• Platform Engineer (m/w/d)
• Permanent employee, Full-time · Berlin (hybrid)
• THE IMPACT YOU WILL MAKE

From socks, and petfood, to cosmetics, charles is helping countless brands reach their loyal customers every day, one conversation at a time.

As a Platform Engineer at charles, you’ll help drive our product and infrastructure forward, enabling us to revolutionize conversational commerce.

You’re a generalist with a passion for infrastructure and operations.

You’ll work closely with the other Engineers to build scalable, high-performing systems, while improving system architecture, resolving tech debt, and ensuring seamless user experiences.

Your contributions will result in reliable, data-driven solutions that support millions of users and push the boundaries of messaging-driven commerce.

THIS IS WHAT YOU WILL BE DOING

You’ll build and operate our internal developer platform: the core services, APIs, and infrastructure that every product team builds on top of.

That means writing software, not just configuring it, and standing up infrastructure that holds up under real production load.

• You will be a part of a team that designs, develops, and operates the core services, APIs, and infrastructure that every product team builds on top of.

Examples: building a billing API, maintaining Kubernetes operators, building an authentication broker, optimizing performance in our core monolith, and improving security in our link shortening service.

• You will regularly partner with product teams to investigate issues, learn their use cases, and ship platform changes that hold up in production.
• You'll join our on-call rotation as part of our "you build it, you run it" philosophy.
• You'll have real room to drive cost and reliability initiatives that have measurable, company-wide impact.
• You'll build the automations that make our whole software development lifecycle faster and more robust.
• YOU'LL FIT GREAT WITH THESE SKILLS AND VALUES
• 3+ years of software engineering experience.

You're a generalist - comfortable moving between writing a service, debugging infrastructure, and improving a pipeline in the same week.

• You can build and ship production services in Go or Type Script; not just scripts and glue.

You also know Bash and have the judgment to pick the right tool instead of forcing your favorite one.

• You can build and operate cloud infrastructure that survives real production workloads, ideally on GCP.
• You’ve worked with Git Hub Actions or similar CI/CD tools, and you know what a healthy and efficient pipeline looks like.
• You have a solid grasp of scalable system design, distributed systems, cloud technologies, and how to roll out infrastructure changes.
• You're comfortable with remote work and asynchronous communication. You also know that good collaboration needs visibility and cooperation, not just output.
• You use AI tools effectively without handing over the steering wheel.
• Product and business sense: you understand customer needs and focus on solving the right problems, not just building technically interesting solutions.
• You're a self-directed learner.

You don't need to know our whole stack on day one, but when you hit something unfamiliar, you dig in, ask good questions, and follow through.

We'll give you room and context to grow; you bring the drive.

Meeting all requirements is not necessary to apply. We encourage candidates who meet some but not all of these qualifications to submit their application.
