Lead Business Analyst (Enterprise Modernisation, Platform and Cloud)

Thoughtworks

Are you a seasoned technologist who thrives at the intersection of business strategy, architecture, and modern engineering practices?  Thoughtworks Singapore is looking for a seasoned technologist to partner with and guide our client organisations through complex platform and portfolio modernisation, translating technical strategy into measurable business value. In this high-impact role, you will be accountable for designing, selling, and leading the implementation of large-scale transformation and modernisation strategies, from initial vision through to successful execution. While this is not a primary hands-on coding role, you must possess the depth of technical credibility required to engage deeply with client C-suite and technical leadership, challenge assumptions, ask the right questions, and shape an ambitious modernisation strategy grounded in engineering excellence. You don’t need to tick every box. If you’re a strong seasoned technologist with a passion for driving change, we’d love to hear from you. JOB RESPONSIBILITIES * You will define the optimal target architecture for large-scale software application modernisation, explicitly leading the analysis of complex trade-offs to align the design with non-functional requirements and business objectives. * You will partner with business and technology leaders to identify modernisation opportunities, shape transformation approaches, and align technology decisions with business goals. * You will be involved with pre-sales, lead generation, creating proposals, shaping engagements for clients and helping to educate both clients and colleagues about the value of our services and the commercial success they can deliver. * You will act as a trusted advisor to C-level executives, helping them navigate complex legacy landscapes, make informed technical trade-offs, and redefine what’s possible in their industry. * You will contribute thought leadership through points of view, reusable patterns, accelerators, and modernisation practices that scale across regions. * You will support delivery teams by providing architectural direction, context, and decision frameworks that help them execute modernisation programs effectively. * You will mentor and develop consultants and technologists, nurturing the next generation of modernisation leaders at Thoughtworks. * You will stay current with emerging technologies and Thoughtworks’ global strategy, contributing insights that help us evolve our approach to modernisation. JOB QUALIFICATIONS TECHNICAL SKILLS * * A strong architectural foundation with the ability to reason about legacy systems, distributed architectures, and modern engineering practices. * Experience driving large-scale application modernisation or migration programs in complex organisations (e.g., banking, insurance, telco, government, energy, logistics, or similarly scaled domains). * You have experience designing and leading modern, distributed architectures (e.g., containers, service mesh, event streaming). * Understanding of modern architectural approaches such as microservices, event-driven systems, API-first design, and cloud-native patterns. * Familiarity with distributed systems concepts such as consistency models, data streaming, synchronous vs asynchronous communication, and resilience patterns. * Knowledge of reliability, availability, and disaster recovery approaches across multi-AZ, multi-region, and multi-cloud environments. * Appreciation for security-by-design and performance considerations from the outset of solution design. * Ability to communicate technical positions effectively to skilled architects and senior engineering leaders. * Experience guiding teams through Agile, Lean, Continuous Delivery, DevOps, or SRE-aligned delivery models. Specific technologies we often encounter include Kubernetes, Kafka, Istio, event streaming platforms, and modern cloud services. Experience with these is helpful but not required — what matters is your ability to evaluate, reason, and guide decisions around modern distributed systems. PROFESSIONAL SKILLS * Demonstrated experience working with senior business and technology stakeholders, including C-level executives * Ability to translate complex technical concepts into business value and commercial outcomes * Strong consultative, advisory, and influencing skills * Comfort navigating ambiguity, shaping vision, and bringing structure to large-scale transformation * A collaborative, inclusive, leadership style aligned with Thoughtworks’ values OTHER THINGS TO KNOW LEARNING & DEVELOPMENT There is no one-size-fits-all career path at Thoughtworks: however you want to develop your career is entirely up to you.
