Job Description

About Juniper Square

Our mission is to unlock the full potential of private markets. Privately owned assets like commercial real estate, private equity, and venture capital make up half of our financial ecosystem yet remain inaccessible to most people. We are digitizing these markets, and as a result, bringing efficiency, transparency, and access to one of the most productive corners of our financial ecosystem. If you care about making the world a better place by making markets work better through technology – all while contributing as a member of a values-driven organization – we want to hear from you.

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

We’re looking for a Frontend Software Engineer to join our Platform team. The Platform team focuses on Foundational services (Identity and Access management, Authorization, Search, API Infrastructure), Frontend Foundations (design system, build configuration, infrastructure to build and consume NPM packages), and Developer Experience (GenAI tools, frameworks, and workflows to improve the entire software development lifecycle)

What you’ll do

Develop and maintain shared frontend libraries, build pipelines, component frameworks, and developer tooling.
Enhance workflows for frontend engineers, optimize CI/Deployment processes, and streamline local development.
Advocate for and implement modern frontend development patterns, accessibility standards, and performance optimizations.
Provide guidance, documentation, and support to product teams using the frontend platform.
Use observability tools to measure and enhance frontend application performance and reliability.
Work closely with product engineers and designers to align on platform improvements.

Qualifications

2–5 years of experience as a software engineer with a focus on frontend development.
Proficiency in JavaScript/TypeScript and experience with React, Vue, or other modern frontend frameworks.
Experience with module bundlers (e.g., Webpack, Vite, esbuild) and build tooling.
Familiarity with frontend performance optimization techniques and monitoring tools (e.g., Datadog RUM, Sentry, Lighthouse or similar).
Understanding of CI/CD and experience with tools like GitHub Actions, CircleCI, or similar.
Strong problem-solving skills and ability to work independently while collaborating effectively within a team.
Passion for improving developer experience through better tooling, automation, and documentation.
You must be flexible and adaptable—you will be operating in a fast-paced startup environment

Nice to Have

Experience working on a Platform team / building tools for other developers.
Experience contributing to design systems or shared component libraries.
Familiarity with micro frontends and frontend architecture patterns at scale.

Compensation

Compensation for this position includes a base salary, equity, and a variety of benefits. The U.S. base salary range for this role is $120,000 - $155,000 USD and the Canadian base salary range for this role is $98,000 - $122,000 CAD. Actual base salaries will be based on candidate-specific factors, including experience, skillset, and location, and local minimum pay requirements as applicable. Your recruiter can provide further details.

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

🎯 Who is this job for?

This role is best suited for a Middle Frontend Engineer (Software Engineer II) with 2–5 years of experience and strong skills in JavaScript/TypeScript and modern frameworks like React or Vue. It fits someone who enjoys building shared libraries, design systems, and developer tooling, and has hands-on experience with bundlers, CI/CD, and performance monitoring tools. You should be comfortable improving frontend architecture, optimizing developer experience, and collaborating across platform and product teams in a fast-paced environment.

💬 Potential Interview Questions

How would you design and maintain shared frontend libraries for multiple product teams?
I focus on clear APIs, strong TypeScript typing, backward compatibility, and semantic versioning. Documentation and examples are critical to ensure adoption and correct usage.
What are the key considerations when building and maintaining a design system?
Consistency, accessibility by default, performance, and ease of extensibility are essential. I also ensure strong collaboration with design and provide clear contribution guidelines.
How do modern bundlers like Webpack, Vite, or esbuild differ, and when would you choose each?
Webpack is highly configurable and mature, Vite offers fast dev builds via native ES modules, and esbuild focuses on speed and simplicity. Choice depends on project scale, customization needs, and build performance priorities.
How do you improve frontend developer experience in a growing organization?
I streamline local setup, reduce CI build times, automate repetitive tasks, provide templates and scaffolding tools, and maintain high-quality documentation.
How do you approach frontend performance optimization at scale?
I monitor real user metrics, reduce bundle size, apply code splitting, optimize rendering paths, and continuously measure Core Web Vitals to validate improvements.
How do you use observability tools like Datadog RUM or Sentry in frontend applications?
I track runtime errors, performance metrics, and user flows to identify bottlenecks, regressions, and reliability issues, then prioritize fixes based on impact.
What role does CI/CD play in frontend platform engineering?
CI/CD ensures consistent builds, automated testing, and safe deployments. I optimize pipelines to reduce feedback loops and maintain high confidence in releases.
How do you advocate for modern frontend patterns across multiple teams?
I lead by example through shared libraries, RFCs, and documentation, and support teams with guidance and migration paths rather than enforcing abrupt changes.
What architectural patterns do you consider for scaling frontend applications (e.g., micro frontends)?
I evaluate modular monoliths first, then consider micro frontends when team autonomy and independent deployment become critical, balancing complexity with real needs.
How do you collaborate with product engineers while working on a platform team?
I treat them as internal customers, gather feedback regularly, prioritize improvements based on impact, and ensure platform changes directly support product delivery speed and quality.
