## About the role Have you caught yourself in the grocery store daydreaming about code… yeah, us too. At Fixify, we believe that technology is about more than code and algorithms — it's about enabling connections between people. That's why we're on a quest for a Senior Software Engineer who finds joy in building technology and knows the work doesn't end at git commit. For you, the product's potential isn't fulfilled until it's in the hands of users, helping them work better, collaborate effortlessly, all while putting a skip in their step. As a Senior Software Engineer, you'll work collaboratively with other engineers on all aspects of our product. You'll take ownership of feature delivery in horizontally scalable messaging pipelines while also ensuring the rounded corner of every button in the UI is just right. No doubt you'll come with lots of great ideas of how to evolve the product as you get to explore Fixify's exciting range of features, including large language models (LLMs). We're also big believers in staying close to our customers. So you'll also immerse yourself in our users' environments and refine your work based on their feedback. Attention to detail is key – especially when it comes to communicating clearly with our users. One perk of being a start up is that you'll have the opportunity to see the impact of every adjustment you make, even the smallest one. ## What we can do for you - Welcome you into a team that values every voice and learns from every challenge. - Give you endless opportunities to learn new things. - Provide you with work that influences organizations globally and makes a tangible difference in how people connect and collaborate. - Share the "why" behind every decision so you learn from our collective journey. - Connect you with users for direct visibility into how people use the integrations and how your changes impact their day-to-day lives. ## What you should bring with you - At least 5 years of experience building scalable and observable SaaS solutions with one of the big three cloud platforms (AWS, GCP, Azure). - Strong knowledge of Typescript or a passion to quickly learn and master it. - A practice of "kind engineering" that produces well documented, modular code that's a delight for the next engineer that works on it. - A keen eye for detail – especially when reviewing pull requests. - A genuine interest in understanding user needs and translating them into technical solutions. - The ability to work cross-functionally and lift the team with your positive energy. - A curious nature and a drive to keep improving.
