About the Role

We’re looking for a Senior Full Stack Developer to join a remote-first team building an advanced analytics and payments platform.

This role requires an engineer who is comfortable working across the entire stack—from frontend interfaces to backend services and production infrastructure—and who understands that being “full stack” means owning systems end-to-end, not just implementing features.

You will work in a production environment where correctness, reliability, and operational awareness matter. While parts of the system currently utilize technologies such as Node.js, TypeScript, React, Docker, and cloud platforms, we value engineers who have broader exposure to multiple technologies and paradigms, and who can quickly learn unfamiliar stacks.

Key Responsibilities

• Own and develop full-stack functionality from problem definition through production deployment and iteration

• Design, implement, and maintain backend services and APIs supporting analytics and payment workflows

• Build and evolve frontend applications with a focus on performance, correctness, and maintainability

• Take responsibility for production systems, including diagnosing and fixing production bugs, handling incidents or outages, and understanding system behavior under load and failure

• Make pragmatic architectural choices and implement decisions under real-world constraints

• Integrate and maintain third-party services such as payment providers

• Work with cloud infrastructure and deployments without requiring extensive handholding

• Review code and designs with an emphasis on clarity, simplicity, and long-term ownership

• Collaborate closely with product and engineering peers to deliver measurable business value

Qualifications and Required Skill Set & Experience

• Bachelor’s degree in Computer Science, Computer Engineering, or another STEM field (or equivalent practical experience)

• 4+ years of professional experience in full-stack or generalist software engineering roles

• 4+ years of experience working on production systems used by real users

• Experience contributing meaningfully to complex, production-grade systems

• Experience working across backend, frontend, and infrastructure/production environments

• Strong programming fundamentals and ability to reason about systems beyond a single language or framework

• Proven ability to debug complex issues in unfamiliar codebases

• Solid understanding of system design, data modeling, and API design

• Experience applying advanced algorithms and data structures in real-world applications

• Professional experience with at least two compiled or functional languages, such as C/C++, Java, Kotlin, Clojure, Go, C#/.NET, Erlang/Elixir/Gleam, Nim, Rust, Zig, Haskell, or OCaml

• Experience with scripting languages used for automation, tooling, or operational tasks, such as Bash / Shell scripting, Python, Go, Perl

• Hands-on experience with cloud environments and compute platforms, such as AWS EC2, Google Compute Engine, AWS Fargate, Google Cloud Run, Kubernetes (K8s), and /or Virtual Private Clouds (VPCs)

• Exposure to infrastructure automation and operational tooling, including Terraform, Pulumi, Ansible, and Jenkins

• First-hand experience dealing with production bugs, degraded performance, outages or incidents, and distributed systems behaving unexpectedly

• Ability to clearly explain what you built, what made it complex, what went wrong, and how you improved it

• Clear understanding of engineering ownership versus feature delivery

• Strong communication skills and English fluency (written and verbal)

Nice to Have

• Experience in fintech, payments, or financial systems

• Contributions to open-source projects or substantial personal projects

• Experience improving engineering or business metrics in measurable ways

• Exposure to monitoring, observability, or incident response practices

Additional Requirements

• Comfortable working remotely with minimal supervision

• Proactive, detail-oriented, and collaborative

• Ability to thrive in a fast-paced, startup-like environment.
