’s ability to scale responsibly
Professional growth opportunities in compliance and risk management
Mission-driven — build infrastructure that powers financial innovation while meeting the highest regulatory standards
Remote Work and Culture
Astra is a remote-first company hiring only within the U.S. We value thoughtful collaboration, clarity, and initiative. We’re proud to be an equal opportunity employer and are committed to building a diverse and inclusive team.
How to Apply
We're looking for engineers who care about product quality as much as technical craft. If you're excited by the challenge of making complex financial systems feel simple to use, and you want real ownership on a small team, we'd love to hear from you.
