Senior Software Engineer - Backend (Rust)

You'll own backend features from the initial product requirement through design, implementation, testing, deployment, and production support.

A typical project might start with a request to integrate Key Insight with a new cloud provider or enterprise technology. Rather than simply receiving an implementation specification, you'll investigate the technology yourself: understand its APIs and SDKs, experiment with how they work, determine how our product should integrate with them, and recommend an approach to the team.

From there, you'll translate that research into a technical design, identify any architectural changes required, break the work into executable pieces, and implement the solution.

You'll also:

Design and build backend services in Rust , including REST APIs, data models, database schemas, and service-to-service integrations.

Build integrations with cloud and enterprise platforms , researching unfamiliar APIs, SDKs, services, and technologies when necessary.

Own technical design for new capabilities , considering architecture, scalability, performance, reliability, security, and maintainability.

Scale a growing product. As adoption increases, you'll identify and solve performance bottlenecks, scalability challenges, and architectural limitations.

Take features through production , including implementation, unit and integration testing, CI/CD, deployment, validation, performance testing, and production readiness.

Debug complex production issues across application, integration, database, and infrastructure layers and make the changes necessary to resolve them.

Partner closely with Product and Engineering to refine requirements, evaluate technical trade-offs, and turn product needs into well-designed engineering solutions.

Support customers and internal teams when complex technical issues arise, helping diagnose problems and improve the product based on what we learn.

Collaborate with engineers across a globally distributed team , participating in design reviews, code reviews, technical discussions, and architectural decisions.

8+ years of professional software engineering experience , with significant experience in backend development.

Strong hands-on programming experience in Rust, C++, or Go . Production Rust experience is preferred.

Designing and building backend services and microservices used in production.

Designing and implementing REST APIs , including API contracts, integrations, and service-to-service communication.

Designing database schemas and data models and working with application data-access layers.

Building or integrating with third-party APIs, SDKs, cloud services, or enterprise platforms .

Taking ambiguous technical requirements, researching unfamiliar technologies, and turning findings into a practical technical design and implementation plan .

Diagnosing and solving performance and scalability problems in production backend systems.

Debugging complex issues across multiple components or services.

Owning software through the full development lifecycle: design, implementation, testing, deployment, production validation, and ongoing support .

Working effectively with Product Management and other engineering teams in a distributed environment.

Experience with any of the following will help you ramp quickly:

Production development in Rust

Kubernetes , containers, or cloud-native deployment environments

AWS, Azure, GCP, OCI, Alibaba Cloud, or other cloud platforms

Building products that integrate with multiple external systems or cloud providers

Cybersecurity, cryptography, key management, certificate management, or observability products

Experience working on a product during a high-growth or adoption phase , particularly where increasing usage created new performance or scalability challenges

The strongest engineer for this team isn't simply someone who knows Rust syntax.

We're looking for someone who can be given a problem and independently figure out how the technology works, evaluate the available APIs and SDKs, propose an architecture, build the integration, test it at scale, deploy it, and help troubleshoot it once customers begin using it.

If you enjoy that combination of research, backend architecture, hands-on coding, integrations, and production problem-solving , this role should give you substantial technical ownership.
