Staff Software Engineer

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.

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

• Mentor engineers, raise the quality of technical decision-making, and help the team execute with consistency
• Establish coding standards, review practices, and architectural documentation that scale as the team grows
• Partner with recruiting to build and grow the team

Collaborate Cross-Functionally

• Work closely with product, design, QA, and customer support to translate requirements into executable technical plans
• Participate actively in design reviews and roadmap discussions with a grounded, implementation-level perspective
• Handle most cross-team conflicts and technical decisions autonomously

Operational Excellence

• Own monitoring, diagnosing, and resolving production issues within your team's services
• Use observability tooling to measure and improve system performance and reliability
• Implement and uphold best practices that maximize developer productivity across the team

Domain Expertise

• Grow into a subject-matter expert in your domain, with an in-depth understanding of customer needs and the value your systems deliver
