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. REQUIRED SKILLS & EXPERIENCE • 20+ years of professional software engineering experience, with at least 5 years in a formal Architect role on a production SaaS product. • Bachelor's or Master's degree in Computer Science, Information Technology, Mathematics or a related field; MCA/BCA also considered. • Demonstrated track record of architecting and scaling a multi-tier, multi-tenant SaaS platform. • Deep, production-level expertise in .NET / .NET Core, C#, ASP.NET and Web API hosted on IIS and Windows Server. • Strong command of microservices architecture, RESTful API design, API versioning, contract-first design and API gateway patterns. • Solid hands-on experience with event-driven and asynchronous architectures using RabbitMQ (exchanges, queues, routing, DLQs, idempotency, ordering). • Hands-on experience designing and operating distributed caches with Redis. • Proficiency with modern Angular (Angular 12+), TypeScript, RxJS, HTML5 and CSS3, and component-driven SPA architecture. • Strong PostgreSQL skills - schema design, indexing, query optimisation, partitioning, replication and backup/restore on a managed-database service. • Hands-on Microsoft Azure experience - networking (VNet, NSG, Private Link, VPN), Azure Blob Storage, Azure Key Vault, Managed PostgreSQL, monitoring and cost management. • Strong working knowledge of Windows Server and IIS as well as Ubuntu and NGINX for the Linux services tier. • Solid grasp of TLS, certificate management, identity (OIDC / OAuth2 / SAML), RBAC and secrets management. • Proficiency with Git and branching strategies, and CI/CD using Azure DevOps, GitLab CI or equivalent. • Familiarity with Infrastructure as Code (Terraform, Bicep or ARM) and configuration management. • Deep knowledge of SDLC, Agile and Scrum, with experience using Jira, Azure Boards, Confluence and similar tools. • Experience defining observability standards using APM / tracing / logging tools (e.g., Application Insights, Datadog, New Relic, ELK). • A strong systems-thinker with the ability to zoom from a single SQL query to multi-tier architecture without losing context. • Demonstrated track record of mentoring engineers, growing technical talent and building a culture of ownership and learning.
