Key Responsibilities

• Develop and sustain cloud infrastructure and standardized paths facilitating resilience, security, and scalability by default.
• Empower teams with self-serve observability tools encompassing monitoring, alerting, logging, tracing, and automation of provisioning and deployments.
• Streamline incident response through tailored tooling, up-to-date runbooks, and conducting thorough post-incident reviews leading to improvements.
• Define identity and least-privilege frameworks for non-human actors such as agents and CI systems, ensuring access with minimal risk.
• Create clear infrastructure and operational documentation compatible with both humans and automated agents.
• Establish standards for safe releases by embedding guardrails and pipeline checks rather than gatekeeping procedures.
• Provide transparency and control over cloud and inference-related expenditures to allow cost management.
• Coach engineering teams on reliable operational practices and collaborate with Engineering and Product teams to balance new features with platform stability.

Required Qualifications and Attributes

• Proven experience leading incident command during live production issues and managing platforms through significant growth phases.
• Advanced capabilities in infrastructure management including Infrastructure as Code (Terraform, Terragrunt, CDK), containers (ECS), cloud platforms (preferably AWS), CI/CD pipelines, and scripting languages such as Python, TypeScript, or Bash.
• Expertise with observability tools like Datadog or equivalents, understanding distributed tracing, structured logging, and incident management principles.
• A strong security focus, especially with networking, cloud architecture, and the security challenges of agentic systems, including secure credential handling and least privilege enforcement.
• Experience utilizing coding agents in workflows (e.g., Claude Code), with informed perspectives on their applications and limitations.
• Ability to navigate complex technical environments with a focus on business outcomes, effectively communicating system health and risks to diverse audiences.
• A collaborative and kind team player attitude.
• Bonus: Enthusiasm for marketing, design, and delivering outstanding user experiences.

Technology Stack

We utilize technologies including AWS, ECS, Terraform, Terragrunt, GitHub Actions, Datadog, Claude Code, Linear, Notion, Postgres, DynamoDB, and Snowflake.

Benefits include competitive salary reviewed biannually, Employee Share Option Program (ESOP), generous health and wellness perks including annual wellness bonus, premium EAP access, six weeks paid annual leave, comprehensive parental leave policies, a personal learning and development budget, plus flexible work arrangements favoring office presence but accommodating work-from-home as needed. On joining, you also receive a personalized Tracksuit kit reflecting our energetic and practical style.
