About Juniper Square

Private markets are one of the largest, most complex, and most underserved corners of global finance. Our mission at Juniper Square is to unlock their full potential. We’re the Operations Partner trusted by 2,300+ GPs, unifying technology, data, and fund administration services into a single platform that helps GPs move faster, make better decisions, and scale with precision. With $300B+ under administration and 700,000+ LPs on platform, we’ve built the scale to match our ambition. And with JunieAI, our purpose-built AI platform, we’re reimagining how private markets operate, embedding intelligence across every workflow. Founder-led since 2014, backed by $350M+ in funding, and now 1,000+ employees strong, we’re building a company designed to shape the future of private markets for decades to come.

Our culture is built for people who want to do ambitious, meaningful work alongside exceptionally talented teammates. We think like owners, move with urgency, and take pride in solving hard problems that truly matter to our customers and the future of private markets. We believe the best ideas come from open debate, deep collaboration, and diverse perspectives, which is why we believe transparency is the default and feedback makes us stronger. If you’re energized by high standards, rapid growth, and the opportunity to help define a category at a pivotal moment, come join us!

Juniper Square offers employees a variety of ways to work, ranging from a fully remote experience to working full-time in one of our physical offices. We invest heavily in digital-first operations, allowing our teams to collaborate effectively across 27 U.S. states, 2 Canadian Provinces, India, Luxembourg, and England. 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 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.

We're hiring Senior Software Engineers across four teams:

Accounting - Join the team that owns Juniper Square's core accounting data and workflows - the bedrock that other product areas build on. You'll work on the transactions platform, expand third-party integrations, build out custom financial and general ledger reporting, and help build a proprietary waterfall model from the ground up, as the platform evolves from a reporting engine into a full accounting engine.

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.

Platform - Join the team building the foundational services every product team at Juniper Square builds on - identity and access management, authorization, search, API infrastructure and the developer experience that determine how fast and how well the rest of engineering can ship.

Dex - Join Dex, Juniper Square's AI-native data warehouse - a customer-facing data product. You'll work on data extraction, built on the existing architecture and running an Ingest → Parse → Classify → Extract pipeline - owning the initial MVP agents and covering structured data extraction, a RAG pipeline, vectorized storage, and a docs repo.

What you'll do

Build & Operate Production Systems

Design, build, and ship production-quality backend services, APIs, and platform components used across multiple teams

Own projects end-to-end: design, implementation, testing, and deployment

Improve the reliability, scalability, observability, and operational quality of the systems you own

Own production health for your systems, including monitoring, troubleshooting, and issue resolution

Build internal tools, frameworks, automation, and documentation that improve developer productivity

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 in your domain (Accounting, Treasury, AI Platform, or Dex), 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 for Accounting and Treasury work)

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

Nice to Have

Accounting: accounting or financial domain expertise or background; economics education

Treasury: experience with bank integrations (Plaid, Yodlee, Wave, QuickBooks, Intuit, FreshBooks); GraphQL

AI Platform: experience building or integrating AI/LLM-powered systems in production (RAG pipelines, AI SDKs, evaluation workflows, guardrails, prompt/tool orchestration, model observability); background in financial services or fintech

Dex: strong data warehousing or data engineering expertise (Redshift, Snowflake, BigQuery, Databricks); experience shipping
