<div></div>
<div>The Mission</div>
<div></div>
<div>We are looking for a Senior Backend Engineer to own the &quot;brain&quot; of our application. This is a heavy-coding, high-impact role where performance is the baseline. You will be responsible for architecting and building high-performance compute engines, translating complex business logic into lightning-fast, memory-safe Rust services. 
If you are a builder who believes that &quot;if it's worth doing twice, it's worth automating,&quot; and you have a deep appreciation for the elegance of the Rust borrow checker, we want to talk to you. 
 
What You'll Do</div>
<ul><li>Build the Core: Develop and maintain mission-critical business logic using Rust and the Tokio runtime, deployed primarily via high-performance Lambda functions.</li>
<li>Architect Infrastructure: Take full ownership of your stack using Terraform. You'll provision and manage everything from DynamoDB schemas to API Gateways and event-driven pipelines.</li>
<li>Optimize &amp; Profile: This isn't just &quot;functional&quot; code. You will profile memory usage and execution timing to shave off milliseconds and minimize compute overhead.</li>
<li>Define the Interface: Design and implement robust REST APIs that serve as the bridge between our complex backend logic and the frontend.</li>
<li>Cultivate Excellence: Set the bar for Rust within the team. You'll establish coding standards, mentor others, and conduct rigorous code reviews to ensure our &quot;brain&quot; remains healthy and scalable.</li>
</ul><div>Technical Profile</div>
<ul><li>Rust Mastery: You have deep experience with ownership, lifetimes, and asynchronous programming in Rust. You know your way around the ecosystem (Serde, Axum/Tower, etc.).</li>
<li>Serverless Native: You understand the nuances of event-driven architecture. You know how to work within (and around) the constraints of serverless environments.</li>
<li>Automation First: You have a &quot;script-first&quot; mentality. Experience with IaC (Terraform) is highly recommended.</li>
<li>Data &amp; Observability: You've managed NoSQL databases (DynamoDB) and have a disciplined approach to observability using tools like CloudWatch and CloudTrail.</li>
<li>Testing Discipline: You view unit and integration tests as a core part of the feature, not an afterthought.</li>
</ul><div>Our Tech Stack</div>
<ul><li>Languages: Rust (Async/Tokio)</li>
<li>Infrastructure: AWS (Lambda, SQS, SNS, API Gateway, DynamoDB)</li>
