About CookUnity

Food has lost its soul to modern convenience. And with it, has lost the power to nourish, inspire, and connect us. So in 2018, CookUnity was founded as the first-of-its-kind platform that connects the world with the source of truly great food: chefs. Today, CookUnity delivers 35 million meals a year from the industry’s best chefs to homes all over the country. Fresh. Ready-to-eat. And crafted with the passion that nourishes body and soul.

Unwilling to stop there, CookUnity is expanding beyond delivery to become an ever-innovating marketplace focused on our singular mission: empower Chefs to nourish the world.

If that mission has you hungry in more ways than one, you’ve found the right job posting.

About The Team:

The Revenue Engine Squad is responsible for the core systems and user experiences that power monetary transactions within CookUnity’s eCommerce marketplace, including pricing, payments, refunds, promotions, and the order finalization process. As part of the Marketplace Zone, the team plays a critical role in building a flexible and scalable financial infrastructure that evolves with the needs of our marketplace.

To support CookUnity’s growth, we are reimagining and elevating our revenue systems to be more scalable, intelligent, and adaptable. This is a unique opportunity to tackle complex engineering challenges, shape the future of our financial infrastructure, and have a direct impact on the evolution of a fast-growing marketplace.

The Role:

As a Staff Full-Stack Engineer on the Revenue Engine Squad, you will lead technical initiatives, drive architectural decisions, and mentor engineers as we scale our revenue infrastructure. You’ll work across both backend services and frontend applications, tackling high-impact and technically challenging problems related to pricing models, promotions, payments, refunds, and order finalization.

This role is ideal for a well-rounded engineer who is comfortable navigating both backend and frontend development. On the backend, you’ll design scalable, resilient services that power our financial infrastructure. On the frontend, you’ll build intuitive, high-performing user experiences for payment, wallet, account management.

You will collaborate closely with engineering leadership, product managers, and cross-functional teams to build and improve mission-critical systems that directly impact CookUnity’s revenue operations. We’re looking for someone who can work across the stack, lead projects from concept to deployment, and set a high technical bar for the team while driving best practices in software engineering.

• Infrastructure: AWS Based: Kubernetes, S3, CloudFront and RDS.
• Agile Methodology

Please note that only candidates based in Latin America will be considered for this role.

Responsibilities:

• Lead the design and implementation of scalable, end-to-end solutions across backend services and front-end applications that power CookUnity’s revenue-related operations.
• Develop and optimize user-facing features, such as wallet, credits, payments experiences.
• Define and drive architectural improvements that enhance system reliability, scalability, and maintainability.
• Collaborate cross-functionally with Product, Finance, and BizOps teams to translate business requirements into robust engineering solutions.
• Mentor and guide other engineers, setting a high standard for technical excellence and a culture of proactive ownership.
• Evaluate and introduce new technologies, frameworks, AI adoptions that improve our technical stack and development velocity.
• Improve system observability, performance, and resilience, ensuring uptime and smooth operation of revenue-critical systems.
• Contribute as a hands-on engineer, writing clean, well-tested, and efficient code, leading by example.
• Lead technical planning and project execution, breaking down complex problems into manageable solutions and driving initiatives to on-time completion.
• 8+ years of experience in frontend and backend development, with expertise in Kotlin, React, Next.js, and SQL databases.
• Proven experience in architecting and scaling complex backend systems in a high-growth, fast-paced environment.
• Experience developing and maintaining front-end applications with React, Next.js, and GraphQL.
• Strong knowledge of distributed systems, service-oriented architecture, and event-driven architecture.
• Deep understanding of system performance and scalability best practices.
• Proven ability to translate complex, ambiguous requirements into clear, actionable plans that drive alignment and timely delivery.
• Advanced English communication skills, with the ability to clearly articulate complex ideas to both technical and non-technical audiences.
• Demonstrated experience in mentoring and guiding engineers.

Preferred Requirements:

• Experience working in eCommerce, marketplace, or fintech environments.
• Hands-on experience with Saga pattern and orchestration frameworks like Temporal.
