Sword - Senior Backend Engineer

• Ownership and accountability: you own outcomes, not just tasks. When something you built breaks or doesn’t deliver value, it’s yours to fix, and you don’t wait to be asked; • Sense of urgency: you move fast, make decisions with incomplete information, and prefer shipping and learning over polishing in isolation; • Speed over scalability: we optimize for speed of delivery, go-to-market and product-market fit, not for scale we don’t need yet. You default to the fastest path to a working experiment; • Doing things right where it counts: speed doesn’t mean carelessness. You know which corners are safe to cut today and which ones would slow us down tomorrow, and you keep quality and reliability where they matter, especially in a clinical context; • Experiment mindset: you treat features as hypotheses, build small, measure, and are comfortable throwing work away if it doesn’t prove value; • Going beyond your role: you don’t stop at “my part is done”. You help product, design and clinical teammates get unblocked so that our product projects are successfully closed, not just handed off; • Clear, direct communication: you flag risks early, explain trade-offs in plain language to non-technical colleagues, and keep everyone aligned without heavy process. • Extensive experience (5+ years of experience) with web development (experience with Golang or/and NodeJS are mandatory); • Knowledge of SQL language and managing SQL databases (experience in NoSQL databases a plus); • Ability to write high-performance, reusable code; • Knowledge of Software Engineering patterns with special focus on Web Services development; • Knowledge of caching software like Memcached or Redis are a plus; • Knowledge of continuous integration / deployment process and tools; • Excellent communication skills, problem solving and proactive attitude; • Good level of written and technical English; • You should know how to design and implement AI-powered workflows or automations that meaningfully improve efficiency and outcomes; • AI coding agents experience is required; • Spec driven development is valued; • Proficiente coding agent usage is valued. • The range below reflects base, variable, and equity for this role. • This is a starting point, not a ceiling — once someone joins and proves they're outlier talent, we adjust quickly to make sure their compensation matches their impact. • Job titles may span more than one career level, so actual pay depends on skills, qualifications, experience, location, and market demand, among other factors. The range reflects base salary plus any variable, bonus, or sales incentives, and our estimate of the value of private company stock options where applicable. It's subject to change, and future stock value isn't guaranteed. Sword also offers additional benefits beyond total compensation.
