Full-time

Paystone

Join the Paystone team and build technology that makes an impact!

At Paystone, we’re all about bringing together talented people who love solving problems, challenging the status quo, and creating solutions that make a difference for our clients. ✨

We’re looking for a Hotfix (Technical Service) Developer who is curious, analytical, and ready to jump into complex technical challenges. If you enjoy digging into problems, figuring out what is happening behind the scenes, and turning challenges into reliable solutions, we’d love to have you on our team.

Ready for your next challenge? Let’s build something great together.

Overview
The Hotfix team is responsible for delivering urgent, high-impact fixes for enterprise clients. This role requires strong problem-solving skills, attention to detail, and the ability to work under time-sensitive conditions. The Hotfix Developer ensures client issues are investigated, resolved, and deployed quickly while maintaining data integrity and minimizing risk.

Key Responsibilities
  • Investigate and resolve urgent production issues raised by Success, Support, Project or Account Management.
  • Write and execute SQL queries for data corrections, imports, exports, and reporting fixes.
  • Perform root-cause analysis on transactional data, logs, and system behaviors.
  • Read and understand the PHP/Symfony codebase to troubleshoot issues and confirm system logic.
  • Build and run custom scripts (PHP, SQL) for bulk updates, data migrations, or exports.
  • Deploy fixes safely using internal tools (Phing, etc.) with rollback plans if necessary.
  • Collaborate with cross-functional teams (Support, Success, Account Management, Core, etc.) to clarify requirements and validate solutions.
  • Document fixes thoroughly in Jira, including logic, risks, and testing steps.
  • Participate in Hotfix sprint planning, standups, and reviews.
  • Assist in maintaining and improving Hotfix workflows, documentation, and best practices.
  • Provide proactive communication on ticket progress, risks, and blockers.

Required Skills & Experience

  • 2–4 years of experience in software development, technical support engineering, or a developer-facing technical role.
  • Strong SQL skills (queries, updates, imports/exports, data validation).
  • Solid understanding of debugging and troubleshooting transactional or log-based systems.
  • Proficiency in PHP and familiarity with the Symfony framework.
  • Experience with Git workflows and deployment pipelines.
  • Familiarity with tools such as MySQL Workbench, Docker, and Graylog (or similar logging tools).
  • Strong analytical thinking and problem-solving mindset.
  • Ability to work effectively under pressure with tight deadlines.
  • Clear written and verbal communication skills, especially when working with non-technical stakeholders.
Nice to Have
  • Experience building or maintaining exports, reporting tools, or custom client scripts.
  • Familiarity with ACH (Automated Clearing House) processing.
  • Prior experience in client-facing support, success, or technical troubleshooting.
  • Experience documenting technical fixes for non-technical audiences

Perks & Benefits

  • Compensation tied to market data
  • We reward for contribution
  • Flexible Time-off
  • We’re committed to career development
  • Work from home
