The Lowdown:

Wolf is the platform behind the next generation of staffing companies. We help firms launch their own talent marketplaces — complete with jobseeker apps, client portals, and internal recruiter tools — all white-labeled and powered by Wolf’s engine.

We’re looking for a Senior Ruby on Rails Engineer to join us remotely and help build the backbone of modern flexible work. You’ll be working on everything from scheduling and payments to multi-tenant logic, API design, and internal tooling.

This role is perfect for someone who’s comfortable in a startup — fast-moving, pragmatic, product-minded — and excited to bring technical excellence to real-world features that impact thousands of workers and help us scale.

Your Impact:

• Contribute to backend development, in both serverful and serverless infrastructure. Bonus points for domain-driven design experience!
• Enhance system design for scalability, reliability, usability, and performance.
• Bring your point of view and experience to work across the company, so we all improve and win together.
• Write and maintain high-quality, scalable Ruby code.
• Design and build robust, scalable APIs using AWS API Gateway.
• Build integrations with third-party applications and services, as well as the platforms and services that will power them.
• Improve system observability, monitoring, and alerting.
• Troubleshoot, identify, and resolve performance bottlenecks and bugs.
• Collaborate with front-end engineers to ensure seamless API integration (Vue or React experience is a plus).
• Drive best practices in code quality, testing, and DevOps.

What’s In It for You?

• A role where you can make an immediate impact for real people who run their business on your code.
• You’ll work with sharp, low-ego people who move fast and laugh often.
• Competitive salary + performance-based bonuses.
• A fast-paced environment where your ideas matter.
• The opportunity to grow with a high-potential, venture-backed startup.

What You Bring:

• Expertise in Ruby (minimum 3 years) on production applications, and ideally with PostgreSQL, Redis, Sidekiq, and RSpec as well.
• Some AWS experience, ideally including with serverless architecture (Lambda, DynamoDB, API Gateway, RDS, S3, Beanstalk).
• Experience working with product and design teams to solve problems. Even better if you’ve worked directly with customers also!
• Proficiency with Git, GitHub, and modern CI/CD pipelines.
• Strong problem-solving skills and the ability to work independently in a fast-paced environment.
• Bonus: Experience with front-end frameworks like Vue or React.
