Shopify apps
that power thousands of online stores. We've developed

30,000+ Shopify merchants
worldwide, including over
1,000
Shopify Plus stores. In just a few years, our bootstrapped team grew from

in Annual Recurring Revenue (ARR) by obsessing over quality and merchant success. We're a tight-knit, 20-person team based in Baner, Pune, on a mission to help e-commerce brands create world-class shopping experiences.

Overview

We are looking to hire
two Full Stack Developers
who will drive the development of our merchant-facing web apps end-to-end. This is a
frontend-leaning full-stack role
– you will spend a majority of your time building and optimizing rich
React
dashboards and performance-heavy UI components, while also
designing and implementing backend APIs
and services in
Ruby on Rails
. You'll collaborate closely with product managers, designers, and fellow engineers to deliver new features from concept to deployment. This role offers the opportunity to influence product direction, tackle challenging scalability problems, and have a direct impact on the
30,000+ merchants
who use our apps.

Key Responsibilities

• Develop & Optimize Frontend UIs:
  Build sleek, responsive dashboards and merchant-facing interfaces using React, ensuring an exceptional user experience with a focus on performance and scalability.
• Backend API Development:
  Design, implement, and maintain robust backend services and RESTful APIs in Ruby on Rails to support new features and internal tools.
• End-to-End Performance Tuning:
  Optimize application performance across the stack – from minimizing frontend load times to improving backend query efficiency – for our high-traffic, data-intensive apps.
• Collaboration & Agile Delivery:
  Work closely with designers, product managers, and QA to translate requirements into technical solutions. Participate in sprint planning, code reviews, and daily deployments to ship features continuously and reliably.
• Quality & Maintenance:
  Write clean, maintainable code with appropriate test coverage (unit and integration tests) to ensure reliability. Monitor, debug, and resolve issues in production, and continually refactor and improve existing code for stability and performance.

What We're Looking For

• 3–4 Years Experience:
  Proven experience (3-4 years) as a software developer in a
  product company
  (experience in e-commerce or SaaS is highly preferred). You have built real products used by actual customers at scale.
• Front-End Excellence:
  Strong proficiency in
  React
  and modern frontend tooling (ES6+, webpack, etc.). You write clean, modular UI components and understand state management and performance tuning in the browser.
• Backend Proficiency:
  Comfortable building server-side applications and APIs with
  Ruby on Rails
  . You can implement business logic, integrate with databases, and create RESTful endpoints (bonus if you've worked with GraphQL or other backend frameworks).
• Dashboard & Tools Experience:
  Hands-on experience developing
  internal tools, admin dashboards, or merchant-facing apps
  is a plus – you understand how to build data-rich, intuitive interfaces for end users.
• Database & Cloud Knowledge:
  Familiarity with
  PostgreSQL
  (or other relational databases) – ability to design efficient queries and schemas. Exposure to
  AWS
  or similar cloud platforms for deploying and scaling applications.
• Product Mindset:
  You care about the
  why
  behind features. You are comfortable digging into requirements, questioning assumptions, and ensuring that we build solutions that truly solve merchant problems.
• Adaptability & Collaboration:
  Excellent problem-solving skills, communication, and ability to work in a fast-paced, collaborative environment. You are a self-starter who can take ownership of tasks and drive them to completion, but also know when to ask for help.

Tech Stack

• Frontend:
  React, TypeScript/JavaScript, HTML5, CSS3 (Tailwind/Bootstrap), modern build tools (Webpack, Babel).
• Backend:
  Ruby on Rails (REST APIs, background jobs), some services in Python.
• Database:
  PostgreSQL.
• Cloud & DevOps:
  Amazon Web Services (EC2, S3, RDS, CloudFront), Docker, CI/CD for daily deployments.
• Tools:
  Git (GitHub), Agile issue tracking (JIRA/Trello), and a keen use of automated testing.

(Don't worry if you aren't familiar with every item – we value willingness to learn. This is our current stack, and we continually adopt new technologies that improve our products.)

Why Join Us

• High Impact & Ownership:
  Your work will directly enhance the shopping experience of
  50M+ shoppers daily
  . At StarApps, developers deploy code daily and see the immediate impact on thousands of merchants – you'll own projects end-to-end and build features that matter.
• Fast-Growing, Profitable Startup:
  Join a
  bootstrapped, profitable
  company on an exciting growth trajectory (from $4M to $10M ARR). There's no bureaucracy here – just a passionate team
  obsessed with product quality and merchant happiness
  . You'll be part of our core team as we scale, with ample opportunities to grow into leadership roles.
• Cutting-Edge Tech & Challenges:
  Work with modern technologies (React, Rails, AWS) on
  performance-intensive applications
  . Tackle complex challenges in scaling, optimization, and UX for a global user base – continuously sharpen your skills in a supportive, learning-focused environment.
• Collaborative Culture:
  We are a small
  25-person team
  that operates like a close-knit family. You'll work side by side with experienced founders and a talented team that values innovation, humility, and continuous improvement. Our culture is open,
  empathetic
  , and growth-oriented – every voice is heard, and every team member plays a crucial role in our success.
• Growth & Benefits:
  We invest in our team's growth. Expect a competitive salary, performance bonuses, and whatever tools you need to do your best work. We sponsor professional development (courses, conferences, books) and encourage knowledge-sharing. You'll enjoy a flexible leave policy, team off-sites, and the excitement of building a global product from our new office in Baner, Pune.
