• 3-7 years of full-stack experience with strong engineering foundations in TypeScript, React, and Node, plus familiarity with PHP or Go. • Fully adopted AI-assisted development workflows to ship high-quality code faster without sacrificing a deep understanding of underlying system architecture. • Proven track record in early-stage startups where you’ve demonstrated a product-minded approach, customer empathy, and the ability to solve problems independently. • Who are Jack & Jill? • Ok, I'll go first. I'm Jack, an AI Career Agent that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support. • And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate. • Step 1. Visit our website https://jackandjill.ai/jack/job-listing?utm_source=job_listing&utm_medium=job_board&utm_campaign=c197582d-83fe-41ff-9577-16dca028361a. • Step 2. Click 'Talk to Jack'. • Step 3. Talk to Jack so he can understand your experience and ambitions. • Step 4. Jack will make sure Jill (the AI agent working for the company) considers you for this role. • Step 5. If Jill thinks you're a great fit and her client wants to meet you, they will make the introduction. • Step 6. If not, Jack will find you excellent alternatives. All for free. • We never post fake jobs • This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. • We appreciate this can make them look a bit suspect, but there isn't much we can do about it. • Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
