About the role

We’re hiring two Senior Ops Design & Strategy Associate - one to support our HOA product and one to support our Tax product. Both products are core to Mainstay’s platform, which serves institutional single-family rental investors managing thousands of homes across fragmented markets.

Each associate will play a critical role in shaping how their product operates and scales - partnering with Product, Engineering, and Operations to design the systems, processes, and insights that make our platform seamless for customers. Whether you’re optimizing collection of dues across hundreds of HOAs or streamlining the processing of millions of dollars in property tax payments, your work will transform complex, manual processes into efficient, data-driven systems.

In this role you will

• Own performance outcomes for either the HOA or Tax product line, identifying friction in workflows and driving improvements that make the system faster and more reliable

• Facilitate building models and dashboards to diagnose performance trends and guide data-driven decisions

• Partner with Product Managers to translate operational insights into feature ideas and process changes that improve automation, customer experience and scalability

• Create and refine processes that let Mainstay onboard new institutional partners efficiently and operate at scale without unnecessary complexity

• Coordinate with Product, Engineering, and Operations to align priorities, deliver results, and measure impact

• Track and report the results of new initiatives, sharing insights and influencing roadmap and process priorities

• Keep pushing for better by spotting new opportunities, proposing fixes, and taking ownership of getting them implemented

What we're looking for

• 5+ years of professional experience in business operations, business consulting, product operations, project management, sales operations

• A history of solving complex problems quickly and independently - you know how to prioritize, figure things out, and get results

• Strong analytical and technical skills. Excel experience is required. Experience with SQL is highly preferred.

• A process minded approach paired with flexibility - you care about precision but can adapt when things move fast

• Clear, confident communication. You can break down complex ideas and work easily with both technical and non-technical teammates

• A strong sense of ownership and accountability. You move quickly, take initiative, and consistently deliver high quality work

• A bias for action and a “no problem is too small” attitude

Bonus points for

• You have an interest in real estate; residential real estate experience

• Fluency in leveraging AI tools and methods for analysis and process improvement is highly recommended

• Startup experience preferred

This role is a great fit if

• You enjoy turning messy, ambiguous problems into clear systems and processes that actually work

• You’re comfortable operating with limited direction and like taking ownership from idea to execution

• You think in both numbers and narratives - able to analyze data, but also explain what it means for the business

• You like working cross-functionally and can build strong partnerships with Product, Engineering, and Operations teams

• You’re motivated by impact and want to see your work directly improve how a product runs and how customers experience it

• You’re energized by change and growth - you like joining a company in motion

Not a great fit if

• You prefer steady-state environments with fixed processes and long timelines

• You need clearly defined instructions before taking action

• You see your role as “support” rather than “ownership”

• You’re uncomfortable working across different functions or switching contexts quickly

• You value perfection over progress - you’d rather get it exactly right than get it moving
