Senior Full-Stack Engineer (Contract)

• You work best with fierce independence. You don’t need hand-holding - you’re the one who does the hand-holding when it’s needed. You don’t wait for direction; you are the direction. To twist a phrase: you’re not the one who knocks, you’re the one who delivers
• You live for making things work. Whether that’s a clean new feature, a quirky legacy bug fix, or tracking down why that button refuses to do what it’s told. You like code that’s neat and maintainable, but you’re also practical - you know sometimes duct tape is exactly what the situation calls for
• Building apps is your thing - you tinker, refactor, and optimize because you can’t help yourself. You get a kick out of speeding things up, cleaning things up, and occasionally wondering what exactly your predecessor was drinking when they wrote that function
• And yes, you’re not afraid to dive into the relics. That PHP app last touched in 2010? It still needs love. The JavaScript file with 1,200 lines and no semicolons? You’ll wrestle it into submission
• Manage your own time while adhering to priorities set by the company
• Build new features and improve existing ones across our platforms
• Refactor and enhance applications to keep them performant, scalable, and maintainable
• Write tests (unit, integration, and end-to-end) to ensure software reliability
• Be involved in every phase of the software lifecycle, from ideation to deployment
• Participate in deep technical discussions and help shape our applications and infrastructure
• Get hands-on with all elements of the stack, from backend logic to frontend interactions
• Identify inefficiencies and help streamline workflows, reducing unnecessary work
• Take ownership of your work, ensuring high-quality results and maintainable solutions
