Hi there! Thanks for stopping by 👋 Are you an experienced Java, PHP, C#, C++, Ruby, Python, developer looking to make an exciting change: ditching the monolith and building new Golang microservices? We are looking for a Senior Back-end Engineer to join our team in Newmarket. You are expected to perform at a high level and make strong contributions to the team by rapidly and efficiently building solutions to our retailers' problems, focussing on iteration, experimentation, and stability. This role will focus on the back-end, but you may get involved in front-end work if you show interest. You do not need to be an expert in Golang but you must be willing to learn, and you’ll have our full support on this journey. Engineering @ Lightspeed: - We build new features on top of a modern stack, consisting of web apps (React) communicating through APIs to Go services, backed by databases and Kafka topics, all deployed using Docker in a continuous delivery cycle to AWS - You don’t need to have experience in any of our specific technologies: we’re great at teaching good engineers how to use our modern SaaS stack - We work in two-week sprints, but we don’t treat process as rigid. We stay agile and iterative, adapting our ways of working and continuously improving what works best for the team - We deploy changes to production every 7 minutes, on average - Blameless culture and a continuous improvement mindset What you’ll be doing: - Develop and maintain software by coding, implementing new features, reviewing code, fixing bugs, engaging in peer programming, and responding to incidents - Take ownership of features and contribute to impactful coding projects with accountability - Break down projects into manageable, actionable tasks to maximise efficiency and deliver value quickly - Collaborate closely with engineers, product managers, and designers to plan and coordinate upcoming tasks - Continuously learn and share knowledge through chapter reviews, demos, and mentoring fellow engineers - Enhance common services and shared libraries, introduce or upgrade tools and frameworks, improve documentation, and refine best practices and processes What you need to bring: - Senior level of experience as a Back-end Engineer including both successes and failures (“scars”), which help you make better decisions - Deep knowledge in at least one of the following: Golang, Java, PHP, C#, C++, Ruby, Python, Elixir - Experience working on major systems in one or more languages: ideally you’ve built REST API endpoints on top of data storage layers, and understand concepts like authentication, web security, and the way that frontends consume APIs - Ability to mentor and train other Engineers in the team We know that people are more than what’s on their CV. If you’re unsure that you have the right profile for the role... hit the ‘Apply’ button and give it a try! Be a changemaker You’ll enjoy: - Lots of autonomy, flexible work culture with the option of working remotely or from one of our beautiful offices. - Genuine career growth opportunities within a company that's continuously expanding. - Make a meaningful impact by helping merchants grow their businesses through creating or improving products and addressing customer feedback. - Be part of a team large enough for growth yet agile enough for real impact. - Work on high-traffic products with a global user base. - Opportunity to work alongside other highly skilled engineers, learn and expand your skill set, forge wonderful relationships and make your mark within the diverse and inclusive Lightspeed culture, a true Canadian tech success story.
