Software Engineering Manager III - Core Services

onXmaps, Inc. is a high-growth tech company focused on helping people explore the outdoors through technology. They are seeking a Software Engineering Manager III to lead engineering teams responsible for core data infrastructure and delivery systems that support their suite of apps, ensuring operational excellence and fostering team development.

Responsibilities:

• Make great engineers better. You'll support your teammates with individual goal-setting, professional development, and mentoring. You'll coach engineers through structured growth plans and partner with senior/staff-level ICs to set technical direction for the teams
• Make great software. You'll work with your teams to ensure you're delivering maintainable, high-quality platform systems that internal and external customers depend on. You will lead your teams in design, development, testing, deployment, and operations, with a focus on reliability and developer experience
• Build great teams. You'll work closely with your peers to hire smart, creative, and kind engineers. You'll be responsible for building and sustaining a healthy team culture where ownership and collaboration are the norm
• Own operational excellence. You'll establish and maintain production reliability practices including SLO definition and monitoring, incident management, on-call sustainability, and postmortem culture
• Collaborate. You'll manage dependencies between functional teams and facilitate collaboration across engineering, Product, Product Design, and business stakeholders. Your teams build foundational capabilities used across onX's apps, making cross-functional alignment critical
• Lead through others. You can drive a project yourself or direct teams and technical leaders to a desired outcome. You provide thought partnership for your team, challenging and elevating your team to develop robust architectural and technical strategies
• Translate. You'll translate business strategy, customer insights, and organizational priorities into clear engineering direction, helping your team understand the "why" behind the roadmap and how their work connects to onX's goals

• A shared passion for and ability to demonstrate onX's Company Values

• (When applicable) This position requires that a portfolio of work samples be submitted for consideration
• Experience with data systems architecture, GraphQL federation, or distributed systems
• Familiarity with mapping, geospatial, or navigation technologies
• Experience designing or leading complex server-side architectures for high-volume consumer-facing products
