Jobbeschreibung

Headquarters: Remote @ Colombia

About the role:

The the company Connect team builds the moments that turn a listing into a sale. Every chat between buyers and sellers, every offer notification, and every saved-search alert runs through services we own, from messaging and notifications to location, meetups, and the subscriptions sellers pay for. We run high-volume Java microservices and streaming pipelines, integrate with partners like Braze, Amazon Pinpoint, Apple, and Google, and use experimentation to decide what ships.

We also take on high-visibility work beyond our domain. Connect built the company's video infrastructure for listing videos and LLM-powered catalog enrichment on Amazon Bedrock, both company priorities that changed what buyers see every day. The roadmap is wide open for someone who wants to help shape it.

As a Software Development Engineer II, you'll own features from concept to rollout: designing and writing well-tested code, launching experiments, and measuring results with Product, Design, and Data partners. You'll raise the quality of the code around you and get the chance to join the next project like video or catalog enrichment.

Here’s more of what you will get to do:

Design, build, and deploy backend services and event-driven pipelines for messaging, notifications, location, and subscriptionsImprove the reliability, latency, and delivery rates of high-volume messaging and notification systems, including retries, rate limiting, and frequency cappingIntegrate with and operate third‑party platforms such as Braze, Amazon Pinpoint, Apple and Google push services, and app store billingOwn features end‑to‑end: plan, design, develop, deploy, measure, and iterateBreak down complex engineering problems into achievable tasks and deliver them within committed timeframesWork collaboratively with cross‑functional teams (Product, Design, Data Science, Marketing, and iOS, Android, and web engineers) to design and implement new featuresContribute to A/B tests and use experimentation results to decide what shipsActively participate in code reviews and enforce good patterns, testing, and edge‑case handlingCoach and mentor junior team members, new hires, and internsCreate shared components, utilities, and services that improve team velocity across the stackMaintain and improve the runbooks, alerting, and monitoring for the features you shipParticipate in a reasonable on‑call rotation with the rest of the teamUse AI coding tools (Claude Code, Gemini, and similar) to increase your daily development velocity and code qualityBecome a subject matter expert in one or more of the team's sub‑domains: messaging, notifications and campaigns, location, or subscriptions and promotionsYou’ll thrive in this role if you have:
