About Us
Solvedex reshapes the future of tech talent through fractional technology leadership. We provide experienced, pre-vetted leaders who integrate seamlessly to guide strategy, execution, and growth, handling alignment and oversight so organizations can stay focused on innovation
About the Role
We’re looking for a Mid to 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 at least two 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.
