Senior Software Engineer - API & Marketplace Values Benefits Jobs Offices Jobs > Senior Software Engineer - API & Marketplace Senior Software Engineer - API & Marketplace Permanent Full time €60,500 - €77,000 08005, Barcelona, Barcelona, Spain Engineering Hello! 👋🏽 Would you love to improve the way companies take care of their people, their most valuable asset? At Factorial, we're looking for a Senior Software Engineer to join our API & Marketplace Team within the Platform Domain. You will work on both sides of the stack but with more focus on the backend side. Sitting within the Platform Domain , you will lay the foundations for external and internal users to extract and deliver value from our platform. This means you will be doing product twice, addressing not only user needs, but also designing the best tools for both internal and external developers. The role requires full ownership of your area, a self-starter attitude, dealing with uncertainty and combining a strategic product mindset with a focus on execution. If you feel as if you belong in a product-first company, want to work with a world-class team of designers and developers, and deliver the future of B2B software, we should talk! The Engineering team at large 🙌🏼 At Factorial, you'll be part of a team of 200+ Product Engineers. We look for talented people who are curious, proactive, and have great communication skills. People who are at the forefront of developing tools that help teams become the best versions of themselves. You'll work in a multicultural, English-speaking environment where your technical acumen, creative problem-solving abilities, and passion for user-centric products will directly contribute to our mission of improving HR processes for SMEs worldwide. The Role 📜 You will be building not only integrations, but also facilitating developer partners to have the best possible experience building their own. Our stack is mainly Ruby on Rails and React. We don’t look to match the stack. On the contrary, the experience with multiple languages and frameworks brings perspective and a set of tools in the tool belt. Besides, we are continuously evolving the ecosystem of engineering, adopting new architectures and paradigms, and evolving current ones. You are expected to contribute to the next software architecture stage at Factorial. How We Work 💻 (Barcelona or Madrid Office) At Factorial, we believe the best products are built when people come together, in person to collaborate, challenge ideas, and move fast. That’s why our Engineering Teams follows an office-first, flexible approach . We work on-site several days a week , using that time to connect, align, and innovate as a team. However, we also understand the importance of focus and flexibility, so we support remote work when it makes sense - whether for deep work, personal needs, or just a change of scenery. This balance helps us stay agile, creative, and closely connected, while giving everyone the space to do their best work. Work ethics At Factorial, we know that building a great product means building a great team. We value some key principles that help us thrive together. Radical (and Passionate) Candor : We're excited about creating great products and advancing our mission. This means being proactive, obsessing about quality, and experimenting. We tell our managers and peers things we think we cannot say, practicing radical candor to drive innovation and improvement. Effective Communication : Clear communication, especially in writing, is crucial. We communicate openly, build narratives, and aren't afraid to debate ideas. If we can't explain something clearly, we seek to understand more deeply until we can. And remember, English is our vehicular language, so you need to be comfortable with it! Product Vision : We understand our users' needs and actively engage with them. We constantly look for business opportunities, always asking "What can be next for Factorial?" Reliability and Accountability : We deliver on our commitments while maintaining high quality. We feel accountable for the culture and make others feel accountable too. When we see something broken, we stand up to fix it, feeling responsible for all of Factorial. Problem-Solving : We don't limit ourselves to our nominal job definition. We bring, execute, and later communicate solutions, seeking approval only for decisions that would be hard to reverse. Teamwork Ease : We collaborate well, adapt easily, and are open to feedback. We convince or get convinced, asking the same from everyone. If an initiative comes top-down, we debate it until we fully buy-in, then champion it to our teams. Fighting Complacency : We challenge the status quo and fight complacency with our whole hearts. We're vocal when something is going wrong, seeing it as an opportunity for a better world. Having Fun : While our work is serious, we trust our gut when we have a 10x motivation to try something new. We jump on opportunities for innovation, involving as many people as possible. Your first steps in Factorial: You’ll start with a 2 weeks onboarding period, where you will: Read a lot: Learn about Factorial, our product, our team, and our clients. Learn a lot: Pair with each team member at least once, to understand what they are working on. Code a lot: Solve low-stake bug tickets or quick wins. Fail a lot: We work with local development environments so you can start coding fast. And failing, going back, retrying… We understand this is part of the path, so, we will encourage you to be brave! Talk a lot: Be fully integrated into the team’s rituals from day one. After your onboarding, your day-by-day work will look like the following: You will be a product engineer, taking ownership of big initiatives, and being interested in the outcome, not just the output. About the outcome, you’ll also work with your team members to establish goals and plan a quarterly roadmap , putting special attention to the technical needs of our domain. A Senior Engineer at Factorial influences requirements definition and is autonomous in delivering a polished solution that matches those. You participate in the team’s decision through Requests For Comments (RFCs) that you write yourself or read others’. You will be involved in customer calls to learn about their pains & needs. You will review code daily and get feedback on your code at every pull request, from all team members, including juniors. You will learn from the entire team , both on technical topics (performance, architecture…) and core skills, in an environment driven by engineering quality. You will also mentor junior team members and help them learn from your experience. About us 🚀 At Factorial, we’re building the leading business management software for companies of all sizes.
