We exist to help engineers move quicker, safer, and with deeper visibility. We treat our internal platform as a product, with our engineers as the customers.
The Role We are looking for an engineer who can balance high-level architectural design in AWS with low-level backend coding in Go. You will bridge the gap between infrastructure and application code. You will find and implement opportunities to increase every developer’s leverage.
What you'll do... Architect "golden paths” You will build and maintain the core shared libraries, SDKs, and code-generation tools (gRPC, OpenAPI) that power our entire engineering organization. Our goal is to abstract away complexity so product teams can ship features faster and safer. Design and optimize cloud infrastructure You will take ownership of our AWS ecosystem (ECS, RDS, MSK, etc.). You will design capable architectures on a whiteboard and are comfortable getting your hands dirty debugging production performance, tuning database parameters, and automating toil. Treat the platform as the product You will embed with product teams to understand their friction points, treating them as your customers. You will champion a philosophy where we build tools that are intuitive and helpful. Elevate observability You will set the standard for how we observe and debug our systems. This involves going deep into the stack to debug distributed system failures, improving our alerting strategy to reduce noise, and teaching the wider engineering team how to troubleshoot effectively. Be a mentor and technical leader You will also drive technical standards across the company by documenting patterns, writing clear guides, presenting to all engineers, and mentoring engineers on best practices. Ideal Candidate Profile Deep expertise in backend programming You have significant experience building high-performance backend services or libraries. You understand the nuances of the language and how to write code that others find easy to read and import. Cloud fluency You have architected and managed production workloads on AWS or other clouds. You know your way around ECS, RDS, Lambda and data streaming services, and you understand the trade-offs between cost, performance, and complexity. A DevEx mindset You have a history of building tools that make developers' lives easier. You understand that documentation is a feature, and you take pride in writing clear, accessible guides for your tools.
