THE ROLE
In today's cloud-centric world, the reliability of cloud platforms underpins everything. Ensuring the heartbeat of these systems is crucial. At the frontier of cloud technology, Site Reliability Engineering (SRE) works diligently to bolster the availability of our cloud infrastructure and services.

WHAT YOU BRING
- Strong experience designing, operating, and improving highly available cloud services, including deep understanding of service uptime, SLOs, and production operational excellence.
- Expertise with public cloud platforms (AWS, Azure, or GCP) and hands-on experience with cloud-native architectures.
- Proficiency in Infrastructure-as-Code and automation using tools such as Terraform, Ansible, CloudFormation, Puppet, or similar.
- Practical experience running containerized environments and orchestration systems such as Kubernetes.
- Ability to build and operate observability stacks (e.g., ELK, Prometheus, OpenTelemetry) and manage on-call processes using tools like PagerDuty.
- Strong programming skills in languages such as Python, Go, Java, Ruby, or similar.
- Deep understanding of Linux systems, networking fundamentals, and modern software delivery practices.

Senior Full-Stack Engineer — CoreApps Platform (AI-native, Encore)
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.
About the Role
Senior Full-Stack Engineer — CoreApps Platform (AI-native, Encore)
A builder role on the team that powers Groupon's global commerce engine.
CoreApps Platform is the foundational engineering group powering Groupon's global commerce engine — every customer interaction and every transaction, worldwide. This is a builder role: you take features from problem statement to production across backend, frontend, CI/CD, and test automation, using Claude Code as your daily leverage tool. You own the whole slice. You unblock yourself. You ship.
What You'll Do
- Drive features end-to-end. Backend services, frontend surfaces, CI/CD pipelines, test coverage, deploy, monitor — the whole vertical slice. No handoffs, no "that's someone else's team."
- Ship on legacy and cutting-edge together. Modernize Java / Ruby systems into TypeScript / Node.js on Encore, while keeping services at 100K+ RPM running cleanly.
- Operate Claude Code natively. Daily agentic workflow with MCPs, skills, hooks, evaluation patterns — AI is not a productivity add-on, it's how you collapse FE + BE + DevOps + QA into a single-engineer scope.
- Cut through red tape. Find the path. Kill process that doesn't protect anything. Respect process that does. Escalate when you can't, ship when you can.
- Lift your peers. Share patterns, unblock teammates, leave the codebase cleaner than you found it.
Must Have
- 5+ years shipping production software, with deep production TypeScript / Node.js as your primary backend stack (NestJS / Fastify / Encore or similar, named and used).
- Full-stack range. You've owned features across backend and frontend, and you're comfortable in CI/CD pipelines, test automation, and production debugging. Specialist-only profiles (backend-only, frontend-only) will not fit this role.
- Claude Code native. Daily use with a demonstrable personal setup — MCPs, skills / agents, hooks, or equivalent automation. You can screen-share it. Autocomplete-only and Cursor-only do not qualify.
- Builder bias. Evidence of projects you drove beginning to end — scoped the problem, designed the approach, shipped it, operated it. No "I contributed to…" answers — we want what you built.
- Distributed systems fundamentals — API design, SLOs, structured observability, on-call ownership.
- High-bandwidth communication — written and verbal, across technical and non-technical audiences.
Nice to Have
- Java or Ruby reading fluency (for navigating the source systems being migrated).
- E-commerce / marketplace scale experience.
- Encore, Temporal, or similar workflow frameworks.
- Frontend frameworks used in anger (React, Next.js).
What Success Looks Like
First 30 days: operating in the team's AI workflow on day one — Claude Code setup running, first PR merged, owning a service.
First 90 days: shipped at least one end-to-end feature across the full stack, reduced a real bottleneck, demonstrably faster velocity than traditional backend-IC pace.
First 180 days: the team points to work only you could have driven at that pace — migration cutovers, FE + BE features shipped as single units, tooling peers now depend on.
We Are Interested In
Builders. Engineers who take scope from "this is a problem" to "this is in production" without waiting for permission. Fluent in Claude Code as the force multiplier that makes one engineer effective across backend, frontend, DevOps, and QA. Deep in TypeScript, comfortable anywhere in the stack, energized by cutting through noise and shipping. If you wait to be told what to do, this role will frustrate you.

About the Role
Engineering Manager – Marketing Platform (Dispatch & Subscriptions)
Groupon's Marketing Engineering team owns the systems that connect millions of users with the right offer at the right time. This includes our Dispatch platform (real-time communications infrastructure) and Subscription systems that drive engagement and conversion at scale.
As Engineering Manager, you'll lead distributed engineering teams responsible for the reliability, scalability, and evolution of these platforms. You'll be accountable for both keeping the lights on and driving meaningful modernization — reducing operational costs, shipping AI-enabled features, and building a team that executes with ownership and speed.
This role sits at the intersection of platform engineering and business impact. If you're energized by large-scale distributed systems, cross-functional delivery, and growing engineers — this is for you.
Key Responsibilities
-
Own end-to-end delivery across Dispatch and Subscription platform services, ensuring 99.99% uptime and sub-1s latency for real-time communications
-
Lead and grow a distributed engineering team; manage performance, run regular 1:1s, and build a strong culture of ownership and accountability
-
Drive platform modernization: reduce technical debt, optimize cloud resource usage, and target a 30% reduction in operational costs over 12 months
-
Partner with product, data, and marketing stakeholders to align engineering delivery with business priorities
-
Set and enforce engineering standards — code quality, CI/CD pipelines, microservices patterns, and incident response
-
Participate actively in architectural decisions, design reviews, and technical direction within your team's scope
-
Champion AI/ML integration where it delivers measurable outcomes — intelligent routing, automation, personalization; target at least 2 AI-driven features shipped per year
-
Own hiring across your team: sourcing, interviewing, onboarding, and ongoing development
Key Requirements
-
Hands-on software engineering and leadership experience
-
Hands-on background in Java and distributed systems; comfortable reviewing architecture and code when needed
-
Proven experience managing platform or communications infrastructure at scale in a microservices, cloud-native environment
-
Strong AI-First approach and working knowledge of AWS or GCP; familiarity with Kubernetes, Terraform, and messaging systems (Kafka, RabbitMQ)
-
Experience leading geographically distributed teams across time zones
-
Demonstrated ability to manage ambiguity, balance competing priorities, and deliver in fast-moving environments
-
Track record of performance management, career development, and team building
Nice to Have
-
Familiarity with Ruby, Node.js, or React in addition to Java
-
Experience with email/push/SMS communication platforms or subscription management systems
-
Exposure to AI/ML integration in production systems
-
Background in marketing technology or customer engagement platforms
What Success Looks Like
-
30 days: You understand the platforms, team dynamics, key stakeholders, and top 3 risks. You've had 1:1s with every direct report and flagged immediate delivery blockers.
-
60 days: You've taken ownership of sprint planning, are running team rituals effectively, and have a clear view of the technical debt backlog with a prioritization proposal.
-
90 days: You've shipped at least one meaningful improvement, established clear performance baselines, and have a 12-month roadmap draft aligned with business goals.
We Are Interested In
-
Leaders who make decisions anchored in customer and business outcomes
-
Managers who build autonomy in their teams rather than creating dependency on themselves
-
Engineers who treat AI as a tool, not a trend
-
People who can hold quality standards in a messy, fast-moving environment without slowing everything down
-
Communicators who can translate complexity for non-technical stakeholders without dumbing it down
