Descripción del trabajo

Pluxee is a global player in employee benefits and engagement that operates in 28 countries. Pluxee helps companies attract, engage, and retain talent thanks to a broad range of solutions across Meal & Food, Wellbeing, Lifestyle, Reward & Recognition, and Public Benefits. Powered by leading technology and more than 5,000 engaged team members, Pluxee acts as a trusted partner within a highly interconnected B2B2C ecosystem made up of more than 500,000 clients, 36 million consumers and 1.7 million merchants. Conducting its business as a trusted partner for more than 45 years, Pluxee is committed to creating a positive impact on all its stakeholders, from driving business to local communities, to supporting wellbeing at work for employees while protecting the planet.

Your next challenge Join Pluxee as a Senior Backend Engineer and become a key contributor of the product that employees actually experience every day. You'll join the Benefits Squad , the team at the center of Cobee by Pluxee: we own the domain that defines what benefits an employee can access, under what conditions, with what limits, and in what markets. This is where business complexity lives. Benefits isn't a simple CRUD layer - it's a rich domain with multi-tenant configurations, eligibility rules that vary by company, country, tax compliance requirements and real-time state that must always be consistent. Getting it right means hundreds of thousands of employees get their benefits seamlessly. Getting it wrong is visible immediately.

Key Responsibilities

• Own the Core Domain Model : Design and evolve the backend services that define how benefits work - plans, entitlements, limits, and eligibility - ensuring the model stays clean, consistent, and extensible as we grow into new markets and product lines.
• Tame Business Complexity : Translate intricate, multi-country regulatory and business rules into robust, maintainable code. You'll work closely with Product and Operations to model edge cases that matter in the real world.
• Build for Consistency at Scale : Design systems where data integrity is non-negotiable across multi-tenant configurations, concurrent transactions, and distributed state - even as traffic and product scope grow.
• Drive Product Velocity Without Cutting Corners : Deliver new benefit types, configurations, and market expansions at speed, without accumulating technical debt that slows down future iterations. You understand that clean domain design is the fastest path to sustainable velocity.
• Quality as a Product Requirement : Write tests that encode business rules, not just code paths. In a domain where a misconfigured eligibility rule affects thousands of employees, comprehensive test coverage is a feature, not a hygiene task.
• Operational Excellence & Observability : Monitor domain health in production. Build the dashboards and alerts that let the team detect when a benefit isn't being applied correctly before an employee notices.
• Technical Leadership : Raise the bar through deep code reviews, clear technical documentation, and mentoring. Help the squad develop shared vocabulary for the domain - the kind of codebase where new engineers become productive fast.
• AI-Driven Execution : Actively leverage AI tools and coding assistants on a daily basis to accelerate development cycles, automate repetitive tasks, and optimize overall team processes and delivery speed.

Our daily stack is: TypeScript, Node.js,React, React Native, Auth0, MongoDB (Atlas). We add tests to everything. Also, we log what's going on internally using Sentry. We have our CI/CD with GitlabCI and we deploy several times each day. Code collaboration: GitHub, Gitlab, Docker, K8 AI & Productivity: GitHub Copilot, Claude Sonnet, ChatGPT, and other GenAI assistants. Project management and knowledge: JIRA, Confluence Communication: Teams You are a match

Proven Senior Expertise: 5+ years of experience developing production-grade applications. Experience within the Node.js ecosystem will be a plus.

Distributed Systems Mastery: Deep understanding of race conditions, eventual consistency, idempotency, and message brokers is a must. Experience in developing medium/large-scale web applications and distributed systems. Experience operating your services in a production environment. Experience with unit, integration, functional, and e2e testing.

AI-Empowered Developer : A strong inclination to lean on AI tools for problem-solving, code generation, and workflow optimization, always looking for ways to work smarter and improve team efficiency.

Problem-Solving DNA: A systematic approach to troubleshooting complex issues in high-concurrency environments.

Quality First: Extensive experience with automated testing patterns and a "shift-left" security mindset.

Growth Mindset: A passion for continuous learning, open to feedback, and a drive to help others improve their craft.

Spanish & English fluency.
