Senior Full Stack Software Development Engineer Jobs

About Wolt At Wolt, we create technology that brings joy, simplicity and earnings to the neighborhoods of the world. In 2014 we started with delivery of restaurant food. Now we’re building the delivery of (almost) everything and you’ll find us in over 500 cities in 30 countries around the world. In 2022 we joined forces with DoorDash and together we keep on dreaming big and expanding across the globe. Working at Wolt isn’t always easy, but it’s definitely exciting. Here you’ll learn more, build more, and ship more than in most other companies. You’ll be challenged a lot, but also have a lot of fun on the way. So, if you’re a self-starter with drive and entrepreneurial spirit, this could be the ride of your life. New Verticals is everything our customers buy that isn't a restaurant meal: groceries, pharmacy, electronics, the shop on the corner. It's one of the company's growth engines and still largely unsolved as a product problem - a forty-item grocery basket is nothing like ordering dinner. As a Senior Mobile Engineer, iOS - you'll join New Verticals EMEA, the group accountable for that mission across Wolt and Deliveroo in 30+ countries, organised as five teams. Your home team owns quality and cost: making sure customers actually get what they ordered, at a sensible cost of getting a basket to their door. Substitutions, unavailable items, order accuracy - invisible when it works, infuriating when it doesn't. You won't only work there: mobile expertise is in demand across all five teams, and part of the role is going where the iOS work is. This role is primarily focused on native iOS development. Experience across both iOS and Android, as well as backend development, is a strong plus. What you’ll be doing Building, improving and maintaining native iOS features for customer-facing journeys within our shared consumer apps. Partnering closely with product, design and engineering colleagues to turn customer and business needs into simple, reliable and scalable mobile e

About Ramp Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $200B in annualized spend flows in and out of 70,000+ companies: authorizing payments, flagging risk, categorizing spend, and closing books. The problems are high-stakes, data-dense, and unforgiving. We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you’ve built. At Ramp, everyone is a builder who owns problems end to end and makes consequential decisions that shape the outcome. The median Ramp customer saves 5% and grows revenue 16% in their first year – far in excess of businesses operating without Ramp. We believe every ambitious company deserves the same. If you want to build systems that directly shape how companies move and manage billions, Ramp is the place to do it. About the Role The next chapter of Ramp's growth runs straight through the customers we already have: 80,000+ finance teams who adopted us for one thing and haven't yet seen what the rest of the platform can do for them. Account Management owns that opportunity - and this role owns the team building the motion to capture it. You'll lead a group of 5-8 Account Managers, each carrying a book of ~300 Mid-Market customers with real latitude over how they grow it. This is a build role, not a maintain role: the playbooks, coaching systems, and performance bar you set are the ones this team runs on next year. Your ceiling is set by how well you turn individual AM judgment into a repeatable, scalable motion that grows the segment. What You’ll Do Build and run a high-performing team of 5-8 Account Managers - setting the bar for culture, morale, and daily execution. Get embedded in the relationships that matter. Engage directly with key customers and top accounts alongside your team, especially where trust is being built or repaired. Own the number. Manage qu

If you want to build systems that directly shape how companies move and manage billions, Ramp is the place to do it. About the Role Ramp is building institutional partnerships with the GSI (Global System Integrators), Big-Four consulting firms, and global advisory firms that shape finance transformation, ERP modernization, and technology decisions for the CFOs and finance leaders we serve. These organizations are often in the room when enterprise clients are redesigning their finance stack, selecting technology, or moving from strategy into implementation. This portfolio spans the largest global professional services firms (e.g., Deloitte) and GSIs (e.g., Infosys). They are complex organizations with distinct service lines (e.g., ERP, Tech Modernization, Finance Transformation) each with its own leadership, incentives, and economics, so earning credibility inside one is as much about navigating the firm as it is about the relationship. This role will own Ramp's relationship with that network of firms, building firm-specific go-to-market motions that can include executive engagement, account mapping, co-sell, implementation alignment, thought leadership, and events
