Job summary

Cyclops is seeking a Senior Software Engineer with a strong backend focus to own features end-to-end in a product-driven environment. The role mixes backend work (70%) with some UI/SDK integration tasks (30%), emphasizing production reliability and clear API boundaries.

You will shape technical solutions, work closely with Product, Engineering Manager, and senior engineers, and mentor mid-level engineers while occasionally contributing to React UI tasks.

Qualifications

• 4+ years of professional software development experience.
• Strong backend expertise with TypeScript and Node.js.
• Experience owning a service end-to-end, from requirements to production support.
• Clear product-level architectural thinking: well-designed APIs, correct data boundaries, proper error handling.
• Understanding of microservice architectures and platform-level interactions.
• Strong knowledge of HTTP APIs, SQL data modeling, and common failure modes.
• Proficient daily use of AI coding tools (e.g. Claude Code), with the ability to review AI-generated code quickly and critically.
• Readiness to build deep working knowledge of crypto and stablecoin payments: prior crypto experience is optional, and deep on-the-job learning of the domain is a mandatory part of the role.
• Ability to work with ambiguity: ask the right questions and structure unclear problems, working independently without overly detailed technical specs.
• High agency: you notice problems before they are assigned to you, raise risks early, and bring a proposed solution together with the problem.
• Strong written and verbal communication in English.

Responsibilities

• Design and implement backend-heavy features using TypeScript and Node.js; build and evolve REST APIs with focus on correctness, consistency, and clear boundaries between services.
• Work with SQL (PostgreSQL): data modeling, migrations, and consistency guarantees.
• Take full ownership of one or more services, from requirements and implementation to production support, and drive integration work with external partners (vendors, clients) when needed.
• Own production behavior: investigate incidents, debug API failures, analyze data issues, and apply reliability patterns (timeouts, retries, idempotency, graceful degradation).
• Improve observability (logs, metrics, visibility into system behavior) and propose improvements where reliability, performance, or monitoring is weak.
• Participate in tech spikes: explore unclear problems and turn them into concrete technical plans.
• Collaborate with Product and EM to clarify requirements and reduce ambiguity early; contribute to technical discussions, raise risks, and explain trade-offs.
• Review code, mentor mid-level engineers, and contribute to React code when features require UI updates or customer-facing flows.
