This is not a typical full-stack position. We're looking for an exceptional Staff / Principal Engineer who can own complex technical domains, shape system architecture, and lead end-to-end development while remaining 100% hands-on. You will report directly to the VP R&D, work closely with them on technical strategy and architecture, gradually take ownership of architectural responsibilities across the platform, and become one of the company's leading technical voices. Along the way you'll help mayors and other city leaders understand their residents and their city in more effective ways, improving the lives of millions of citizens around the world.

Key Responsibilities
Own complex product domains from architecture through production
Lead end-to-end feature development across frontend, backend, and cloud
Drive architectural decisions and technical direction across the platform
Design and build scalable distributed systems
Design and develop AI-powered capabilities as part of the core product
Work closely with the VP R&D on technical strategy and architecture
Mentor engineers through technical leadership (without people management)
Serve as one of the company's technical leaders, influencing engineering standards and long-term technical strategy

As a Senior Software Engineer on the Cortex Platform Application team, you will be a hands-on technical leader responsible for designing, building, and operating critical backend platform services used across Cortex. This role is for an engineer who can combine deep platform/backend expertise with strong ownership, practical execution, and cross-team influence. You will help build scalable and reliable services, guide technical decisions, improve engineering methods, mentor engineers, and raise the quality of how the team designs, ships, documents, tests, and operates its systems. The team owns a broad set of platform capabilities, including areas such as application configuration, dashboards and reporting infrastructure, metrics, multi-tenant and MSSP infrastructure, log forwarding, notifications, auditing, access and permission engines, filtering and querying infrastructure, and other shared application platform domains. We are looking for someone who is not only strong technically, but also enjoys joining a high-performing team, taking ownership from within, and helping turn strong execution into repeatable engineering practice. A successful candidate will quickly become a trusted part of the team by shipping meaningful work, learning the team's domains, and helping others move faster. Over time, this person will help the team increase delivery capacity while also improving how work is designed, documented, tested, operated, and shared across the organization.
