About the Role
We’re looking for a Senior Software Engineer to join our growing team and play a key role in building reliable, performant, and scalable systems across our product. You’ll work across the stack—from TypeScript APIs to modern React frontends—helping define architecture, improve developer experience, and drive code quality across the team.
In this role, you’ll be expected to work closely with product, design, and fellow engineers to deliver user-facing features, refine our internal APIs, and evolve our platform architecture as we scale. You will see projects through from conception to production and everything in between.

What you’ll do
As a Senior Software Engineer at Jona, you will:

• Drive Technical Decisions:
  • Propose, architect, and implement projects from the ground up.
  • Design, implement, and maintain scalable systems and APIs.
  • Drive modernization of legacy systems and ensure adherence to best practices.
• Collaborate & Communicate
  • Work directly with other engineers, designers, and product management to efficiently deliver high-quality features for both external and internal audiences.
  • Build, test, and deploy new features across frontend and backend systems.
  • Ensure performant, accessible, and maintainable code on both client and server sides.
• Take Ownership & Propose Improvements
  • Don’t simply write code, own it all the way to production.
  • Continually improve our software delivery process.
  • Stay current with emerging technologies and frameworks, evaluating their fit for the organization.
  • Propose and lead initiatives that improve developer experience, CI/CD pipelines, and internal tooling.
  • Identify and resolve performance bottlenecks across frontend and backend services.

About you

• You are self-motivated and can work independently in a remote-first environment with minimal guidance.
• You take pride in your ability to deliver efficient and maintainable software.
• You stay current in the industry and are always on the lookout for opportunities to leverage.
• You have experience across the entire stack and think of yourself as true generalist.
• You are a supportive team player who doesn’t hesitate to offer a helping hand.
• You are excited by the idea of optimizing complex solutions to general problems.

What You’ll Bring

• 5+ years of professional experience building modern TypeScript web applications
• Deep understanding of React and Node.js
• Experience designing and integrating with RESTful and RPC-style APIs
• Strong knowledge of SQL (PostgreSQL preferred) and data modeling best practices
• Understand relational and non-relational databases
• Familiarity with modern CI/CD pipelines (GitHub Actions preferred)
• Experience building and deploying production workloads on AWS
• Experience improving codebases through testing, observability, and refactoring
• Strong communication and collaboration skills, with a product-minded approach
• An understanding of security issues and responsibilities

Nice-to-haves
