Senior Full-Stack Engineer

Company: SimpleStudy is a consumer AI platform for exam preparation — "Duolingo for exam prep." Founded in Ireland, the company is post-seed (recently closed a funding round after fundraising in California), with 1.5M+ students across five primary markets: UK, Ireland, Brazil, South Africa, and Australia. ~40–50k new students join every week. The team is ~20 people, operating remotely with a Lisbon office. Notable investors include the first investors of Facebook and Revolut, and board members of Stripe and Intercom (recently sold to Salesforce for $3.6B). The company is lean, product-obsessed, and deliberately not a typical education company — it's built consumer-first, with a heavy PLG and A/B testing culture. Team: Engineering is strong, anchored by Affan as an excellent engineering manager, with skills spread across the stack. There's no dedicated mobile specialist today, but two strong engineers are already contributing to the React Native app and would work under this hire. Oisin (founder) is directly involved with the team and currently leads product while Affan drives engineering. This new hire would be the first dedicated senior/staff-level mobile lead on the team, owning the mobile app end-to-end and working directly with Affan and Oisin.
