Tech Lead - Sr. Software Engineer

Tech Lead - Sr. Software Engineer

In this role, you'll mentor the project team, share knowledge, and collaborate with the Solution Architect to determine project architecture. You'll lead in developing projects, promoting best programming practices, and have influence over developers. Lastly, you'll provide application support, develop and document applications, and maintain application documentation and configuration.

As a Tech Lead Software Engineer, you are a hands-on technical leader with end-to-end ownership of service-level architecture, delivery outcomes, and production reliability. You set technical direction, make and communicate clear architectural tradeoffs, and lead through influence—aligning engineers, product, and partners around durable, scalable solutions. You design, build, and operate backend services as the organization modernizes from on-prem to AWS, applying cloud-native and event-driven patterns to improve reliability, security, and developer velocity. You champion build-it/run-it ownership, ensuring services meet clear standards for quality, observability, and operational excellence. You accelerate delivery through AI- and agentic-first engineering practices, establishing safe, repeatable workflows that improve throughput and quality while maintaining strong validation, security, and governance. You raise the engineering bar by mentoring others, setting clear guardrails, and continuously improving the systems and practices your teams rely on.
