Lead Engineers at Thoughtworks act as trusted technical leaders and security advisors who align enterprise risk and executive strategy with modern software delivery, ensuring security measures enhance organizational objectives. In this role, you bring a strategic and proactive mindset to client engagements, guiding delivery teams in embedding security directly into the software development lifecycle, platform architecture, and cloud environments. You balance high-level security architecture with hands-on engineering, conducting threat modeling, establishing DevSecOps practices, and following a pragmatic and robust approach to risk management. As a technical leader, you guide and coach cross-functional teams, cultivate security awareness across accounts, and navigate complex stakeholder environments to build resilient, trustworthy software solutions. Due to the nature of the projects and specific client security clearance , this role requires the successful candidate to be a Singapore Citizen. Job Responsibilities You will lead the design and implementation of enterprise security architectures, zero-trust patterns, and DevSecOps practices and controls across software delivery teams. You will act as a primary technical advisor to client stakeholders and engineering leads, aligning information security strategies with enterprise risk tolerances and business goals. You will champion shifting security left in the software development lifecycle by integrating automated SAST, DAST, SCA, and secrets management into CI/CD pipelines. You will conduct threat modeling sessions, security risk assessments, and architectural reviews to identify vulnerabilities and design pragmatic mitigations alongside delivery teams. You will oversee cloud platform security governance, Identity and Access Management (IAM), container security (Kubernetes, Docker), and Infrastructure as Code (IaC) compliance across AWS, Azure, or GCP. You will guide vulnerability management, security incident response workflows, and audit readiness to ensure alignment with industry regulations and public sector standards (e.g., Singapore IM8 / IM8+, SOC 2, ISO 27001, NIST). You will partner closely with cross-functional teams—including software developers, infrastructure engineers, quality analysts, and product managers—to balance security controls with delivery velocity. You will cultivate Thoughtworker growth and development by mentoring engineers, providing ongoing supportive feedback, and fostering an inclusive team culture. You will apply the latest technology thinking and security insights from our Technology Radar to solve complex client security challenges. You will contribute to Thoughtworks’ security community of practice, supporting pre-sales pursuits, capability development, and technical thought leadership. Professional Skills You bring 7+ years of experience in information security engineering, application security, or cloud security within fast-paced software delivery environments. You possess deep expertise in secure software development practices, threat modeling methodologies (e.g., STRIDE, PASTA), and security standards such as OWASP Top 10 and SANS Top 25. You have hands-on experience with security automation tools (SAST, DAST, IAST, SCA, secrets scanners) and integrating them into continuous integration and continuous delivery pipelines. You bring strong technical capabilities in securing cloud infrastructure (AWS, Azure, GCP), container platforms (Kubernetes, Docker), and Infrastructure as Code (IaC) environments. You have a solid foundation in cryptography, Identity and Access Management (IAM), zero-trust architecture, network security, and API security. You possess practical knowledge of regulatory frameworks and compliance standards, such as Singapore Public Sector IM8 / IM8+, SOC 2, ISO 27001 (ISMS), PCI-DSS, or GDPR. You are a natural mentor and technical leader, skilled at inspiring cross-functional teams, driving security awareness, and coaching peers. You demonstrate excellent communication and stakeholder management skills, with a proven ability to translate complex security risks into actionable business decisions for leadership. You are resilient in ambiguous situations, capable of evaluating trade-offs under constraints and solving security challenges from technical and business perspectives. You bring an open and thoughtful mindset toward AI, exploring AI-assisted security automation, threat detection, and responsible AI governance practices.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
