About the Role
We're looking for a Principal Engineer to join 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.
