Tech Lead – Ruby on Rails, Node.js

This is a fully remote position, open to applicants in Argentina.

📋 Description

• Define and communicate the technical direction of your team: service architecture, API contracts, event-driven flow design over Kafka, and strategies for evolving legacy systems.

• Design, build, and scale services using Rails and Node.js, focusing on reliability, performance, and maintainability.

• Be part of the technical architecture team, participating in decisions that span teams and services: domain boundaries, integration standards, observability, and resilience.

• Write and review RFCs and design proposals; clearly communicate complex technical trade-offs to both technical and non-technical audiences.

• Solve the most complex and far-reaching technical problems, including debugging distributed systems in production and incident response.

• Lead demanding yet constructive code and design reviews, raising the technical standard of the team.

• Mentor engineers at all levels, helping them grow technically and gain autonomy. Your success includes training the next generation of technical leaders.

• Collaborate with product and the Engineering Manager to translate business objectives into executable technical plans, knowing when to say no to the right things.

• Ensure quality standards: testing, CI/CD, security, and AI-assisted development practices with quality control.

⛳️ Requirements

• Proficient in English at B2 level or higher.

• Over 8 years of experience in software engineering, with deep expertise in production using both Ruby on Rails and Node.js (experience in only one is insufficient).

• Experience designing and operating microservices and APIs in production at scale, including event-driven systems (Kafka or equivalent).

• Practical experience with distributed systems: consistency, idempotency, handling partial failures, capacity planning, and observability (tracing, metrics, structured logging).

• Experience operating services in Kubernetes on a cloud provider (GCP, AWS, or Azure).

• Solid knowledge of modern frontend (React/Next.js) sufficient to make architectural decisions that span both frontend and backend.

• Demonstrated ability to mentor engineers and elevate the technical level of a team.

• Daily use of AI development tools, with discernment in reviewing and validating produced outcomes.
