-

- 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.

Requirements

-

- 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. xhfqzwm

- Agile, collaborative, and opinionated in a constructive way — you push back when needed and bring others along.
