Senior Full-Stack Developer

We’re looking for a highly experienced Senior Full-Stack Developer (60 % Frontend / 40 % Backend) who can own complex, data-driven features end-to-end. This role is ideal for a senior, independent engineer who learns quickly, thrives in a fast-paced startup environment, and takes full responsibility for delivering high-impact work.

You’ll join a small, high-impact engineering team building a modern FinOps platform used by enterprise customers worldwide. The ideal candidate enjoys creating sophisticated user interfaces, has a deep understanding of modern frontend architecture, and brings strong backend depth — feeling confident designing and implementing complex server-side logic, APIs, and data flows as part of full feature ownership.

The role requires extensive experience building data-heavy systems with large datasets, aggregations, and performance-sensitive flows.

Responsibilities

• Designing and developing advanced UI features and dashboards (React + JavaScript / TypeScript)
• Designing and implementing data-heavy features involving large datasets, aggregations, performance optimization, and complex analytical flows
• Owning features end-to-end: design, architecture, implementation, testing, deployment
• Working across the stack: primarily frontend, with meaningful backend and server-side work
  Building and maintaining server-side logic, APIs, and integrations as part of the feature lifecycle
• Collaborating closely with product, backend, and data teams on requirements and solutions
  Troubleshooting bugs and performance issues (roughly 50% of the workload over time)
• Working in cloud-native environments (AWS)
• Using AI-assisted development tools to improve productivity and quality
• Contributing to code quality, performance, scalability, and maintainability

Requirements

• 6+ years of hands-on development experience as a Full-Stack Developer, strong on both frontend (React, JavaScript/TypeScript) and backend (Python, APIs, scalable services)
• Bachelor’s in Computer Science or related field
• Strong React and JavaScript/TypeScript skills for frontend, with experience delivering complex, data-heavy UI features
• 2+ years building Python backend APIs and scalable services, handling large datasets and performance-critical flows
• Experience with databases (SQL/NoSQL, DynamoDB, BigQuery) and AWS/cloud-native environments
• Familiarity with visualizations, graphs, and interactive dashboards; experience in B2B SaaS or data-centric products
• Meaningful experience working with data-heavy systems (large datasets, aggregations, performance considerations, etc.
• Independent, detail-oriented, fast learner with a strong ownership mindset; comfortable using AI-assisted development tools

Who you are

• A senior engineer who can pick up complex tasks quickly
• Someone who learns independently and doesn’t need constant guidance
• A proactive problem-solver with strong attention to detail
• A clear communicator who works well in a remote setup
• Someone who cares about user experience, performance, and clean code
• Comfortable balancing new feature development with ongoing bug fixes

What we offer

• Competitive salary and benefits package
