About the Team & Role

Are you a technical artisan who thrives in collaborative environments

and gets excited about solving the right problems, the right way? Do you believe in breaking down silos and fostering a culture of shared responsibility? Then this role is for you!

In today's software development landscape, collaboration, E2E accountability, problem solving and streamlined workflows are key to achieving efficiency and delivering high-quality solutions that solve customer problems and generate business outcomes. We believe in the power of integrated engineering, where development, quality, and agility skills blend together throughout the solution delivery pipeline. In this role, you'll be a champion for this approach, fostering a culture of shared ownership and breaking down silos to ensure a smooth and efficient flow of innovation to customers.

How you’ll make an impact

Collaborate with stakeholders throughout the SDLC to translate complex business requirements into high-quality, reliable, cost-effective, and maintainable solutions that solve customer problems and generate business outcomes.
Lead the design and development of major systems or constellations of smaller systems with a focus on Continuous Delivery principles and practices.
Champion integrated engineering practices within the organization, defining "Golden Paths" for service communication and cross-team technical standards.
Architect and implement advanced AI workflows, including multi-agent orchestration, state management, and memory persistence to solve high-value business problems.
Solve architectural bottlenecks that cross team boundaries and review designs from other teams for consistency, scalability, and long-term supportability.
Coordinate large-scale programs across many dependent teams, independently creating project plans and managing materializing risks with a high degree of confidence in delivery.
Research and implement new ways to keep teams efficient, staying ahead of industry trends and Agile practices at both the team and enterprise level.
Act as a talent multiplier by mentoring senior engineers, leading by example in code reviews, and fostering a culture of technical excellence.
Serve as the "Adult in the Room" during crises, providing guidance to resolve issues, determining root causes, and implementing systemic changes to prevent repeat occurrences.

Core Skills:

Programming/Software Development: As a Staff Engineer, you are an expert across multiple tech stacks and move freely between them to solve complex hurdles. You set the organizational standard for clean, maintainable code and drive the development of autonomous agentic systems. You are the primary architect for complex systems, ensuring that software is designed not just for immediate features, but for long-term scalability, resilience, and cost-efficiency.
Testing: You drive the organizational strategy for quality by organizing and overseeing a library of regression tests as a shared resource. You balance risk, effort, and coverage by directing regular reviews of environment-specific test suites. You collate feedback from end-users and historical defects to assessment where the most systemic risk resides, focusing engineering efforts accordingly to ensure a high-quality user experience.

Additional Valuable Skills:

Systems Integration: You lead the integration of complex, cross-functional systems and third-party services. You are responsible for identifying and resolving integration bottlenecks that impact multiple product lines or dependent teams. Your role ensures that disparate components align architecturally to maintain a cohesive, resilient, and high-performing ecosystem.
Release and Deployment Management: You define and evolve the deployment strategy to ensure rapid, safe, and consistent delivery across the organization. By automating complex release workflows, you reduce manual effort and increase reliability across the program, managing the critical path for major initiatives spanning multiple dependent teams.
Methods and Tools: You define the technical vision for our tooling landscape, researching and adopting cutting-edge tools that improve decision-making and automate repetitive tasks. This ensures data-driven development and organizational efficiency, keeping the engineering team current in a rapidly evolving field.

Experience you'll bring

Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent experience).
Minimum of 8-10 years of experience in software engineering and delivery, with a proven track record of leading multi-team initiatives.
Expert proficiency in multiple programming languages and modern architectural patterns (Microservices, Event-Driven, etc.).
Hands-on experience building with LLMs and designing multi-agent agentic workflows (handling state, memory, and tool calls).
Strong understanding of continuous delivery principles and mastery of automation tools (e.g., Jenkins, GitLab CI/CD, etc.).
Exceptional problem-solving and analytical skills, with the ability to navigate high degrees of ambiguity.
Excellent communication and negotiation skills, with the ability to tailor messaging for a wide variety of audiences, including senior leadership.
Ability to work independently and as a strategic lead within a cross-functional technical team.
