    About the Role

    We’re looking for a backend-focused software engineer who treats quality as part of engineering, not as a separate function.

    This is not a QA-only or SDET role. You will write production backend code, design APIs, and take ownership of testing, reliability, and correctness across the systems you build.

    Our platform is data-heavy and API-driven, so correctness, observability, and thoughtful testing matter as much as feature delivery.

     

    What You’ll Do

    • Build and maintain backend services and APIs
    • Design and implement meaningful tests (unit, integration, contract)
    • Validate data integrity and API contracts before production
    • Integrate tests into CI/CD pipelines
    • Monitor production behavior and test outcomes
    • Collaborate with engineers, product, and data teams to ship reliable systems
    • Use AI tools responsibly to accelerate work (not replace understanding)

    What We’re Looking For

    • Strong backend engineering experience
    • Comfortable owning both code and tests
    • Solid understanding of REST APIs and data flows
    • Experience with CI/CD and cloud environments
    • Ability to reason about failure modes, edge cases, and trade-offs
    • Clear communicator who can explain technical decisions

    • Senior Platform & Infrastructure Engineer
    • This role is a software-first approach to systems. You aren't just managing servers; you are building the platform that runs the company. It requires a blend of high-level architectural thinking and deep-tier systems automation.

       
    • The Core Identity
    • Software-First Infra: You treat infrastructure like a product, using software engineering principles (code reviews, testing, CI/CD) to manage the cloud.
    • Developer Enablement: You build self-service tooling so product engineers can deploy and scale their own services safely.
    • Architectural Guard: You own the long-term reliability and performance strategy, ensuring the system scales as the business grows.

       
    • The Technical Stack
    • Category
    • Core Technologies
    • Cloud Platform
    • AWS or GCP (Identity, IAM, VPCs, Managed Services)
    • Orchestration
    • Kubernetes (Deep internals: CRDs, Operators, Networking, ingress)
    • Languages
    • Go or Python (for automation); TypeScript/Node (for tooling/CDK)
    • IaC
    • Terraform (Primary) or Pulumi
    • Data & Storage
    • PostgreSQL (Performance tuning, replication, schema evolution)
    • Observability
    • Prometheus, Grafana, Datadog (Tracing, SLIs, Alerting)
    • CI/CD
    • GitHub Actions, ArgoCD, or CircleCI

       
    • What This Is vs. Is Not
    • ✅ IS: Designing a Kubernetes operator to automate database migrations.
    • ❌ NOT: Manually clicking in the AWS Console to resize a disk.

       
    • ✅ IS: Improving developer velocity by building a "one-command" staging environment.
    • ❌ NOT: Being the "gatekeeper" who must approve every deployment ticket.

       
    • The Ideal Candidate Profile
    • 5+ Years in Software or Systems Engineering with a focus on cloud-native platforms.
    • Operator Mindset: You've run high-traffic systems and know how they break at 3 AM (and how to design them so they don't).
    • Tool Builder: You prefer writing a Go service to automate a task rather than writing a documentation page on how to do it manually.
    • Would you like me to help you map your specific experience with these tools (K8s, Terraform, Postgres) into a cohesive interview narrative?
