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 the Role
We’re looking for a Principal Engineer to join our Platform team, which owns foundational services like CIAM, Authorization, Search, API Infrastructure — and the tools, frameworks, and developer experience improvements that power engineering at Juniper Square. You’ll be the senior-most technical voice on the team, blending hands-on engineering with technical leadership, architectural ownership, and cross-functional influence.
What You’ll Do
Operates as the Directly Responsible Individual (DRI) for high-impact initiatives; takes full ownership of project health, system design, and end-to-end delivery.
Partners closely with Product Management and cross-functional teams to clarify ambiguous requirements, map business goals to technical scopes, and manage dependencies.
architectural design, pragmatic task breakdown, and execution planning, driving a team of engineers toward incremental deliverables.
Establish reusable patterns, technical standards, and platform primitives that other teams can build on.
Improve engineering efficiency through better tooling, automation, documentation, observability, and developer workflows.
Mentor engineers, raise the quality of technical decision-making, and help the team execute with consistency.
Drives adoption of AI tooling across the SDLC — building internal capabilities that automate engineering workflows while ensuring security, compliance, and best-practice alignment.
What We’re Looking For
12+ years of experience designing, building, and operating large-scale distributed production systems.
Strong backend engineering experience with Python frameworks such as FastAPI, Flask, Pyramid, or Django.
Experience leading technical design for complex systems, including making architecture decisions, evaluating tradeoffs, and guiding implementation across multiple engineers or teams.
Experience with relational/nosql databases, including schema design, performance tuning, query optimization, and data modeling.
Experience building and operating cloud-native systems using technologies such as AWS, GCP, Azure, Docker, Kubernetes, and infrastructure as code.
Strong understanding of CI/CD, observability, reliability, and operational excellence in production environments.
Ability to work through ambiguity, break down complex technical problems, and drive alignment across engineering, product, and design.
Strong ownership mindset, with the ability to independently drive high-impact initiatives while collaborating effectively in a fast-paced environment.
Demonstrated ability to raise engineering quality through technical standards, design reviews, mentoring, and reusable platform patterns.
Passion for improving developer experience through better platforms, tooling, automation, documentation, and engineering workflows.
You are flexible and adaptable—you will be juggling multiple projects in a fast-paced startup environment.
Comfortable driving a technical vision with a focus on shipping value incrementally rather than waiting for a big-bang release.
Nice to Have
Platform team experience building tools and services consumed by other developers.
Experience building or integrating AI/LLM-powered systems in production, such as AI SDKs, RAG pipelines, evaluation frameworks, guardrails, prompt/tool orchestration, or model observability.
CIAM/Identity systems — Auth0, Okta, OAuth 2.0, OIDC, SAML, or custom-built identity infrastructure.
Security-aware design — least-privilege access, secrets management, secure API gateway patterns.
Passion for growing others through coaching, delegation, and leading by example.
