You will play a pivotal role in shaping the user experience, ensuring seamless performance, and driving customer engagement.  You will have the opportunity to take a project team from “zero to one” by leveraging your aptitude for navigating ambiguity and your experience working within a service-oriented architecture.

We’d love to hear from you!

  • Take ownership of building full-stack (with a front-end tilt) flexible, test-driven software that minimizes tech debt and enables change

  • Support, monitor, and maintain integrations with industry-leading third-party platforms

  • Shape API-driven services that are secure, compliant, and highly auditable

  • Enable an experience that is fully internationalized and localized for a global customer base

  • Promote engineering excellence through technical leadership, knowledge-sharing and mentorship

  • Keep extremely sensitive data compartmentalized and secure

  • Perform other related duties as assigned

How You Will Do Your Work

As a Senior Software Engineer, how results are achieved is paramount for your success and ultimately result in our success as an organization. In this role, your foundational knowledge, skills, abilities and personal attributes are anchored in the following competencies:

Good judgment - the exercise of critical thinking, analyzing and assessing problems and implications, identifying patterns, making connections of underlying issues, understanding risks and developing mitigation strategies, and taking ownership of the outcome.

Resourcefulness - taking a can-do approach, even in the face of obstacles and constraints by assessing what’s in front of you and effectively and efficiently optimizing what you have, whether it's working on something new or thinking about how to do something better.

Teamwork and communication - putting our collective best together through documentation, collaboration, relationship-building, listening, empathy, recruiting, and evangelism.

Influence and leadership - fostering a community of knowledge-sharing, collaboration, mentorship, and forward-thinking.
