Backend and data engineering will be your primary focus, but you’ll also make frontend changes in React, Next.js, and TypeScript to bring features through to completion.You should understand the complete flow of a production system:**Data ingestion → processing → storage → serving → API → frontend → production**For selected projects, you’ll own the full lifecycle: technical planning, implementation, deployment, product analytics, and iteration.What You’ll Own* Build and maintain Python backend services and production APIs.* Design, develop, and optimize ETL pipelines for large historical and geographic datasets.* Write advanced SQL and optimize BigQuery workloads.* Manage scheduled jobs, queues, background processes, and asynchronous workflows.* Operate GCP infrastructure, including Compute Engine, BigQuery, Cloud Storage, Pub/Sub, monitoring, and load balancing.* Improve how data is precomputed, packaged, cached, compressed, and served.* Debug issues across source data, pipelines, databases, APIs, infrastructure, and the user-facing application.* Improve system performance, reliability, scalability, and monitoring.* Make frontend changes in React, Next.js, and TypeScript, using AI coding tools to work efficiently.* Ship selected features end-to-end, measure adoption and performance, and iterate after launch.Must-Haves* Strong professional experience building Python backend systems and APIs in production.* Experience with BigQuery, advanced SQL, and large datasets.* Production experience with GCP, particularly Compute Engine, Cloud Storage, and Pub/Sub.* Experience building ETL pipelines, background jobs, and asynchronous processing.* Strong skills in data architecture, system design, performance optimization, and debugging.* Enough React, JavaScript, or TypeScript experience to contribute productively to an existing frontend codebase.* Daily use of AI coding tools such as Claude, Cursor, or GitHub Copilot.* Strong English communication skills for daily standups and one-on-one conversations with leadership.* Proficiency with Git and modern development workflows.* Availability for 40 hours per week aligned with U.S. Central Time business hours.Nice-to-Haves* Experience with PostHog or other product analytics tools.* Experience working with geographic or time-series data.* Experience with caching and data packaging for high-traffic applications.Who You AreYou’re a hands-on engineer who takes responsibility for how systems perform in production.

You don’t need to be a frontend specialist, but you should be comfortable completing the work required to deliver a usable feature.You care about what happens after launch: whether users adopt a feature, whether it performs reliably, and what should improve next. You communicate proactively, raise risks early, and recommend practical solutions.Who This Role Is Best Suited ForYour strongest experience should clearly be in **backend development, data engineering, and GCP**.This role is unlikely to be a fit if your background is primarily:* Data engineering without building APIs or backend services.* CRUD-focused backend development without substantial data processing experience.* Frontend development with limited backend and cloud experience.Working StyleYou’ll collaborate closely with leadership and the development team through daily standups, brief daily one-on-ones, and ongoing communication.Candidates based in LATAM are preferred, ideally in UTC-5 or UTC-6 time zones. Candidates elsewhere may be considered if they can fully commit to U.S. Central Time business hours.
