Join our Tax Technology and Transformation team as an Engineering Senior Manager, where you will be part of a technology organization that develops and maintains innovative solutions for our client-serving Tax professionals. You will have the opportunity to partner with our tax professionals to develop supporting technology such as digital/mobile tools to improve internal operations, application of Robotics Process Automation (RPA) to collect financial data, development of advanced financial dashboards, visualization, analytics, and reports.

Your key responsibilities

As an Engineering Senior Manager, you will be responsible for leading multiple teams working on several related products within our ecosystem. This is a deeply technical role that requires close interaction with architecture, technical leads, and senior leadership. The ideal candidate will have a strong background in modern development practices, infrastructure as code, developer effectiveness, and ownership of the full development loop. Python is now a required backend skill: while we continue to support and evolve existing .NET/C# services, new backend development is focused on Python. On the frontend, we are moving away from Angular and shifting toward Next.js and Web Components. Macrocomponents remain a core pattern, now implemented with Web Components and Module Federation. As agentic SDLC gains broad traction, the candidate must also bring practical experience applying it in real engineering delivery.

Your responsibilities will include:

• Lead and manage 1–3 teams, aligning to organizational goals, fostering collaboration, and contributing technical depth as needed
• Stay close to delivery by reviewing code, contributing where needed, and managing the tech debt backlog
• Serve as the technical decision point, providing guidance and supporting troubleshooting and issue resolution
• Plan, sequence, and prioritize teamwork; identify dependencies early and keep teams focused on goals
• Set weekly/sprint goals, drive demos, and prepare demo scope and dry runs
• Break down work into achievable increments, tracking milestones and risks to maintain predictable delivery
• Uphold and apply engineering principles consistently, guiding team decision-making and ensuring high-quality delivery
• Lead practical adoption of agentic SDLC with clear human-in-the-loop quality, testing, and security guardrails
• Drive excellence across the full development lifecycle: design, coding, testing, release, operations, and continuous improvement
• Track and report key metrics, including updates to Atlassian Compass, ensuring transparency into progress and performance
• Organize and oversee live iteration demos, ensuring they are conducted from cloud environments and not skipped
• Own InfoSec responsibilities by maintaining an up-to-date issue list, addressing findings early, and adhering to remediation timelines
• Lead implementation of strategic initiatives aligned to organizational goals
• Ensure technical documentation is accurate, up to standard, and treated as a required deliverable with clear expectations

Skills and attributes for success

• Proven experience in leading engineering teams and delivering complex technical projects
• Strong proficiency in Python for backend development, with experience maintaining and evolving existing .NET/C# services
• Strong frontend experience with Next.js, Web Components, and Module Federation; experience migrating from Angular and legacy microfrontend approaches is highly valuable
• Extensive experience with cloud-native applications on Azure (AWS and GCP experience is also acceptable)
• Hands-on experience with containerized workloads and orchestration
• Proficiency in Infrastructure as Code (IaC) tools such as Bicep, Terraform, Pulumi, or CDK
• Full-stack development experience with a focus on modern frameworks (React is acceptable)
• Demonstrated hands-on experience with agentic SDLC in production delivery workflows
• Proven ownership of the development loop (build, test, release, operate, and iterate)
• In-depth knowledge of test automation (unit, integration, e2e)
• Demonstrated ability to solve complex technical problems and make significant technical contributions
• Excellent communication skills and the ability to articulate technical concepts to non-technical stakeholders
• A passion for technology and continuous learning, with personal projects or interests outside of regular work

To qualify for the role, you must have

• Bachelor’s degree required (4-year degree) Accounting, Finance, Information Systems, Economics and/or a master’s degree in Accounting, Tax Technology, Management Information Systems, or Computer Science or related field; master's degree preferred.
• A minimum of eight years of relevant experience

• You are required to have one of the following certifications: CPA, EA, JD, Master’s degree in business administration, finance, economics, computer science, information systems or engineering, Quantitative Economics or Quants
• Exposure to the financial services industry, accounting/finance/tax, tax or finance performance improvement, tax software development and/or implementation 

• Ability to take ownership of assigned tasks and monitoring them until completion, including documenting requirements, configuration, testing, debugging, project profitability, and tax systems and process configuration

Ideally, you’ll also have

• Familiarity with delivery tools such as GitHub, GitHub Actions, Atlassian Suite, SonarQube, Mend, and Aqua Trivy
• Strong understanding of component life cycles, unit testing, and resolving complex issues in full-stack development
• Professional certification requirements as defined by each service line
• Emotional Agility and Hybrid Collaboration skills
• Experience in Leading Teams and Learning Agility

What we look for

We are looking for top performers who demonstrate the ability to be client-focused, results-driven, and innovative. You should possess strong leadership skills, the ability to think critically and solve complex problems, and a passion for delivering high-quality user experiences.
