About the role

View original

GRIN is seeking a Senior Software Engineer to help drive the continued evolution of our core platform, GRIN Classic. The foundation of the leading influencer marketing software trusted by top global brands. This is a rare opportunity to work end-to-end on a live, revenue-generating SaaS product where every improvement directly impacts customers.

You’ll work in a lean, high-autonomy environment—owning projects from ideation through deployment without layers of management or bureaucracy slowing you down. You’ll collaborate closely with customer-facing teams to identify, prioritize, and deliver meaningful product and infrastructure enhancements that make GRIN faster, more stable, and more scalable.

As our next-generation platform (Gia) matures, you’ll also gain exposure to AI-driven engineering through close collaboration with our advanced AI engineering team—an opportunity to evolve your skill set and influence the next phase of GRIN’s technical transformation.

What You’ll Do

  • • Design, build, and maintain features and services that solve real customer problems and scale efficiently.

  • • Lead and execute projects end-to-end—requirements, implementation, testing, deployment, and monitoring.

  • • Collaborate directly with internal teams and customers to understand needs and craft practical, reliable solutions.

  • • Continuously improve system performance, reliability, and maintainability through thoughtful engineering.

  • • Engage in architectural discussions and influence long-term technical direction.

  • • Mentor peers and contribute to a culture of technical excellence and shared learning.

  • Why You’ll Love This Role

  • • High Autonomy: No management layers. You own your projects and see them through to production.

  • • Visible Impact: You’ll work on a live system used by real customers every day—your code matters immediately.

  • • Fast Cycle Times: Small, focused projects ship quickly—no six-month marathons.

  • • Full-Stack Variety: Work across front-end, back-end, infrastructure, and data layers for continuous skill growth.

  • • AI Exposure: As GRIN transitions toward our AI-native platform, you’ll gain firsthand experience working alongside seasoned AI engineers (expected over the next 12 months).

What We’re Looking For

  • • 5+ years of professional software development experience in production environments.

  • • Strong proficiency in JavaScript with experience in modern frameworks (Vue.js, React, or Angular).

  • • Back-end experience with PHP (Laravel preferred), Go, or similar.

  • • Solid database fundamentals (SQL, MySQL, or PostgreSQL; MongoDB a plus).

  • • Experience working with AWS or other cloud platforms.

  • • Familiarity with Git and collaborative development workflows.

  • • Clear communication skills and a collaborative, self-directed working style.

  • • Comfort using Cursor or similar AI-assisted coding tools.

  • Required Qualifications:

  • • 5+ years of software development experience in production environments.

  • • Proficient in JavaScript and experienced with modern front-end frameworks such as Vue.js, React, or Angular.

  • • Back-end experience in PHP (Laravel preferred), Go, or similar.

  • • Strong understanding of database design and development (SQL, MySQL, PostgreSQL; MongoDB a plus).

  • • Familiarity with version control systems (Git) and team-based development workflows.

  • • Clear, effective communication and collaboration skills.

  • • Familiarity with AWS or equivalent cloud infrastructure.

  • • Comfort using Cursor to write and troubleshoot code.

  • Bonus Skills

  • • Experience building or maintaining distributed systems or event-driven architectures.

  • • Proficiency designing and optimizing APIs and data flows.

  • • Familiarity with observability tools (Datadog, Sentry, etc.) and performance profiling.

  • • Experience identifying and solving scalability or data-processing bottlenecks.

  • Additional Benefits:

  • • Wellbeing Allowance: $120/month

  • • Learning and Development Allowance: $30/month

  • • Stock Options/Equity
