We’re looking for an experienced Engineering Manager to lead a platform-focused team responsible for building and operating critical infrastructure systems. This role blends people leadership with strong technical judgment, ownership of complex systems, and close collaboration with product and engineering partners.

You take clear ownership of your team’s systems and outcomes. You help translate broader platform direction into actionable technical plans, make thoughtful tradeoffs, and ensure your team consistently delivers reliable, scalable solutions.

You help your team connect platform work to real customer outcomes. You set clear priorities, balance reliability and velocity, and ensure the team is focused on the platform investments that most effectively support product teams and customers.

You encourage your team to question assumptions and improve existing systems. You balance best practices with pragmatism and help the team move forward without over-engineering or unnecessary risk.

• Support your team through clear goal-setting, regular feedback, career development, and thoughtful hiring
• Partner closely with staff engineers and product managers to plan and execute platform initiatives that improve scale, reliability, and developer productivity
• Drive technical execution for distributed systems that process large volumes of events with strong performance and availability requirements
• Guide architectural decisions within your team, aligning with broader platform standards and long-term direction
• Ensure your team’s services are observable, well-tested, and operationally sound
• Lead incident response for your team’s systems and foster a culture of learning and improvement through effective post-incident reviews
• Collaborate with adjacent engineering teams, security, and product partners to ensure platform work supports company priorities
• Help improve internal tooling, workflows, and processes that enable engineers to do their best work
• Leverage modern tooling—including AI-assisted development tools—where appropriate to improve team efficiency and focus

• 8+ years of professional software engineering experience, including experience building and operating large-scale distributed systems
• 3+ years of experience managing engineers, including hiring, coaching, and performance development
• Strong technical background with the ability to lead design discussions, review complex systems, and make sound architectural tradeoffs
• Experience working with cloud infrastructure (AWS or GCP) and modern backend systems
• Familiarity with distributed systems concepts such as asynchronous processing, event-driven architectures, and data pipelines
• Proven ability to deliver meaningful technical projects through a team
• Clear and effective communication skills, with the ability to explain technical concepts to both engineers and non-engineers
• Comfort balancing people leadership with hands-on technical involvement
• Strong judgment around prioritization, execution, and reliability in ambiguous problem spaces

• Experience at high-growth SaaS companies
• Exposure to messaging systems, data pipelines, or high-throughput backend services
• Experience improving developer tooling or platform ergonomics
• Familiarity with AI/ML tooling or infrastructure
