Senior IT Engineer

Are you ready to be a part of something groundbreaking? Mainstay is the leading market intelligence platform purpose-built for buying, managing, and selling homes in the single-family rental industry. We empower informed decision-making and unlock opportunities for owners, operators, and residents by aggregating and standardizing data from over 50 unique sources. Originally founded within Opendoor, Mainstay launched as an independent company in 2024, driven by our mission to simplify the complex and bring clarity and trust to the single-family rental ecosystem. Join us as we reshape the future of the industry!

We’re looking for a Senior IT Engineer to jump in on two high-priority projects: migrating Mainstay to its own Slack workspace and standing up a secure authentication system (most likely Okta). This work is part of our ongoing transition away from Opendoor, and both systems need to be in place over the next few months.

This is a hands-on, full-time contract role expected to last 3 to 6 months. You’ll lead these projects end to end, from planning and configuration to rollout and communication – working closely with key stakeholders across the company.

In this role, you will:

• Set up and launch a new Slack workspace for all Mainstay employees, including user provisioning, channel structure, and integrations

• Stand up a secure authentication solution with multi-factor authentication and identity management, including integrations with tools like Google Workspace and Rippling

• Help coordinate change management and communications for both rollouts

• Pitch in on related IT tasks as needed during the transition

• Has 6+ years of IT experience, ideally with a mix of system administration, SaaS tools, and infrastructure projects

• Has implemented Okta or a similar IAM solution from the ground up

• Knows their way around Slack migrations, Google Workspace, Jamf, Apple Business Manager, and Rippling

• Can troubleshoot and figure things out without a lot of hand-holding

• Communicates clearly and works well with both technical and non-technical teammates

• Thrives in a fast-paced, remote-first environment

Mainstay’s compensation varies by U.S. geographic market to align with local labor costs. For most locations, the pay range for this position is $53 – $70 per hour, while the hourly range for roles based in the SF Bay Area, Seattle, and New York City Metro area is $66 – $77. Pay is based on location, skills, and experience, and your recruiter will confirm the specific range for your job location. Please note that remote roles are available in all U.S. states except Hawaii, Alaska, Montana, and U.S. Territories.
