Job description

Helcim is searching for a Senior Software Engineer to help develop the next generation of payments technology. We're looking for a talented & experienced individual with a passion for coding, enjoys learning & implementing new technologies, has strong problem-solving skills and a user-focused approach to software development. As a Senior Engineer you will be building and deploying high-quality software solutions. You will continually be involved in mentoring and coaching, ensuring you and your team are delivering at a high level. We put an emphasis on developing our team members to build them into well rounded professionals. As a member of our team, you will be working on numerous ongoing and new projects. Helcim is a fast-paced, high-demand company and the successful candidate will work well in that environment.

On this team, you're building the money engine that makes sure merchants actually get paid. We own the full flow- from settlement and funding to accounting, reconciliation, and reserves. Every transaction that hits the platform? We're the ones making sure the math checks out, the bank transfers land, and the ledger stays tight. We plug directly into banking partners, so there's zero room for "close enough"- precision is the whole point. The impact hits different- what we ship is literally how money moves and how the business keeps the books straight.

We believe that diversity and having an inclusive culture is not only the right thing, but key to our long-term success.

Diversity brings more experience, view-points, knowledge and insight about our future.

We also want to provide an accessible interview process, so if there’s any accommodations that would make your experience more comfortable, please let us know.

• Education should include a Bachelor's, technical degree, bootcamp or other certifications in computer programming, computer science or object-oriented software development, or equivalent experience.
• Highly proficient in PHP, Laravel + some Front end javascript experience (Vue/React/Angular/Vanilla JS).
• Strong experience in system design for backend services, including caching strategies, fault tolerance, and performance optimization.
• Proven ability to optimize SQL queries and large-scale data workflows to handle high transaction volumes.
• Familiarity with cloud-native databases and BigQuery is a plus, as well as experience in Golang.
• Experience with Docker and Kubernetes, or other containerization software(s).

• Designs and maintains scalable, high-performance APIs to support both internal and external services, with a focus on correctness, reliability and security using PHP Laravel.
• Builds systems through event driven architecture with PHP as well as Go.
• Coaches and mentors junior developers, providing guidance, support, and feedback to help them grow in their roles.
