Software Engineer II (Fullstack) - India

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.

• Participate in code reviews

• Participate in architecture discussions and collaborate cross-functionally

• Ensure high availability and reliability of APIs

Qualifications

• 4-6 years of experience in full-stack software development.

• Proven experience building and scaling public-facing APIs

• Strong understanding of REST principles, API versioning, and backward compatibility

• Experience with asynchronous task processing using Celery

• Solid experience with PostgreSQL (query optimisation, indexing, transactions)

• Strong understanding of database design and performance tuning

• Experience with caching mechanisms such as Redis

• Experience deploying and operating services on AWS (EC2, RDS, S3, Lambda, ECS/EKS preferred)

• Experience with API Gateway, rate limiting, and web application firewalls (WAF)

• Strong understanding of authentication and authorisation (OAuth2, JWT)
