At Brain Co., your work will be deployed in the real world, not stuck in research. We move fast, with more demand than we can serve, and are looking for exceptional people to take ownership from day one.

About The Role

As an AI Platform Security Engineer at Brain Co., you will play a pivotal role in building and deploying state-of-the-art backend systems to automate various real-world problems. You will work directly with the customer to develop the product spec and build from zero. From designing robust and scalable architectures to optimizing performance and reliability, you will turn research breakthroughs into practical solutions for various nation states. This role is your opportunity to make a significant impact by making AI technology both accessible and influential.

In This Role, You Will

• Innovate and Deploy: Design, develop, and deploy advanced backend solutions that integrate AI to tackle real-world problems, particularly in automating complex, manual processes in government and industrial sectors. Utilize modern backend frameworks, microservices architecture, and cloud computing to build applications that apply AI to intricate optimization challenges.
• Make a Big Impact: Interact directly with key customer stakeholders to apply pioneering AI solutions while working alongside experienced ex-founders, government officials/ministers, AI researchers, and engineers. Understand complex business challenges and deliver backend solutions powered by AI. Join a dynamic team where ideas are exchanged freely, and creativity flourishes. You will wear many hats: software development, system architecture, product management, and interpersonal skills.
• Optimize and Scale: Build scalable data pipelines, integrate industrial sensor networks, optimize application performance and reliability, and prepare systems for production. Engage in projects including but not limited to optimizing the world’s most advanced energy production systems, modernizing core government workflows, or improving patient outcomes in advanced public healthcare systems.
• Learn and Lead: Stay abreast of the latest developments in backend engineering and AI. Participate in code reviews, share knowledge, and set an example with high-quality engineering practices. Mentor junior engineers and lead by example.
• Make a Difference: Monitor and maintain deployed applications to ensure they continue delivering value across various governments worldwide. Work directly with customer engineers and SMEs to develop and tune applications that optimize their workflows and deliver tangible upside. Your work will directly impact how AI benefits individuals, businesses, and society at large.

You Might Thrive In This Role If You

• Have 5+ years of experience and an appetite for working directly with the customer to develop the software spec and build from zero
• Are experienced with backend technologies, microservices, and cloud platforms.
• Have demonstrated experience with modern backend frameworks, cloud compute and storage, RESTful APIs, and database management systems.
• Possess a strong foundation in software design principles, data structures, and algorithms.
• Exhibit excellent problem-solving and analytical skills, with a proactive approach to challenges.
• Have deep experience in implementing security best practices across the platform — from system/network security, to code and deployment pipelines, monitoring, and incident response.
• Can work collaboratively with cross‑functional teams.
• Thrive in fast-paced environments where priorities or deadlines may compete.
• Are eager to own problems end-to-end and willing to acquire any necessary knowledge to get the job done.
• Hold a Bachelor’s/Master’s degree in Computer Science, Software Engineering, or a related field.
