About HappyCo
HappyCo builds modern property management software that helps owners and operators deliver better living experiences at scale. As we continue to evolve our platform, we are entering a period of significant architectural transformation—modernizing legacy systems while expanding into AI-orchestrated, event-driven workflows that will define the next generation of our product.
The Role
HappyCo is seeking a Principal Software Engineer to lead architectural design and technical strategy during a pivotal phase of platform evolution. This role will be responsible for creating clarity where complexity exists—assessing current systems, defining target architectures, and enabling teams to move faster through well-documented patterns and simplified software structures.
As HappyCo transitions from AI-augmented capabilities to agentic, AI-orchestrated, and event-driven workflows, this role will provide the architectural oversight and long-range planning required to evolve the platform without disrupting customers. You will be a key driver of technical debt reduction and platform modernization, ensuring that engineering teams—both internal and external—can deliver high-quality work efficiently and consistently.
In your first few months, you will develop a comprehensive view of HappyCo’s existing architecture and translate that understanding into a clear, actionable roadmap for change. Your work will directly improve engineering velocity by replacing fragmented or legacy approaches with shared, documented patterns that teams can confidently follow.
Responsibilities
- Architect and design platform systems and services for enterprise-scale SaaS software, with an emphasis on scalability, resilience, and long-term maintainability.
- Assess existing architectural patterns and system designs across the HappyCo software suite, identifying opportunities to reduce technical debt and simplify complexity.
- Define and document target architectures, guiding principles, and standards that enable teams to build faster and more consistently.
- Develop architectural proposals, technical plans, and RFCs, and guide them through internal review and decision-making processes.
- Lead Technical Design Reviews for Staff Engineers and Tech Leads, ensuring alignment with documented patterns and platform direction.
- Drive platform modernization initiatives, including the deprecation of legacy systems in a way that minimizes risk and customer impact.
- Provide hands-on technical leadership by contributing POCs, reference implementations, and other artifacts that accelerate shared understanding and adoption.
- Enable and support external software teams by providing clear documentation, repeatable processes, and timely, decisive architectural guidance.
- Act as a trusted technical advisor to PDE leadership, promoting and evangelizing architectural direction and best practices across the organization.
What We’re Looking For
- Deep experience designing and evolving complex, production-grade SaaS platforms.
- A strong track record of leading architectural change while maintaining system stability.
- Expertise in modern software architectures, including event-driven systems, service orchestration, and platform design.
- Demonstrated ability to reduce technical debt in ways that measurably improve team and organizational velocity.
- Excellent communication skills, with the ability to influence across teams and levels of seniority.
- Comfort operating in ambiguous problem spaces and making high-impact technical decisions.
Why HappyCo
- A rare opportunity to shape the technical foundation of a growing SaaS platform during a major architectural transition.
- High-impact role with visibility and influence across engineering and product leadership.
- Collaborative engineering culture that values clarity, pragmatism, and continuous learning.
- Competitive compensation, benefits, and flexible work arrangements.
