Nice to Have Skills & Experience

Hands-on Auth0 experience. Experience with CIAM / Identity and Access Management platforms.

Experience with commerce, billing, payments, fulfillment, entitlements, subscriptions, or product provisioning. Experience integrating with Oracle or other enterprise commerce/billing platforms. Experience consolidating multiple authentication or commerce experiences into a shared enterprise platform.

Job Description

We are seeking a Principal Software Engineer to join a platform engineering organization responsible for building shared services used across multiple aviation products and applications. This individual will focus on modernizing and integrating two key areas: Customer Identity & Access Management (CIAM) and Commerce/Billing. Today, individual products have different authentication, provisioning, billing, and customer experiences. The goal is to create scalable shared capabilities that provide customers with a more seamless experience across products. This is a hands-on engineering role for someone who enjoys solving complex platform and integration challenges. The ideal candidate has a strong software engineering background and experience building cloud-based platforms, APIs, authentication systems, or commerce solutions.

Key Responsibilities

Design and build shared platform services supporting multiple products and applications. Help create a unified SSO and customer identity experience across products that currently have separate authentication processes. Build software and services that integrate with CIAM platforms such as Auth0. Develop cloud-native applications and services hosted in AWS. Design and develop APIs and integrations between identity, commerce, billing, provisioning, and product systems. Help modernize commerce workflows so products can move toward a more consistent purchasing, billing, and fulfillment experience. Integrate with existing Oracle-based commerce/billing systems through APIs. Provide principal-level technical leadership while remaining highly hands-on with architecture, design, and coding. Partner with engineering teams across different products to identify reusable services and reduce duplication. Establish scalable engineering patterns focused on reliability, security, maintainability, and long-term platform reuse.

This role will pay between $200,000 and $210,000 per year.
