If you'd like to be considered when we have new openings, apply now and we'll get in touch when the time comes. Thanks! Guillermo, head of technology ➡️ Can you be a haddock engineer? Engineers at haddock are action-oriented , curious , autonomous , and take full ownership of their work. They are champions of figuring out the unknowns. They talk to customers, deliver quality work, improve our tooling, and are ambitious. We look for people with these same motivations and ways of working. We strongly adhere to the Lean Startup and Agile principles , favoring action over analysis, imperfect iteration over perfect delivery, face-to-face communication, and a fast-paced environment. We work on initiatives in small mission-oriented squads of 1 to 3 people . Engineers are owners and work across the stack in order to achieve our objectives: Architect technical solutions Build backend and frontend code (80% backend, 20% frontend) Engineer AI workflows, balancing latency, cost and accuracy Do your own project management, rolling out your initiatives to customers Track users, measure interactions and extract conclusions Talk to customers to validate ideas and get feedback Our processes and tools are constantly improving, and everyone contributes to making them better. Keep-the-lights-on work is shared, like bug fixing, monitoring and dependency management. We succeed at this by having a rotating squad of Defenders that tackles this kind of maintenance work. ➡️ Example work Some example high-level objectives that you could work towards in your first months are: Enabling Fina to match bank movements with invoices, finding gaps and reporting them to the suppliers via AI phone call. Enabling business data to tell the story of the restaurant to their owners , displaying them financial metrics and insights, and enabling AI agents to work on that data. Increasing adoption of inventories to 50% of customers, a crucial part of operations at a healthy restaurant business. Building MVPs for traceability, enabling groups of restaurants to comply with food health inspections, and evolve it beased on feedback. ➡️ Why join now? If you’re excited by ownership, autonomy, and building technology that directly impacts real businesses every day, this is the right moment to join. Come on board while we're still a startup. It's much more fun and motivating than joining an already established scale up or corporation where your role is very defined and limited! This is more than a job. It’s a chance to leave your mark on an industry that’s ripe for transformation. Our best perk is our work environment and the opportunities you'll get to learn and grow at haddock. ➡️ Requirements 👉 3+ years of engineering experience working on SaaS applications in Agile environments. It's ok if you have 10+ years of experience in total, we just require previous work in SaaS Agile environments. 👉 Product Engineering experience: end-to-end from ideation, infrastructure, backend, frontend, testing, etc. because we aren't "factory developers", we are engineers of digital products responsible for outcomes, not for implementing requirements. 👉 Experience setting up or working with infrastructure : for example, using services, serverless functions, databases, external APIs, caches, queues, events, etc. 👉 Very good use of AI tooling: you have developed good judgement (criterio) when using IA and are very productive with it. 👉 Fluent in Spanish and comfortable in English. We tend to speak in Spanish at the office and in Slack, and write documentation and projects in English. ⭐️ You'll stand out if you've already built AI workflows for production, because at haddock we already have 15+ AI workflows in production and that number is just going to keep growing. ➡️ What is haddock? haddock is the market leader solution for point of control in restaurants, handling all back-office vital operations like product management, inventories, purchases, price tracking, document conciliation, bank conciliation, paychecks, clocking in/out, P&L reports, etc. Not only we have a system of record that helps operate restaurants with control and clarity, but we're also the leaders in offering AI Agents, starting with Fina . They work 24/7 doing the heavy, tedious work that our customers don't have time to do well. This is no AI hype. Our customers obtain visible value from our AI Agents, both in money and time saved. We're becoming strategic partners in the design of their businesses. 👉 Our mission is to empower millions of restaurateurs to level up their business. 👉 Our vision is to lead the market through innovation, strong relationships and by becoming the go-to tech partner for restaurant success. 👀 haddock is backed by Y Combinator , the accelerator behind Airbnb and Twitch.
