Senior Full-Stack Software Engineer (php/laravel, typescript/vue)Build scalable systems that power AI-driven sales intelligence
UserGems is an AI platform helping sales and marketing teams double their pipeline impact with the same resources. Our AI agent, Gem-E, identifies who to target, when, and why - turning signals from CRMs, buying intent, and public data into precise and timely outreach that drives revenue.
We’re building an AI-powered signal platform that automates repetitive sales and marketing tasks and connects insights across all customer-facing systems.
The Role
We’re looking for a Senior Full-Stack Engineer who combines strong engineering fundamentals with a practical mindset. You’ll join our web application team with heavy backend processing job focus. Your work will also involve frontend work to build the customer facing UI, but is typically backend (php/laravel) dominant.
UserGems is a ~60-person company with around half of them working in engineering in Europe and Brazil and the other half in sales and marketing based in the U.S. You’ll be part of a technically strong, fast-moving engineering group that collaborates closely with our go-to-market teams in the U.S.
We’re in a phase where speed and iteration matter most - we move fast, ship often, and improve continuously.
You’ll join one of our 3 webapp teams and take ownership of entire components within the first few months of starting at UserGems. The role offers a high degree of autonomy within a collaborative, high-trust environment. You’ll work closely with teammates across Europe and Brazil and frequently with our marketing and sales teams in the U.S., so you should be comfortable working in English and collaborating asynchronously across time zones.
You’ll thrive in this role if you:
- Work comfortably with a high degree of independence and ownership.
- Learn quickly and stay effective in a changing environment.
- Approach complex technical problems with practical, solution-oriented thinking.
- Value working in a dynamic company where impact matters more than process.
