Senior Platform Engineer | AI Infrastructure & Distributed Systems

New York City | On-site

$200,000 - $300,000 base salary (depending on experience) + Founding Equity

About the Company

We're partnering with an exciting, venture-backed AI startup that's rethinking how some of the world's most complex engineering projects are designed and delivered.

They're developing AI-powered technology that takes on time-consuming engineering workflows, allowing engineers to spend less time on repetitive tasks and more time solving the challenges that really matter.

And the opportunity is huge. While AI is transforming industries around the world, much of the engineering sector is still in the early stages of adoption. This company is looking to change that.

Backed by leading investors, they're building their platform and engineering team from the ground up, and we're helping them hire a Senior Platform Engineer to be part of that journey.

If you've ever wanted to get in early, have a real say in what gets built and see your engineering decisions make a difference, this is that kind of opportunity.

Responsibilities

• Design and build scalable backend systems that support AI-powered applications across multiple customers.
• Develop and improve platform architecture, including APIs, data ingestion and multi-tenant systems.
• Work with AWS cloud infrastructure, helping ensure systems are secure, reliable and scalable.
• Contribute to AI infrastructure, including retrieval systems and RAG capabilities.
• Improve the engineering experience through CI/CD, automated testing, monitoring and development tools.
• Collaborate with the CTO and engineering team to solve technical challenges, make architectural decisions and shape the platform's future.

Requirements

• Strong experience in backend engineering, platform engineering or distributed systems.
• Experience designing and building scalable, production-grade software architectures.
• Hands-on experience with cloud infrastructure, ideally AWS.
• Experience contributing to architectural decisions and taking ownership of complex technical projects.
• Familiarity with CI/CD, automated testing, observability and production infrastructure.
• Comfortable working in a fast-moving environment where you'll have the freedom to make decisions and solve new problems.
• Strong communication skills and an interest in collaborating directly with engineering teams and customers.

Preferred Skills

• Kotlin, Python or similar backend programming languages.
• Experience with RAG, retrieval systems or AI infrastructure.
• Next.js, Vercel or modern frontend technologies.
• Experience building internal developer platforms or tools.
• Previous experience in a startup, founding engineering team or early-stage technology company.

What's on Offer

• $200,000-$300,000 base salary, depending on experience.
• Founding equity with the opportunity to share in the company's growth.
• Full healthcare benefits.
• Direct collaboration with the CTO and significant influence over technical decisions.
• Early-stage ownership in a growing AI company.
• On-site working in New York City.

If you're an experienced engineer who wants to take ownership of meaningful technical challenges, work closely with founders and help build the infrastructure behind an ambitious AI platform, we'd love to hear from you.
