Senior Software Engineer II (Hybrid)

Hi, Future Homie! At Homebase, you’ll join a team that’s bold, fast-moving, and obsessed with helping small businesses thrive. We build with empathy, act with urgency, and take big swings that drive real-world impact. Here, every Homie shows up to raise the bar, support one another, and celebrate wins as a team. We’re not just building an app—we’re building unstoppable teams. So what do you say, are you in? Your Impact Starts Here As a Senior Software Engineer II on our Identity & Notifications team, you'll own the systems that power Homebase's "Passport to Work" vision — the unified identity layer that follows a user across their entire work journey. That means authentication, authorization, role modeling across complex multi-tenant contexts, and the notification infrastructure that keeps workers and business owners informed, in real time, without noise. This is a high-ownership, high-visibility platform role. You'll be shaping how identity works at Homebase for the next decade — and building the notification rails that connect millions of people to the moments that matter. These are the key ways you’ll contribute and create impact in this role: Own identity end-to-end. Design and build the systems that manage user authentication, session lifecycle, and authorization across Homebase's multi-role, multi-employer context. One user. Many states. Zero confusion. Model complex authorization. Lead the design of role-based and attribute-based access control (RBAC/ABAC) systems that reflect the real-world complexity of how small business teams work — managers, employees, owners, and everything in between. Build notification infrastructure that scales. Design and operate the backend systems powering push, email, and in-app notification delivery — reliably, at scale, with intelligent routing and preference management. Drive architectural decisions. Write the RFCs, lead the design reviews, and set the technical direction for your domain. Your decisions establish the standard. Ship with velocity. Break down ambiguous problems fast, make high-quality calls you stand behind, and get working systems into production without waiting for perfect. Build with AI. Actively integrate AI tooling into your engineering workflow — from code generation and security review acceleration to intelligent notification personalization and abuse detection. Retool how the work gets done, and show the impact. Elevate the team. Mentor peers, share knowledge generously, and raise the bar in every design review and code review you touch. Collaborate across the stack. Partner with Product, Security, and feature-domain engineering teams to deliver identity and notification capabilities that unlock the rest of the platform roadmap. The Foundation for Success - These are the experiences and strengths that will set you up for success in this role: Retool your workflows using AI-powered development tools (e.g., Copilot, Cursor, LLM-assisted code review and security analysis). Measure the impact — faster cycle times, reduced auth incident MTTR, improved notification deliverability. You can speak to what changed and why. Experiment actively with emerging AI applications relevant to identity and notifications — anomaly detection, intelligent delivery timing, abuse pattern recognition. Participate in team-wide AI fluency sharing — what's working, what's not, and what's next. 5+ years of backend engineering experience with meaningful ownership of production systems at scale. Deep expertise in identity systems — authentication protocols (OAuth 2.0, OIDC, SAML), session management, token lifecycle (JWT, refresh tokens, revocation), and authorization modeling (RBAC, ABAC, or policy-based access control). Experience designing multi-tenant identity models — ideally in contexts where a single user holds multiple roles across multiple organizations or employment states. Hands-on experience building or operating notification infrastructure — delivery pipelines, fan-out architecture, user preference management, and multi-channel routing (push, email, in-app). Strong command of at least one backend language (Ruby, Go, Python, or similar) and relational database design. Track record of leading technical design — writing RFCs, driving alignment across teams, and executing through real ambiguity. Active AI fluency: you use tools like GitHub Copilot, Cursor, or LLM-based assistants to meaningfully accelerate your workflow, and you can speak to the measured impact. Security-minded by default — you think about identity and notification systems through the lens of abuse, spoofing, privilege escalation, and data privacy before they become incidents. Clear, direct communicator who can translate system complexity into decisions stakeholders can act on.
