About your role

As a Senior Software Engineer at Juniper Square, you're a hands-on individual contributor who designs, builds, and operates production systems powering core workflows for institutional financial clients. You bring deep technical expertise to your team, drive complex projects independently, and collaborate closely with Staff engineers, product, design, and QA to ship reliable, well-designed systems.

You'll join the Platform team, building the foundational infrastructure layer that powers all AI work at Juniper Square, both customer-facing (GPX) and internal automation. Every AI initiative at JSQ runs on top of this platform, spanning AI Gateway & Infrastructure, Governance & Security, Retrieval & Data Access, and Agent Framework.

What you'll do

Build & Operate Production Systems

• Design, build, and ship production-quality systems, APIs, and services - from foundational platform capabilities to customer-facing product experiences

• Own projects end-to-end: translating requirements into technical designs, implementation, testing, deployment, and ongoing iteration

• Build reliable, scalable, and observable systems that deliver value to customers and enable other engineering teams to move faster

• Own the production health of the systems you build, including monitoring, troubleshooting, performance, reliability, and issue resolution

• Build reusable infrastructure, frameworks, tooling, and developer experiences that enable teams across the organization

• Improve engineering velocity and operational quality through automation, documentation, and continuous improvements

Drive Technical Excellence

• Contribute to technical design for complex projects, evaluating tradeoffs and proposing pragmatic implementation plans

• Partner with product, design, and engineering to translate requirements into well-designed technical solutions

• Help identify and reduce technical debt, reliability risks, and friction in the software development lifecycle

• Collaborate with Staff and senior engineers to establish reusable patterns and raise engineering standards

• Participate in code reviews, design reviews, debugging, incident response, and operational support

AI Fluency & AI-Native SDLC

• Use agentic coding tools and AI-assisted development as a primary part of your workflow, deliberately choosing where AI versus traditional software is the right tool

• Critically evaluate AI-generated code for correctness, edge cases, and regressions, shipping quality output regardless of how it was produced

• Build or integrate AI/LLM-powered capabilities in your domain where they add real value (e.g., evaluation frameworks, RAG pipelines, agentic workflows), with clear human-in-the-loop boundaries

• Contribute to the team's evolving practices around AI-accelerated development, testing, and code review

Collaborate Cross-Functionally

• Work closely with product, design, QA, and cross-functional partners to meet timelines and align solutions to business goals

• Provide clear, accessible technical context to both technical and non-technical stakeholders

Domain Expertise

• Grow into a subject-matter expert with a deep understanding of the data, workflows, and customer needs specific to that space

Qualifications

Required

• 7+ years of experience in backend and/or full-stack software engineering

• Strong backend engineering experience with Python and frameworks such as FastAPI, Flask, Pyramid, or Django

• Experience with relational/NoSQL databases, including schema design, query optimization, and data modeling

• Experience with cloud-native technologies such as AWS, Docker, and Kubernetes, and infrastructure as code

• Strong understanding of CI/CD, observability, and operating services in production

• Comfort working full-stack when the problem calls for it (TypeScript/React experience a plus)

• Ability to break down complex technical problems and deliver pragmatic, maintainable solutions

• Strong ownership mindset, with the ability to drive projects independently while collaborating effectively across teams

• Clear communication skills, with the ability to explain technical tradeoffs to engineering and cross-functional partners

• Hands-on experience with AI-native development tools (e.g., Cursor, Augment), and demonstrated AI Fluency: a deliberate point of view on when AI is (and isn't) the right tool, adapted code review practices for AI-generated code, and safeguards against over-reliance on AI tooling

• Bachelor's degree in Computer Science or equivalent work experience

• Hands-on experience building or integrating AI/LLM-powered systems in production (e.g., RAG pipelines, agent frameworks, evaluation workflows, guardrails, prompt/tool orchestration, or model observability)

• Comfort operating in ambiguous, fast-evolving technical territory where best practices and patterns are still being established

Nice to Have

• Background in financial services or fintech

• Experience with API gateway/infrastructure, security & governance tooling, retrieval and data-access systems, or agent frameworks at production scale

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.
