• Make sure platform services meet strict standards for security, availability, performance, and reliability.
• With the Advantage Platform team, define and build secure integration patterns between B2B and Advantage.
• Specify API contracts, authentication flows, authorization models, and how tenant context travels across distributed systems.
• Coordinate design, build, testing, release readiness, and operational support for shared authentication across platforms.
• Lead and mentor a group of 5 to 8 engineers, and give technical guidance to other engineering groups.
• Lead through code reviews, design reviews, threat modeling, and operational readiness checks.
• Raise the standard for secure coding and platform engineering discipline.

• Experience leading technical work across multiple platforms, engineering organizations, and ownership boundaries.
• Experience leading and mentoring engineers, and influencing teams you do not manage through collaboration and technical credibility.
• Experience turning strategic product or AI goals into secure platform designs and workable delivery plans.
• Comfort with customer-facing work, including support, escalations, and reconciling competing stakeholder views.
• Strong communication and executive presence, working well with Architecture, Security, Product, engineering leaders, customers, and junior engineers.
• Would give you an edge: experience with Azure, AWS, or GCP, plus containerized and orchestrated environments such as Docker and Kubernetes.
• Would give you an edge: experience with Azure SQL.
• Would give you an edge: microservices experience and familiarity with cloud-native security patterns and service-to-service communication.
• Would give you an edge: exposure to DevOps and SRE practices for platform services, including monitoring, alerting, and automation.

Conditions

Full-time position with a U.S. base salary range of $163,380 to $261,410 USD, where individual pay depends on job-related skills, experience, and relevant education or training.

The posted range reflects the expectations in this description. If the company selects someone more or less experienced, it may adjust the responsibilities and will share any revised range during selection.

The role sits on the B2B Platform Engineering, Core Services team and owns the security, identity, and access management that every B2B product relies on.

You will work as a key technical partner to the Advantage Platform organization, setting secure, reusable integration patterns for both platforms.

This is a senior, hands-on role for someone who wants influence beyond one product team, in a highly connected environment on a small team serving a large customer base. You will need to ramp quickly, build trust across groups, and shape shared security services used across the ecosystem.

Candidates who meet only some of the qualifications are encouraged to apply anyway.

• A variable incentive pay component on top of base salary.
• Perks such as flexible work options.
• A full range of benefits, including medical and dental insurance.
