About the role
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
