Senior Full-Stack Engineer

About the role

We're hiring a senior full-stack engineer who can own customer-facing problems end-to-end. Reports to: Head of Engineering.

What’s driving this hire

We need the kind of person who treats a confusing production issue not as a ticket to grind through, but as a problem to chase down and fix at the root. We need someone whose instinct is to find these issues before they cost us, and who's energized by untangling cross-system mysteries.

What you’ll do

• Own customer-impacting issues end-to-end.
• Debug across the stack: Rails, database, third-party integrations, iOS app.
• Fix the root cause, ship it, and follow up with our client success team or with the customer directly.
• Build and maintain our integrations.
• Ship new functionality across the backend and web dashboard.
• Work directly with customers when it helps.
• Maintain quality standards.

Who we’re looking for

• 5+ years building and operating production web applications, with strong full-stack range and real depth on the backend.
• Strong Ruby on Rails experience (or deep experience in a comparable framework plus enthusiasm to go deep on Rails quickly).
• Excellent systems-debugging instincts.
• Real integration experience: REST APIs, webhooks, OAuth, and the patience to work with flaky or poorly documented third-party systems.
• B2B SaaS that integrates with many vendors is ideal.
• Comfortable working with relational databases (we use Aurora MySQL).
• Writing and optimizing queries, reasoning about data integrity and sync.
• A customer-facing temperament. Willing and able to get on a call with a customer's technical staff, communicate clearly in writing, and represent engineering with professionalism.
• Operationally mature. You've shipped hotfixes, and you understand that owning software means owning what happens after it ships.
• Thrives with autonomy on a small, senior team. You turn ambiguous problems into plans without much hand-holding.

Nice to have

• Exposure to the realities of small-team product engineering.
• Familiarity with GraphQL.
• Experience troubleshooting unconventional hardware issues in real-world, production environments.
• Experience developing iOS/iPadOS apps in Swift.
• Hospitality, operations, or point-of-sale integration experience.
• Experience with telephony/SMS platforms (Twilio) and their international compliance quirks.

What this role is not

This is not a heads-down, ticket-queue role where well-specified work arrives and you implement it in isolation. You'll own ambiguous, customer-facing problems and see them all the way through, support included.

What it’s like to work on our engineering team

• You’ll share real ownership of meaningful systems.
• Your ideas will help shape the product and technical direction.
• The engineering team has had zero departures in five years.
• You’ll regularly participate in pair/mob programming sessions with teammates.
• We encourage thoughtful experimentation with new tools and technologies that can improve performance, reliability, or developer happiness.
• You’ll work closely with product, design, and customer-facing teams.
• We value pragmatic engineering over over-engineering.

What it’s like to work at Chexology

• Medical, dental, and vision insurance with a $400 monthly employer contribution.
• 401(k) plan to support your long-term financial goals.
• Flexible PTO policy, plus holiday office closures, to recharge.
• Company-provided laptop and tools to help you do your best work.
• Enjoy virtual game days, seasonal get-togethers, and company gatherings that bring the team together to connect, unwind, and celebrate wins.
