Senior Software Engineer, Data (AI)

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.

We are building a next-generation intelligent data platform for private markets - a greenfield initiative that will reshape how financial data is ingested, normalized, validated, enriched, and distributed across a complex ecosystem. This is a foundational role on a small, high-caliber team working at the intersection of modern data engineering and applied AI.

As a Senior Software Engineer, Data, you will own the end-to-end delivery of core pipeline components: schema mapping, data normalization, validation, enrichment, and distribution to downstream systems. You will write production code every day, work closely with Staff engineers on meaningful architectural decisions, and help build the technical standards and practices the broader team will grow into. This role is for someone who executes with high craft and speed, is fluent in agentic development as a first-class part of their workflow, and wants the challenge of building something genuinely new.

Deliver Core Data Pipeline Components

• Build and ship production-quality implementations of data normalization, schema mapping, validation, enrichment, and distribution pipelines for a net-new intelligent data warehouse

• Write clean, well-tested, performant code across backend services, data pipeline logic, and API integrations

• Take end-to-end ownership of features from design through deployment, with accountability for correctness and reliability in production

Contribute to Technical Architecture

• Work closely with Staff engineers to shape the architecture of a modern, AI-native data warehouse serving institutional financial clients

• Bring thoughtful input on schema design, normalization approaches, and API patterns - and execute those decisions with precision

• Identify and raise technical risks early; propose and implement solutions rather than waiting to be directed

Build and Operate with AI-Native Practices

• Use agentic coding tools and LLM-assisted development as your primary workflow - this is how the entire team operates

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

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

Support Data Quality and Reliability

• Build and maintain data validation checks, monitoring, and observability tooling that keeps pipelines trustworthy at scale

• Participate in on-call and production support, diagnosing and resolving data quality issues quickly and thoroughly

• Write and maintain clear technical documentation for the systems you build

Required

• 4–7 years of software engineering experience, with a track record of shipping production systems end-to-end

• Strong backend engineering fundamentals - backend services, data pipelines, and API design; we will ask you to walk through systems you personally built

• Hands-on experience with data pipeline or data warehouse engineering: ETL/ELT patterns, schema design, normalization, and data distribution

• Production experience building with LLMs - prompt design, model integration, and output validation in real systems

• Fluency with AI-assisted and agentic development workflows; you use these tools daily and evaluate their output critically

• Experience with AWS data infrastructure; Redshift experience a plus

• Strong written communication - able to document technical decisions clearly for engineering and product audiences

• Ability to critically evaluate AI-generated code and outputs, including identifying failure modes and regressions

Preferred

• Experience with RAG pipelines, vector stores (e.g., OpenSearch, pgvector), or document extraction systems

• Background in financial services data - familiarity with fund administration, investment data schemas, or institutional reporting workflows is a meaningful differentiator

• Experience building data products for external customers, not just internal tooling

• Familiarity with evaluation frameworks for AI outputs: deterministic checks, cross-model comparison, or human-in-the-loop review patterns

Compensation for this position includes a base salary, equity, and a variety of benefits. The U.S. base salary range for this role is $185,000 – $225,000 USD. Actual base salaries will be based on candidate-specific factors, including experience, skillset, and location, and local minimum pay requirements as applicable.

Benefits include:

• Health, dental, and vision care for you and your family

• Life insurance

• Mental wellness coverage

• Fertility and growing family support

• Flex Time Off in addition to company-paid holidays

• Paid family leave, medical leave, and bereavement leave policies

• Retirement saving plans

• Allowance to customize your work and technology setup at home

• Annual professional development stipend
