Because together, we have the power to create extraordinary outcomes for our customers, our communities, and ourselves.

Who we are looking for:

We are hiring a senior-level full-stack Software Engineer to join our Leasing Engineering Team and drive our rapid product development pace. We work collaboratively to define the technical direction for our SaaS products, developing high-quality, easy-to-use solutions for our customers. Our engineers take pride in delivering solutions that meaningfully impact customers and raise the technical bar for the organization. We balance pragmatism with excellence—delivering value quickly while ensuring systems are reliable, scalable, and maintainable.

This is an ideal opportunity for someone who is passionate about building leading-edge software, thrives on solving complex technical problems, and wants to play a key role in shaping the success of a SaaS product used by thousands of businesses. We foster an environment that empowers small teams to take ownership, set the technical vision, and lead through impact.

Responsibilities:

• Develop scalable, resilient, and elegant web-based solutions to solve complex business problems at scale.

• Lead by example in design, coding, and architecture; mentor and coach other engineers to raise the technical bar across the team.

• Formulate, implement, and optimize algorithms and database queries to ensure SaaS scalability, performance, and stability.

• Design and deliver new features and improve existing ones with a focus on robustness, maintainability, and performance.

• Drive engineering excellence through test-driven development, thoughtful code reviews, and continuous integration practices.

• Collaborate deeply with engineers, QA, product managers, designers, and researchers to deliver end-to-end solutions.

• Champion agile practices that emphasize collaboration, prioritization, urgency, and accountability to deliver at a rapid pace.

• Proactively research, share, and apply new technologies and patterns that improve system quality and accelerate delivery.

You know you’re the right fit if…

• You have 5+ years of experience developing and scaling web-based applications, preferably in a SaaS environment.

• You are comfortable working across all levels of the development stack and excel at breaking down complex problems.

• You have experience leading technical projects end-to-end—from shaping requirements and architecture through implementation, launch, and ongoing optimization—while aligning stakeholders and ensuring successful outcomes.

• You have experience with modern Agile software development practices (Scrum, Kanban, CI/CD).

• You have strong experience with automated testing and understand its role in sustainable engineering.

• You are language agnostic and have deep experience with at least one modern language such as Ruby, Java, or Python.

• You take a pragmatic approach to technology—adopting new tools where they add value, while mastering proven technologies.

• You care about long-term maintainability, advocate for clean architecture, and drive continuous refactoring and improvement.

• You balance intensity and sustainability—you’ll go the extra mile when needed but also model healthy work-life balance.

Nice to Have:

• Bachelor’s, Master’s, or Ph.D. in Computer Science or related technical discipline.

• Experience with technologies in our stack such as Ruby on Rails, React, AWS, or service-oriented architectures.

• Experience with AI/ML technologies and how they integrate into SaaS applications.

• Experience leading architectural discussions, defining system design, and guiding technical decision-making.
