Job description

Who We Are

Boston Consulting Group partners with leaders in business and society to tackle their most important challenges and capture their greatest opportunities. BCG was the pioneer in business strategy when it was founded in 1963. Today, we help clients with total transformation-inspiring complex change, enabling organizations to grow, building competitive advantage, and driving bottom-line impact.

What You'll Do

You will join our squad responsible for Enterprise Services on the ServiceNow platform, with a strong focus on Customer Service Management (CSM) and scoped applications. The squad delivers and operates business-critical solutions used globally across BCG.

In this role, you will act as the Technical Owner for the squad's products, owning the technical "how" and partnering closely with the Product Owner to translate business needs into robust, scalable solutions. You will be the primary technical decision-maker for design choices, implementation quality, and long-term sustainability, including the integrations, performance, and overall health of the products in your scope.

This is a hands-on role. You will design, build, configure, and evolve ServiceNow capabilities, including workflows, integrations, automations, and reporting, using core platform features such as Flow Designer, IntegrationHub, UI Builder, and Performance Analytics. You will work closely with engineers, architects, and stakeholders to keep solutions aligned with enterprise architecture principles and platform governance, proactively managing technical debt, promoting reuse of patterns, and keeping application boundaries clean so the platform stays extensible.

You will operate with a high degree of autonomy, raise the technical bar across the squad through design discussions, code reviews, and mentoring, and surface risks, trade-offs, and modernization needs early.

YOU'RE GOOD AT

• Owning the technical narrative for the squad's products, clearly articulating designs, decisions, risks, and trade-offs, and holding firm in technical discussions with senior stakeholders
• Designing robust, scalable, and secure ServiceNow solutions aligned with platform governance and enterprise architecture standards
• Delivering high-quality results with minimal supervision, and identifying opportunities for improvement that enhance platform capabilities
• Creating clear and concise design and technical documentation to support robust implementation and long-term maintainability
• Communicating effectively with technical and non-technical stakeholders, including well-structured demos and insightful data analysis
• Troubleshooting complex technical issues efficiently, with a focus on root cause analysis and sustainable fixes
• Coaching and developing other engineers through code reviews, design discussions, and hands-on pairing
• Working with high autonomy while collaborating effectively across squads, chapters, and architecture roles in a fast-paced Agile environment

What You'll Bring

• 8+ years of experience developing and maintaining ServiceNow solutions in complex, enterprise environments
• Demonstrated experience as the senior technical reference for a product or squad, owning design decisions end to end
• Strong hands-on experience with ServiceNow CSM
• Proven experience designing and delivering scoped applications, including application boundaries, cross-scope access, and lifecycle management through source control
• Experience in solution performance, integrations, and overall product reliability (experience with upgrades and maintenance is a plus)
• Proficiency in JavaScript and ServiceNow development, including server and client-side scripting, security, performance considerations, and debugging
• Experience designing and building ServiceNow integrations using REST, GraphQL, IntegrationHub, security configuration, and third-party apps
• Experience mentoring engineers and establishing engineering standards within a team
• ServiceNow certifications are highly preferred (e.g., CSA, CAD, CSM, CTA)

Who You'll Work With

You will join an existing Agile squad comprised of engineers, analysts, a product owner, and scrum master. You will report to the ServiceNow Chapter Lead and will work closely with the product owner and scrum master to shape and prioritize your work each sprint, as well as with architects and other chapter members to keep solutions aligned across the platform.
