About the Team/Role
WEX FSM (formerly Payzerware), is an end-to-end Field Service Management platform that helps contractors run their business, grow sales, and simplify back-office operations. WEX FSM provides comprehensive business management including schedule / dispatch, invoicing, sales proposals / invoices, and maintenance agreements. We also enable a full range of payment and financing solutions, which further help contractors decrease outstandings, generate more revenue per job, and save time.
We are seeking a Senior PHP Software Engineer to join our team. In this pivotal role, you will join the team responsible for designing, developing, and deploying our flagship SaaS product, WEX FSM. You will play a key role in building robust, scalable APIs that not only enhance our product but also empower our partners to integrate with our platform efficiently. You will partner with Product Managers to translate business requirements into technical reality, ensuring ambiguity is removed before a single line of code is written. You will also serve as a mentor to fellow engineers, enforce coding standards through rigorous code reviews, and proactively reduce technical debt to keep our platform healthy and scalable. If you get excited about building modern, resilient applications, possess a deep passion for data layer performance, and thrive in a collaborative, fast-paced environment, we encourage you to apply.
How You'll Make an Impact
As a Senior PHP Software Engineer, you will be instrumental in modernizing and improving the performance and stability of our core SaaS product, WEX FSM. Your expertise in the Symfony PHP Framework will be key to refactoring and enhancing existing application features, ensuring they are robust, scalable, and maintainable.
You will specifically act as a subject matter expert on data persistence, utilizing your deep understanding of Doctrine ORM to optimize complex queries and eliminate performance bottlenecks. You will dive deep into MySQL to analyze execution plans and refine indexing strategies. Your contributions will be critical in delivering a faster, higher-quality user experience.

Excellent communication and collaboration skills working with internal and external teams.
Act as a technical leader for the team, assisting in the onboarding of new hires and conducting code reviews that not only check for potential errors but enforce established coding standards and best practices.
