Senior Backend Engineer

Responsibilities

• 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.
• Drive the architecture, reliability, and evolution of services covering translation workflow orchestration, vendor management, customer management, and integrations with our internal services.
• Set the technical direction for services: defining how they scale, exposing capabilities to other teams, and maintaining the quality bar expected of infrastructure‑grade software.
• Take end‑to‑end ownership of platform service driving their architecture, reliability, and roadmap.
• Author architecture decision records, define service boundaries, and ensure services are designed for scalability, resilience, and long‑term maintainability.
• Define and maintain clean, versioned, well‑documented REST APIs consumed by internal teams and AI agents.
• Own non‑functional requirements like performance, observability, security, and availability across the services you lead.
• From architecture and coding to deployment, monitoring, and on‑call support ("You build it, you run it").
• Mentor and upskill the team:
  Support mid‑level and junior engineers through code reviews, pairing, and hands‑on architectural guidance.
• Work with product managers and domain experts across the business to shape the platform roadmap and translate real needs into sound technical solutions.

• 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 Dev Ops 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 Type Script) — 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.
