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: Reporting - Lead the squad that builds the backbone of Juniper Square's financial and web reporting. You'll help set the private-markets standard for customizable, actionable reporting - letting users pull any data, from anywhere, place it anywhere, in any format, and generate the insights that drive decisions. This is a critical, hands-on role for a player-coach who improves systems, automates reporting workflows, enjoys working with financial data, and boosts operational efficiency. 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 Qualifications Required 12+ years of experience in backend and/or full-stack software engineering, with a clear trajectory of increasing technical leadership, architectural responsibility, and mentorship A portfolio of shipped production systems - be ready to walk through specific technical decisions you personally made and code you personally wrote; this is not a role for someone whose primary contribution has been directing others Deep expertise in at least one server-side language (Python preferred, Node/TS, Java, C++, C#, or similar) and strong proficiency building production-grade backend services Experience with modern front-end frameworks (React preferred) and comfort working full-stack when the problem calls for it Experience with relational/NoSQL databases, including schema design, performance tuning, and data modeling Experience building and operating cloud-native systems using AWS (or equivalent), Docker, Kubernetes, and infrastructure as code Strong understanding of CI/CD, observability, reliability, and operational excellence in production environments Deep understanding of service-oriented architecture and experience evolving systems from monolith toward SOA Demonstrated ability to raise engineering quality through technical standards, design reviews, mentoring, and reusable platform patterns Hands-on experience with AI-native development tools (e.g., Cursor, Augment) and a track record of using them to accelerate personal and team velocity Demonstrated AI Fluency: hands-on experience building AI-assisted or agentic systems with a deliberate, defensible point of view on when AI is (and isn't) the right tool; adapted code review practices to catch AI-specific failure modes; and concrete safeguards against over-reliance on AI tooling Ability to work through ambiguity, break down complex problems, and drive alignment across engineering, product, and design Bachelor's degree in Computer Science or equ
