Today, with more than 10 years of experience connected to Silicon Valley, Cheesecake Labs has delivered 300+ digital products for a diverse range of clients, from Fortune 500 to fast-growing startups, that have the challenge of innovating in the world’s most competitive markets.

Our commitment to high-quality services has earned us recognition as the Top 1 Mobile Development company in Latin America and among the top 10 globally for Mobile App and Custom Software Development by Clutch and a GPTW-certified company for 10 years in a row. At Cheesecake Labs, our engineers don’t just execute tickets. We’re usually brought in when products are still evolving, requirements are not fully defined yet, and teams need to balance speed, scalability, user experience, and business priorities all at the same time. Many of our client engagements start with strategic conversations and evolve quickly into active projects. That’s why we maintain a network of strong contractor engineers we can engage quickly when the right projects come in. This is not a traditional long-term internal role. It’s a contractor opportunity designed for people who enjoy working across different products, clients, technologies, and business challenges in fast-moving environments. We’re looking for a Senior Software Engineer Fullstack (.NET) (Contractor) who combines strong engineering fundamentals, product mindset, and ownership across scalable systems and modern applications. Engagement details Contractor / project-based engagement Paid in USD/hour Remote-first Flexible allocation depending on project availability and fit Opportunities may vary in duration, scope, and weekly commitment depending on client needs Some opportunities may start immediately.Others may become active as new projects enter our pipeline. What this role actually looks like This is not a “receive tasks and code” type of role. On a typical project, you might: Build and evolve scalable web applications across frontend and backend environments Work closely with team members to figure out what should actually be built Develop fullstack solutions using .NET and modern web technologies Work across APIs, databases, infrastructure, integrations, and cloud environments when needed Make trade-offs between scalability, maintainability, performance, and delivery speed Review code, challenge decisions, and contribute to raising the engineering bar Participate in technical and product discussions with international clients and multidisciplinary teams Some projects will be heavily backend-focused.Others will require broader collaboration across frontend, infrastructure, and product ecosystems. Most are a mix of both. What tends to work well here We’ve seen that people who thrive in this type of engagement usually: Have strong experience building scalable applications in C# and the .NET ecosystem Have a fullstack mindset — even if backend is your strength, you’re comfortable navigating frontend concepts and working across the stack when needed Feel comfortable working across APIs, databases, integrations, cloud environments, and scalable architectures Care deeply about code quality, maintainability, and pragmatic technical decisions Feel comfortable navigating modern frontend ecosystems such as React.js or other SPA frameworks Feel totally confident working in English with international clients and teams (calls, discussions, async) — at least advanced level Already use AI as part of their day-to-day workflow — whether for development, debugging, prototyping, documentation, or workflow acceleration Experience with React.js, Docker, AWS, or modern cloud environments is a strong plus. This probably won’t be your thing if Just to be transparent: You’re looking for a highly stable long-term internal role with fixed scope and predictable allocation You prefer highly structured environments with rigid processes and very defined requirements You’re uncomfortable navigating ambiguity or fast-changing technical contexts You’d rather avoid client interaction or cross-functional collaboration You dislike context-switching between technologies, projects, and business domains There’s nothing wrong with any of that — it’s just not how these engagements usually operate. One last thing To participate in this selection process, you must: Have a valid business registration in your country (CNPJ, VAT, EIN, or equivalent) Have a bank account eligible to receive USD payments Be able to issue invoices accordingly These requirements are necessary for contractor engagement and payment processing. Not sure if you check every box? That’s okay. We know that many great people — especially from underrepresented groups — hesitate to apply unless they meet 100% of the requirements. If this opportunity sounds interesting, we’d still love to hear from you. IMPORTANT TIP -> The communication during the selection process is done by email.
