Software Development Engineer II, Full Stack - ReactJS & Java

Groupon is a marketplace where customers discover new experiences and services everyday and local businesses thrive. To date we have worked with over a million merchant partners worldwide, connecting over 16 million customers with deals across various categories. In a world often dominated by e-commerce giants, we stand out as one of the few platforms uniquely committed to helping local businesses succeed on a performance basis.

Groupon is on a radical journey to transform our business with relentless pursuit of results. Even with thousands of employees spread across multiple continents, we still maintain a culture that inspires innovation, rewards risk-taking and celebrates success. The impact here can be immediate due to our scale and the speed of our transformation. We're a "best of both worlds" kind of company. We're big enough to have the resources and scale, but small enough that a single person has a surprising amount of autonomy and can make a meaningful impact.

Deal Creation Tool Team

Who we are
The Deal Creation Tool (DCT) sits at the heart of Groupon’s Merchant Center, enabling merchants and internal sales teams to create, edit, and launch high-quality deals across Local, GLive, and future verticals. DCT’s unified flows, AI-assisted content, price intelligence, analytics, and autosave all run on a modern micro-service architecture (Ruby, React, Java, Postgres, Redis, Kubernetes, and AWS/GCP). We ship fast, measure everything, and celebrate impact—most recently cutting cloud cost 55 % while delivering features such as Multi-Voucher support and Buyer Min/Max controls.

Why this role matters
Our Q2’25 roadmap—AI-driven deal generation, multi-taxonomy relevance, auto-unpause, approval workflows, and an end-to-end deal-restructure—demands an engineer who can dive deep in the backend one moment and craft a polished React experience the next. As an SDE II you will own critical slices of that roadmap, influencing architecture, mentoring junior developers, and keeping reliability and performance front-of-mind.

What you’ll do

• Design & build full-stack features – from Ruby on Rails APIs and Java micro-services (Metro Draft, Deal Book, Cicero) to intuitive React/TypeScript UIs in Metro UI and MIA.

• Lead project work-streams – drive technical design docs, break down epics, surface risks, and deliver iterative value behind feature flags.

• Make AI useful – integrate LLM-powered “Inspire Me” copy generation and smart defaults, choosing the right prompt patterns, caching, and fallback strategies.

• Champion quality – write unit/contract tests, enforce CI gates, and embed observability (Grafana) so issues self-triage.

• Collaborate across functions – pair with Product, UX, Business teams to refine requirements, build merchant empathy, and ship the right thing.

• Mentor & learn – coach SDE Is, participate in design reviews, and absorb domain knowledge from senior architects—growing yourself while growing others.

We’re excited about you if you have

• 3-6 years of professional software development experience, with strong Ruby (or Rails) and one JVM language (Java) plus modern React/TypeScript.

• Solid understanding of relational databases (Postgres/MySQL), schema design, and query tuning; familiarity with Redis or Memcached for caching.

• Experience building, deploying, and operating micro-services in a public cloud (AWS, GCP, or Azure) using Docker/Kubernetes, CI/CD, and infrastructure as code.

• Comfort integrating or experimenting with AI/ML APIs or open-source LLM frameworks to enhance product functionality.

• Working knowledge of event streaming (Kafka/PubSub), REST/GraphQL APIs, and secure RBAC/authorization patterns.

• A bias toward measurable impact, clean code, and continuous improvement, backed by excellent communication and collaboration skills.

Nice-to-haves: Exposure to Salesforce integrations, image-management platforms (Bynder), or e-commerce/marketplace domains.

How we work

• Hybrid Bengaluru team with flexible core hours; we optimize overlap with EU/US teams and on-call rotations.

• Two-week sprints, architecture RFCs, strict CI, and data-driven decisions.

• Culture that prizes curiosity, psychological safety, and shipping value—not just writing code.

What’s in it for you

• Scope & ownership – own significant product surfaces used daily by merchants and internal teams worldwide.

• Learning & growth – clear career paths toward SDE III and beyond.

• Impact you can measure – each release moves key KPIs (deal adoption, GP30); we track and celebrate it.
