Staff Infrastructure Engineer

Staff Infrastructure Engineer

Location: Soho, New York City (Onsite – 4–5 days per week)

Salary: $230,000 – $280,000 Competitive Equity

Employment Type: Full-Time, Permanent

The Opportunity

Are you an experienced Infrastructure Engineer with a strong software engineering background who enjoys building and scaling infrastructure rather than simply maintaining existing systems?

We're working with an exciting, high-growth technology company in New York looking to appoint its first dedicated Staff Infrastructure Engineer.

This is a unique opportunity to take ownership of the company's infrastructure strategy, working closely with senior engineering leadership to design, build and scale the systems supporting its next phase of growth.

The business currently supports approximately 500 customers and processes over 1 billion invoice items every month, with both customer numbers and data volumes expected to grow by 2–3x over the next 12 months.

You'll play a critical role in ensuring the infrastructure can support this growth while improving reliability, security, automation and overall platform performance.

We're particularly interested in engineers who have previously worked within high-growth Series A–C startups, taking infrastructure from early-stage environments through significant periods of scaling.

The Role

As Staff Infrastructure Engineer, you'll take technical ownership of the company's cloud infrastructure, helping shape its architecture, reliability and long-term scalability.

Your responsibilities will include:

• Designing, building and scaling AWS infrastructure to support significant increases in customers and data volumes.
• Leading the evolution of the company's Kubernetes and Terraform architecture.
• Supporting the migration away from ECS/Fargate towards a more scalable container orchestration environment.
• Building and strengthening security infrastructure to support enterprise customers and compliance requirements.
• Taking ownership of platform reliability, observability and operational performance.
• Defining and implementing Service Level Objectives (SLOs), monitoring, alerting and incident response processes.
• Developing production-quality software and automation to reduce manual processes and operational risks.
• Improving infrastructure deployment processes, configuration management and infrastructure as code practices.
• Identifying and resolving performance bottlenecks across cloud infrastructure and distributed systems.
• Establishing best practices for infrastructure security, scalability and reliability.
• Working closely with the VP of Engineering and Platform Engineering team to influence technical strategy and architecture decisions.
• Helping establish the engineering standards and infrastructure foundations required to support the company's continued growth.

What We're Looking For

We're looking for a technically strong engineer who combines software development expertise with hands-on experience building and scaling modern cloud infrastructure.

Essential experience:

• 8 years of professional engineering experience, ideally beginning your career in software engineering before moving into infrastructure or platform engineering.
• Strong hands-on experience with Terraform and Kubernetes in production environments.
• Experience designing, building and scaling cloud infrastructure, ideally within AWS.
• Previous experience working within a high-growth Series A, B or C technology startup.
• Proven track record of building infrastructure from the ground up or scaling existing environments through significant growth.
• Experience managing Kubernetes environments ranging from a small number of clusters to larger distributed deployments.
• Strong understanding of infrastructure security and cloud security best practices.
• Ability to write production-quality code and develop automation tools.
• Experience making architectural decisions and taking ownership of complex infrastructure projects.
• Comfortable working in a fast-paced engineering environment with significant technical responsibility.

Desirable experience:

• Software development experience using TypeScript, Python, Rust or Java.
• Experience with Docker, Helm and GitHub Actions.
• Knowledge of AWS ECS and Fargate.
• Experience implementing observability platforms covering metrics, logging, tracing and alerting.
• Experience establishing SLIs, SLOs and incident management processes.
• Familiarity with Kafka and distributed messaging systems.
• Previous experience supporting infrastructure through rapid business growth.
• Experience developing security infrastructure to meet enterprise and regulatory compliance requirements.

Technology Environment

You'll be working with a modern engineering stack including:

Cloud Infrastructure: AWS, ECS, Fargate

Containers & Orchestration: Kubernetes, Docker, Helm

Infrastructure as Code: Terraform

Software Engineering: TypeScript, Python, Rust

• Competitive base salary of $230,000 – $280,000
• Competitive equity package
• Opportunity to become the company's first dedicated Infrastructure Engineer
• Significant ownership of infrastructure architecture and technical strategy
• Direct collaboration with the VP of Engineering
• Opportunity to build and scale infrastructure supporting billions of transactions
