Description
LanguageWire is a global leader in language and content services, dedicated to helping brands achieve their full global potential. Since 2000, we’ve evolved and built unique technology that enables seamless multilingual communication. Our worldwide network of language experts, together with our intuitive online platform, empowers brands to translate and manage multilingual content effortlessly. The role you’ll play  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. That means driving the architecture, reliability, and evolution of services covering translation workflow orchestration, vendor management, customer management, and integrations with our internal services – file transformation, machine translation and many more.  You will set the technical direction for these services: defining how they scale, how they expose capabilities to other teams, and how they maintain the quality bar expected of infrastructure-grade software.  This is a role for someone who takes genuine pride in the craft of building robust, well-designed systems and who wants to be a multiplier: raising the technical level of the team around them, not just shipping code. The team you’ll be a part of  You’ll join the Core Platform Team, one of the foundational engineering teams at LanguageWire. The team owns and operates multiple services that build up to the TMS Platform. These are the services our whole operation depends on.  We value outcomes over output, shared ownership over silos, and continuous delivery over long release cycles. Our stack is built on .NET services, Azure, and modern API patterns.  If you want to make a difference, make it with us by…  TMS Platform ownership  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.  Own your services end-to-end: From architecture and coding to deployment, monitoring, and on-call support (“You build it, you run it”).  Technical leadership & team growth  Mentor and upskill the team: Support mid-level and junior engineers through code reviews, pairing, and hands-on architectural guidance.  Set and raise the engineering bar: Champion best practices in testing, code quality, incident response, and continuous delivery across the team.  Drive DevOps and operational excellence: Own CI/CD pipelines, deployment reliability, and ensure platform services are observable, resilient, and secure.  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. In one year, you’ll know you were successful if…  The core platform services you own are more reliable, better documented, and better understood across the organization than when you joined.  You have led at least one significant architectural improvement that measurably improved scalability, resilience, or developer experience for dependent tea
