Descrição

• As a Senior Backend Stack Engineer in the Core Platform Team, you’ll be a principal owner of the TMS (Translation Management System) Platform and connected services. • Driving the architecture, reliability, and evolution of services covering translation workflow orchestration, vendor management, customer management, and integrations with our internal services. • Setting the technical direction for these services: defining how they scale, and maintain the quality bar expected of infrastructure-grade software. • Own and evolve foundational services: Take end-to-end ownership of platform service driving their architecture, reliability, and roadmap. • Lead backend architecture decisions: Author architecture decision records, define service boundaries, and ensure services are designed for scalability, resilience, and long-term maintainability. • Design and enforce API contracts: Define and maintain clean, versioned, well-documented REST APIs consumed by internal teams and, increasingly, by AI agents. • Drive technical quality: Own non-functional requirements — performance, observability, security, and availability — across the services you lead. • Collaborate cross-functionally: Work with product managers and domain experts across the business to shape the platform roadmap and translate real needs into sound technical solutions.

🎯 Requisitos

• 5+ years of backend engineering experience in production environments, with deep expertise in C#, .NET Core / .NET 8+, ASP.NET Web API, and microservices architecture. • Proven track record of owning and evolving production services: schema migrations, API versioning, backward compatibility, and long-lived service maintenance. • Strong experience with distributed systems concepts: event-driven architecture, message queues (Azure Service Bus, RabbitMQ), sagas, idempotency, and eventual consistency. • Strong experience with AI developer tools (Using and building custom agents, skills, instructions) • Deep proficiency with relational databases (MSSQL and/or PostgreSQL): complex query design, schema design, indexing strategies, and performance tuning. • Demonstrated experience making and documenting architectural decisions (ADRs, system design, trade-off analysis) with the ability to defend and adapt your choices. • Hands-on DevOps experience: CI/CD pipelines, Docker, Kubernetes, Azure — with the mindset that owning deployment and operations is part of the engineer’s job. • Experience designing robust, versioned REST APIs consumed by multiple teams, including security considerations (OAuth 2.0, API key management, rate limiting). • Some frontend exposure (Vue.js and/or TypeScript) — enough to contribute when needed, but the primary focus here is backend and platform. • A track record of mentoring and uplifting junior engineers — through code reviews, design sessions, and raising the quality bar organically. • Strong communication skills and the ability to articulate technical decisions to both engineers and non-technical stakeholders. English fluency required. • Agile, collaborative, and opinionated in a constructive way — you push back when needed and bring others along.
