Senior backend blockchain engineer (Guadalajara)

Location: Guadalajara, Mexico (currently hybrid with up to 50% remote).

Responsibilities

• Work as a senior member of the backend team, partnering with developers, tech leads, frontend, QA, and producers on cross‑functional squads to analyze, design, build, and evolve the microservices (APIs, ETLs, edge services) that power our jukebox, mobile app, web, and TV experiences.
• Lead the design and delivery of RESTful API services from problem statement through production, including writing design documents and weighing architectural trade‑offs.
• Review code and designs from peers across the squad and the wider backend department, raising the bar on quality, testability, and operational readiness.
• Mentor mid‑level and junior engineers through pairing, design reviews, and structured knowledge sharing such as brown bags or internal documentation.
• Partner with product, frontend, QA, and SRE to shape roadmap items, surface dependencies early, and unblock the squad.
• Address scalability, redundancy, and operational resilience for services that handle several million requests per day.

Qualifications

• 5+ years of hands‑on experience in software development and/or Dev Ops, with a track record of shipping reliable, scalable backend systems in production.
• Strong software engineering fundamentals and excellent command of Java with Spring and Project Reactor (reactive programming), plus scripting in Python or Bash.
• Advanced understanding of modern backend architecture: clustering, proxies, caching layers, search infrastructure, message queues, and how these components interact under real production load.
• Hands‑on experience designing and optimizing data‑driven systems with both relational and NoSQL databases, including a working sense of when to reach for each.
• Practical AWS experience and a clear mental model of how cloud services compose into resilient systems.
• Comfortable owning Linux‑based, containerized services with Docker in production, including debugging issues that cross service boundaries.
• Strong grasp of testing and delivery practices: unit and integration testing, CI/CD pipelines (e.g., Jenkins), Git‑based branching workflows, and code review.
• Working knowledge of how backend systems serve customer‑facing products is a plus.
