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. DESCRIPTION Own the end-to-end technical architecture of the product across UI, API, microservices, data, messaging, caching and cloud infrastructure. Define and continuously evolve the reference architecture, target-state blueprints and technology roadmap; balance build-vs-buy and monolith-vs-microservice trade-offs. Translate complex business requirements into clear, well-scoped technical solutions and decision records. Establish architecture principles, design patterns, coding standards and review gates; chair the architecture review board and approve high-impact designs. Drive modernisation initiatives - framework upgrades, containerisation, observability, zero-trust networking and platform consolidation. Design for scale, resilience, multi-tenancy and data residency; define SLOs/SLAs together with SRE and product. Remain a strong individual contributor: prototype critical components, write reference implementations and own production code for the toughest 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. Design event flows on the messaging backbone - topics, queues, dead-letter handling, idempotency and replay. Define UI architecture patterns for the SPA - module structure, lazy loading, state management, design-system adoption and accessibility. Own the cloud landing zone - networking, identity, secrets management, storage, managed databases, monitoring and cost governance. Define security architecture aligned with ISO 27001, SOC 2, GDPR and other applicable regimes; embed security-by-design across every layer. Drive secrets hygiene, encryption-at-rest and in-transit, key rotation and least-privilege access across the estate. Partner with Information Security on threat modelling, vulnerability management, penetration test remediation and audit response. Architect integrations with third-party systems, payment gateways and identity providers via APIs, webhooks, file-based batch and event streams. Define and uphold CI/CD pipelines, branching strategy and release management across the .NET, front-end and Linux microservice estates. Establish observability standards - structured logging, metrics, distributed tracing and alerting - across the stack. Drive automated testing strategy (unit, integration, contract, performance, security) and define quality gates and code-coverage targets with QA leads. Lead production incident response for architecture-level issues; conduct blameless post-mortems and convert findings into durable design changes. Provide architectural guidance to multiple squads of full-stack engineers, team leads and senior engineers; act as the ultimate technical escalation point. Mentor and grow architects, leads and senior engineers; raise the technical bar through reviews, design clinics and brown-bag sessions. Partner with Product Management on roadmap shaping, effort sizing, sequencing and feasibility of new capabilities.
