Senior Full-Stack Engineer (TypeScript, Angular, AWS)

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.

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 .
