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 • 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 equivalent work experience Nice to Have • Reporting: experience with data integration platforms, ETL/ELT processes, business intelligence tools, or financial data • Production experience building AI/LLM-powered systems (RAG pipelines, agentic workflows, evaluation frameworks) • Background in financial document processing or fintech data pipelines • Prior experience in a technical lead or TLM capacity on a new or early-stage product team At Juniper Square, we believe building a diverse workforce and an inclusive culture makes us a better company.
