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. If you think this role sounds like a fit, we encourage you to apply even if you don't meet every qualification.
