We also have physical offices in San Francisco, New York City, Mumbai and Bangalore for employees who prefer to work in an office some or all of the time. About your role As a Staff Software Engineer at Juniper Square, you are a technical leader - setting technical direction, driving architectural decisions, and raising engineering quality across your team. This is a player-coach role: you lead through code and architecture, not just direction. You'll write production code as a hands-on individual contributor while owning your team's technical strategy, roadmap, and growth, and you'll collaborate closely with product, design, and QA to turn complex workflows into delightful, intuitive experiences. We're hiring a Staff Software Engineer for the following team: • Treasury: Join the team building Juniper Square's Treasury platform, the system that brings transactions, balances, and bank data into and across the platform. You'll work on expanding bank integrations, a visualization and reporting layer for payments and treasury data, and vendor exports that connect treasury data to accounting, on a team that has already processed $500M+ in transactions. What you'll do Own Technical Direction & Architecture • Set the technical direction and own the architecture for your domain's systems, from design through production • Lead technical design for ambiguous, cross-functional initiatives - evaluating tradeoffs, aligning stakeholders, and driving implementation • Be instrumental in your team's transition from monolith to service-oriented architecture • Evaluate and select technologies with a bias toward what ships well and scales sustainably Build & Deliver • Write production code as a hands-on individual contributor - this is not a role that delegates implementation to others • Own end-to-end delivery of roadmap projects: design, coding, testing, and production • Manage your team's short-term roadmap (spanning the next two quarters), proactively surfacing execution, cost, and technical risks and driving pragmatic mitigation • Lead the development of complex, full-stack workflows, working across frontend and backend engineers AI Fluency & AI-Native SDLC • Practice AI Fluency across the full software development lifecycle - deliberately choosing where AI versus traditional software is the right tool, and defending those tradeoffs against real criteria (latency, accuracy, cost, data sensitivity, explainability) • Champion and embed AI-native development practices and tools (e.g., Cursor, Augment) to drive significant productivity gains across your team • Adapt code review and testing practices for an AI-assisted SDLC - catching AI-specific failure modes (hallucinated dependencies, overconfident but incorrect logic) before they ship • Build and evaluate agentic workflows and AI-assisted systems where they add real value, with clear human-in-the-loop boundaries and monitoring for failure • Guard against over-reliance on AI tooling, in your own work and in the code you review, balancing velocity with system comprehension and accountability for outcomes • Foster a culture of rapid iteration, high velocity, and quality, and help raise AI fluency across the team Lead & Grow the Team •
