L3 Support Engineer (Python)

Summary

At Remote Crew, we're partnering with a VC-backed AI sales platform looking for an L3 Support Engineer. You'll debug complex production and customer issues across Python services, APIs, integrations, and data pipelines, then fix what's in scope or escalate with clear findings. You'll join a close-knit team of 4 with direct visibility to leadership.

• Salary: $30k/year - $35k/year (B2B)
• Location: Remote, based in Argentina, Brazil or Colombia. Fully remote.

What You'll Do

• Own complex customer escalations end to end. Reproduce the issue, investigate, find root cause, fix or escalate, test, document.
• Debug Python services, APIs, background jobs, data pipelines, and databases.
• Analyze logs, metrics, and customer data to tell apart configuration issues, data problems, integration failures, and product bugs.
• Investigate reliability and performance issues. Slow requests, async problems, resource exhaustion, intermittent failures.
• Implement production-quality fixes when the issue is within your scope, backed by tests.
• Improve API and integration reliability through validation, retries, and error handling.
• Monitor production systems using Sentry and Datadog. Catch issues before they spread.
• Support releases through post-deployment checks and regression detection.
• Escalate larger issues to Engineering with clear reproduction steps and evidence.
• Write RCAs, runbooks, and troubleshooting guides for the team.
• Join customer calls occasionally to explain technical issues and resolutions.

What We're Looking For

• You have strong debugging skills across application code, APIs, databases, and production environments. This is your core daily work, not a side task.
• You communicate concisely and precisely. No long explanations, just the facts that matter.
• You know Python for backend work, or React for frontend work. You don't need both.
• You're comfortable querying databases and comparing data across systems to find where a failure starts.
• You understand HTTP/REST, authentication, retries, timeouts, and common integration failure modes.
• You're based in Argentina, Brazil, or Colombia, and work in the same time zone as the team.

Nice to Have

• Experience with Flask, FastAPI, MongoDB, or PostgreSQL.
• Experience with Celery, Redis, or other background job systems.
• Exposure to AI products or AI tooling.
• Experience with Salesforce, Outlook, Slack, or other SaaS integrations.
• Familiarity with Sentry, Datadog, Zendesk, or Jira.

Why Work With Us

• You'll work on an AI-driven platform backed by top VCs, founded by repeat entrepreneurs from Google, Yahoo, and VMware.
• This is a hands-on role. You implement real fixes, not just triage tickets.
• Work is assigned dynamically across tickets, logs, and ad hoc requests. You'll learn across the whole stack, not just one corner of it.
• The current team lead is being promoted internally. That's the kind of growth path this team offers.
• You're one of 4 people on the team, with direct visibility to the company's leadership.

If you like solving hard problems and explaining them clearly, we'd love to hear from you.
