Senior Software Engineer II (Golang, Partnerships) at Spoton

About SpotOn We’re not just building restaurant tech, we’re giving independent restaurants the tools to compete and win. From our award-winning point-of-sale to AI-powered profit tools, everything we do helps operators boost profit, work smarter, and keep their best people. And every solution is backed by real humans who actually give a sh*t about helping restaurants succeed. - Named the #1 Restaurant POS by G2 (Fall 2025), based on ratings from real users - Rated the top-rated point-of-sale (POS) for restaurants, bars, retail, and small businesses by Capterra users - Awarded Great Places to Work and Built In’s Best Workplaces for multiple years running We move fast, care hard, and fight for independent restaurant operators to do what they love, and love doing it. If you’re looking to make an impact with heart and hustle, SpotOn is the place for you. The ideal candidate will be able to: - Take end-to-end ownership: You don't close tickets and walk away. You own outcomes. When a partner integration breaks or a feature misses the mark, you see the fix through, wherever the problem lives in the stack. - Work through real complexity: You'll build and maintain partner-facing APIs and integration systems at scale. Expect evolving third-party contracts, upstream inconsistencies, and reliability constraints. This is not simple CRUD work. - Treat AI as a core development partner: You have hands-on experience with agentic coding workflows, custom skills and hooks, and design of development systems where AI writes the bulk of the code while you steer architecture, review, and quality. - Drive technical direction: You contribute to architecture decisions, address tech debt before blocking the team, and raise the bar through code reviews and mentoring. - Be a "whatever it takes" teammate: When a deadline gets tight or a cross-team dependency surfaces, you step in, figure out what's needed, and clear the path for the team. What skills are we searching for? - Production experience: 5 to 7 years building software running reliably in high-traffic production environments. - Go depth: 3+ years of hands-on Go, including goroutines, channels, and Go testing frameworks. You write idiomatic, maintainable, performant code. - API and integration chops: Strong experience designing and maintaining scalable APIs and integration layers with external services. You understand how distributed systems fail and how to make them robust. - AI-native workflow: You build with AI at the center of how you work, not on the side. You've shipped production work through agentic development systems and know how to design skills, hooks, and custom tooling around your own workflow. - Solid fundamentals: Strong grasp of data structures, algorithms, and design patterns applied to distributed systems. - Agile delivery: Comfortable working in Agile methodologies. - Communication: Solid command of written and spoken English, min. B2. Perfect candidate also has: - Partner ecosystem experience: You've worked on systems connecting to third-party platforms or public APIs, and understand the reliability and versioning trade-offs involved. - Full-stack range: Comfortable jumping into TypeScript or React when a project needs you there. - Cloud and infra comfort: Time spent with AWS, Terraform, or Kubernetes, and a grasp of how your code behaves in production. - Database depth: Solid experience with SQL and NoSQL (MongoDB a plus), including reasoning about consistency and performance trade-offs. - Mentoring mindset: You raise the bar for those around you through thoughtful code reviews and shared knowledge. Here’s a bit about what we have to offer: - Competitive pay: 23 800 - 29 800 PLN net on B2B. - Training budget 3500 PLN gross per year. - Access to e-learning platforms (O’Reilly). - Fully paid private healthcare in LuxMed. - Access to the Worksmile platform with a monthly top-up. - Subsidized access to breakfast and lunch through the vending machine in Kraków office, and lunches in Gdańsk office once a week. - Group English classes with a native speaker. - New Macbook Pro, 4K monitors or whatever tools you need. - Flexible working hours. - New, modern, bright and comfortable office space in the city centre. - Access to the company’s library. - Great working atmosphere. - Chill out room with a PlayStation and games. - Free snacks and beverages in a kitchen. - Company parties and social activities. - Employee referral program. - Relocation Package within Poland.
