Senior Platform Engineer

Role description

Senior Cloud Platform Engineer (AWS) | Amsterdam | up to €160,000 OTE

What if cloud infrastructure wasn't just something you operated, but something you truly owned?

For a fast-growing Amsterdam-based technology company, we're looking for a Senior Cloud Platform Engineer who combines deep AWS expertise with a strong understanding of performance, scalability and cloud economics.

You’ll work on a mission-critical e-commerce data platform processing large volumes of product and commercial data every day. At this scale, infrastructure decisions matter: milliseconds impact performance, architectural choices impact reliability, and AWS decisions can have a significant impact on the bottom line.

This isn't a role where you'll simply keep the platform running. You’ll help determine how it should run, scale and evolve.

What you’ll own

You’ll take senior technical ownership of the cloud platform, working closely with Engineering leadership and the wider engineering organisation.

Your focus will include:

• Designing, improving and scaling the AWS cloud infrastructure
• Driving reliability, availability and performance across the platform
• Optimising AWS usage and cloud spend without compromising performance
• Creating visibility into cloud consumption, capacity and cost drivers
• Identifying opportunities for architectural and infrastructure improvements
• Improving Kubernetes environments, observability, networking and latency
• Helping engineering teams make better infrastructure and cloud decisions
• Translating technical choices into their commercial and operational impact
• Acting as a senior technical sparring partner for Engineering leadership

You’ll remain hands‑on, but you're expected to look beyond the technology itself. We want someone who understands that a great cloud platform needs to be technically excellent, operationally reliable and financially sustainable.

The environment

You'll be working with technologies including:

The environment is high-load, data-heavy and business-critical, with plenty of room to improve, optimise and build.

What we’re looking for

We’re interested in speaking with engineers who bring:

• 7+ years of experience in Cloud Engineering, Platform Engineering, DevOps or SRE
• Deep hands‑on expertise with AWS
• Strong production experience with Kubernetes
• Experience operating high‑load, high‑availability or data-intensive platforms
• Strong knowledge of observability, networking, performance and scalability
• Proven experience with AWS cost optimisation, cloud economics or FinOps principles
• The ability to analyse cloud consumption and turn it into concrete technical decisions
• Confidence communicating with senior engineering and C-level stakeholders
• A pragmatic mindset and the ability to take ownership without needing a highly structured environment around you
• Experience in e-commerce, marketplaces, travel, adtech, product data or other high-volume digital platforms is a strong plus.
• AI is already changing the way strong engineering teams operate, so we're also interested in how you use AI tooling to make yourself and the teams around you more effective.

Why this role?

The company is commercially successful and continuing to scale. That creates interesting engineering challenges: more traffic, more data, greater infrastructure complexity and an increasing need to make deliberate decisions around cloud architecture and cost.

You’ll have the mandate to influence those decisions rather than simply execute them.

Compensation: up to €160,000 OTE per year

depending on experience and seniority.
