Role Summary We are hiring a Senior Software Engineer to help build the future of technical interviewing and assessment across CoderPad. This is a fullstack role for someone who can move across backend services, frontend product surfaces, and AI-powered system design. You will work on user-facing features, production infrastructure, and internal engineering workflows where coding agents and AI-assisted development are part of normal day-to-day execution. This role is remote from Latin America.

What You Will Work On

Build and ship fullstack product features across candidate and recruiter experiences, from API and data model design to frontend implementation. Improve real-time AI-powered experiences used in interviews and assessments, including model orchestration, streaming UX, tool/function-calling patterns, and reliability. Partner across product, design, and platform teams to take ambiguous problems from definition to production rollout.

Lead and mentor through code review, using reviews as both a quality gate and a coaching channel for less-experienced engineers. Plan and deliver technical debt, architecture, and observability initiatives that improve long-term system maintainability.

Requirements Senior-level experience shipping production software end-to-end in a fullstack capacity. Strong backend engineering skills in at least one modern language and ecosystem, plus practical frontend experience with a component-based framework. Significant contribution to code review,



with evidence of raising code quality and mentoring peers through the review process.

Experience identifying and reducing technical debt, and contributing to architecture planning and documentation. Proven ownership of production system health through monitoring/alerting improvements, incident response, and operational follow-through.

Experience partnering with product and technical leads on backlog preparation, scoping, sizing, and delivery planning. Strong engineering fundamentals in testing, observability, debugging, and safe incremental delivery. Clear written communication and collaborative ownership mindset in remote teams.

Backend surfaces include Ruby on Rails, Java services, and Node/TypeScript services. Frontend surfaces include React + TypeScript applications and shared web platform tooling. Platform and infrastructure include PostgreSQL, GraphQL, Redis/Sidekiq, Firebase Realtime Database, Datadog, LaunchDarkly, GitLab CI, cloud services (AWS and GCP), and containerized execution environments.

Internal engineering workflows include Python-based deterministic CLI tooling and AI-agent skills that support repeatable development operations.

How We Work

Remote-first collaboration across time zones with a strong written culture. Small, reviewable changes with high-quality code review and shared ownership of outcomes. Senior ICs influence technical roadmap direction beyond their immediate delivery scope. If you would like more information about how your data is processed, please contact us.
