Senior Technical Architect

OVERVIEW TransPerfect helps organizations navigate the global marketplace. Founder-led for more than three decades, the company has grown organically into the world's largest translation and language services provider, with thousands of employees across 100+ offices and over $1B in annual revenue. The TransPerfect TechOps team has been a vital part of the company's success since its formation over a decade ago - delivering technology and services that have drastically simplified the lives of our clients and colleagues, from workflow improvements for colleagues to core platform services and scalable client-facing applications. About this role: We are looking for a hands-on Senior Technical Architect to own the end-to-end architecture of one of our flagship enterprise SaaS products. You will set the technical vision, evolve the multi-tier reference architecture, drive modernisation initiatives, and partner with product, security and SRE leaders to scale the platform across new tenants, geographies and compliance regimes - while remaining a strong individual contributor on the hardest engineering problems.

Design and review APIs (RESTful, event-driven and async); define service contracts and integration patterns. Architect data models, schema-evolution strategies, indexing, partitioning and archival on the primary RDBMS; tune slow paths and define caching strategies.

Define security architecture aligned with ISO 27001, SOC 2, GDPR and other applicable regimes; embed security-by-design across every layer.
