WHAT YOU WILL DO

onX is seeking a Senior Backend Engineer with a passion for building scalable platform Identity and Access Management (IAM) systems. Your focus will be on designing, developing, and scaling secure authentication, authorization, and user management services that are foundational to our platform. You will play a key role in evolving our IAM platform and delivering seamless cross-platform authentication across iOS, Android, and web.

You will be part of our Core Services team that enables product teams to build faster and more securely by providing core infrastructure, services, and patterns. This is a great opportunity to help shape the future of how users securely access and interact with onX's suite of outdoor technology products.

This position reports to the Director of Engineering, Core Services.

TECHNOLOGIES WE USE

Our backend engineers primarily work in Go running in Kubernetes on Google Cloud Platform. The IAM team works extensively with identity platforms (Ory Kratos, Hydra, Oathkeeper), distributed databases (CockroachDB), and OAuth 2.0/session management patterns. Understanding mobile authentication tradeoffs (WebView vs. browser-based auth, token-based patterns) is particularly relevant for this role.

As an onX Senior Backend Engineer, your day to day responsibilities would look like:

(Essential Job Duties)

• Build scalable, secure IAM services that enable new features and products across the onX suite of apps
• Design and implement backend systems focusing on observability, fault-tolerance, security, and high performance
• Drive architectural decisions related to Identity and Access Management, ensuring alignment with and advancing our broader platform strategy
• Define and implement SLIs/SLOs for IAM services; drive reliability engineering practices including incident response and performance optimization
• Write thorough unit, integration, and acceptance tests to ensure high service quality and maintainability
• Document APIs, service architectures, and technical decisions for internal stakeholders and external partners as needed
• Collaborate closely with fellow engineers, product managers, and other stakeholders through design reviews, paired programming, and cross-functional planning sessions
• Leverage and extend existing onX services and platform patterns to drive consistency and reduce duplication
• Proactively improve system monitoring, alerting, diagnostics, and operational readiness of IAM-related services
• Participate in an on-call rotation to ensure backend services remain highly available and reliable
• Mentor and share knowledge with engineers on your team
• Lead by example and embody onX's company values, fostering a culture of technical excellence, ownership, and collaboration
