[Hiring] Software Engineer @UserGems

Role Description

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 looking for a Senior Full-Stack Engineer who combines strong engineering fundamentals with a practical mindset. You’ll join our web application team with a 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.

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 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.
• Are used to strongly leverage AI in your day-to-day development workflow.

What You’ll Do:

• Build user-facing UIs in collaboration with a product manager and your teammates.
• Build scalable data-heavy background processing jobs handling terabytes of data.
• Build new features with both humans and AI agents in mind (MCP).
• Integrate and maintain connections with external data providers, ensuring data reliability, consistency, and quality across ingestion pipelines.
• Participate in architectural discussions and make sound trade-off decisions.
• Design, build, and optimize relational database structures (MySQL).
• Collaborate closely with data scientists to optimize AI workflows and prompts.
• Debug, profile, and tune systems for reliability and performance at scale.
• Write clean, maintainable, and testable code with an eye for long-term stability.
• Continuously improve workflows, deployment, and monitoring practices.

Qualifications

• 4+ years of experience as a PHP developer (preferably with Laravel).
• 2+ years of experience as a frontend or full stack developer (TypeScript).
• You take ownership of outcomes, not just tasks.
• You bring full-time focus and accountability - we’re a small team, and everyone’s contribution matters.
• You’re reliable, consistent, and communicate openly when priorities or availability change.
• Expertise in relational database modeling, query optimization, and high-performance tuning.
• Experience working in a startup or fast-moving environment.
• Ability to work independently and self-organize.
• Fluent in English, both written and spoken (preferably with prior work experience with English as the main working language).
• Curious mindset and willingness to explore unfamiliar systems.
• Pragmatic: you balance technical purity with delivery speed.

Benefits

• Impact and ownership: You’ll ship code that directly affects revenue and product direction.
• Modern tech stack, strong peers: Work alongside experienced engineers in a team that values autonomy and quality.
• Remote-first across Europe and Brazil: Flexible work setup and async-friendly culture.
• High trust culture.
• Competitive compensation and growth opportunities.
