About the Company: An established, profitable US-based B2B SaaS company behind a decade-old, revenue-carrying sales-engagement platform (cold email and outreach automation). Small, lean team. This is the most important engineering hire on the product. The Role: You will be a hands-on engineer who owns the platform day to day, end to end: backend services, frontend, AWS infrastructure, production debugging, and third-party integrations. Success in the first six months looks like this: you learn the stack fast, get it quiet by automating the manual work that still runs by hand, and then start building what's next. There is a clean handoff from the departing engineer, who will help you transition. What You'll Own: * Own the codebase end to end as the primary engineer: ship features, fix issues, keep production healthy * Get the stack quiet in your first weeks by automating the manual processes that still eat time today * Root-cause and resolve production incidents in live systems with paying customers: memory and heap issues, third-party API edge cases, queue backups * Run deploys and infrastructure changes as routine daily work across the AWS stack * Build and run your own AI agent workflows in Claude Code to multiply output across the repo * Take specced work, fill the gaps yourself, and deliver real estimates you can hit * Scope and build new products from scratch during heavier build cycles What We're Looking For: * 8+ years senior full-stack, comfortable being the primary engineer who owns the product end to end and makes the call * Senior TypeScript and Node, fluent across both modern frameworks and long-lived legacy codebases * Strong, current Angular, and genuinely energized to work in modern Angular. Someone still anchored to Angular 1.x who has no interest in the modern version is not a fit * Strong AWS operations as daily work: ECS Fargate, Lambda, SQS, Aurora (MySQL and Postgres), SES, CodePipeline and CodeBuild * Strong production debugging in systems with real paying customers * Deep daily use of AI coding tools: you work in Claude Code and have built your own agent workflows * You come from small or lean-team environments where you owned the whole thing, not big-company siloed teams * You build for the love of it and can show what you've built Nice to Have: * React * Email deliverability: DKIM, DMARC, SPF, warmup, blocklists, sender reputation * Mailbox-provider APIs: Gmail API, Microsoft Graph, IMAP and SMTP, OAuth * PHP and Laravel, Stripe or billing experience, Linux and Ansible, or a sales-tech / martech background * Public open-source work, your own agent or MCP tooling, or an active local dev community you can tap for part-time help Who You Are: You work well with a lot of autonomy: you find problems, fix them, and report back plainly. You have good product instincts, you think about customer impact, you treat billing code with care, and you would rather delete a dead feature than maintain it. You keep an eye on production because you care that it stays healthy. And you make AI tools a core part of how you work. Tools and Stack: TypeScript, Node, Angular, AWS (ECS Fargate, Lambda, SQS, Aurora MySQL and Postgres, SES, CodePipeline, CodeBuild), Claude Code. Details: * Location: Remote, Latam * Flexible PTO * Time Zone: Strong US business-hours overlap (Colombia is already US-aligned) * Salary: $60,000–$70,000/year USD * Type: Full-time
