Senior Backend Engineer, Java

• We're hiring senior backend developers with deep Java experience!

If you have a stable hand with backend Java, we'd be very interested in talking to you.

Makers' Den is a remote-first software studio run by developers, for developers.

We build modern web & mobile apps and do software modernizations for global clients. Previously we’ve had a heavy React/Typescript focus but now we're growing our backend muscle with senior Java Makers.

If you're the kind of person who takes pride in clean, maintainable code and enjoys having real ownership over what you ship, you'll fit right in.

• What you'll do
• Design, build, and maintain backend services in modern Java (17+), with room to shape its architecture. Kotlin knowledge is a plus.
• Make the calls that seniors make: API design, data modeling, concurrency, performance, and the trade-offs in between.
• Collaborate directly with clients and teammates - from feature discussions to deployment.
• Review PRs, give feedback, and help keep codebase elegant and reliable.
• Contribute ideas: we value people who think beyond the ticket.
• What we value
• Solid experience (8+ years) with backend Java, and fluency with the modern JVM ecosystem (Spring Boot or similar, build tooling, testing).
• Real depth where it counts: concurrency, correctness under load, and API design that other teams enjoy consuming.
• Pragmatism - you know when a design pattern earns its keep and when it's ceremony.
• Comfort working independently and asynchronously in a remote setup.
• Consistently reporting on progress via PRs, demos via recorded screenshare videos and up-to-date project boards.
• Ability to use AI/LLMs as a force multiplier in delivering your work.
• Optional, but welcome: interest in occasionally crossing into TypeScript/React work.
• Curiosity, humility, and kindness. We like people who make the team better.
• Why Makers' Den
• 100% remote - no offices, no micromanagement.
• Founders are active senior devs - we code, review, and mentor (when we have time ).
• Annual in-person meet-up (company-paid travel, hotel, and dinners).
• A culture of autonomy, craft, and learning - no unnecessary managerial layers.
• The process
• Short intro call.
• Small take-home coding challenge (reasonable and realistic).
• 90-minute conversation - we'll discuss your work and ours.
• Offer, if we're a match.
• Learn more about us in our Maker Handbook .

We look forward to hearing from you!
