Job description

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

Requirements

What We’re Looking For

• 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

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.

Compensation Range: $190K - $230K
