Senior Site Reliability Engineer (SRE

About
January

At
January, we’re transforming the lives of borrowers by bringing humanity to
consumer finance. Our data -driven products empower financial institutions to
streamline collections and help borrowers regain financial stability and
control over their lives. We’re not just expanding access to credit — we’re
restoring dignity and paving the way for millions to achieve financial freedom.

About
the Role

As a Senior
Site Reliability Engineer (SRE), you will establish SRE practices from the
ground up — ensuring reliability, scalability, and performance as January
scales from thousands to millions of borrowers. You’ll architect resilient
infrastructure, design modern observability solutions, and build sustainable
on -call processes that evolve with our rapid growth.

Your work
will directly address scaling challenges including database optimization, async
workflow infrastructure, and data pipeline reliability — enabling the
engineering team to ship confidently and efficiently.

Key
Responsibilities

• Lead incident response and develop
  sustainable on -call practices, including runbooks, blameless postmortems,
  and continuous improvement to reduce MTTR.
  
• Build and maintain self -service observability tools
  (Datadog, Prometheus, ELK) for proactive monitoring and troubleshooting.
  
• Create and maintain Infrastructure as Code (IaC) using Terraform or CloudFormation for consistent, secure
  AWS environments.
  
• Partner with development teams to architect
  resilient, scalable infrastructure for critical components like
  databases, networking, async workflows, and data pipelines.
  
• Design and implement robust CI/CD pipelines (GitHub
  Actions) with advanced deployment strategies (blue/green, canary).
  
• Drive best practices in reliability and
  performance early in the design phase to future -proof January’s systems.
  

Required
Skills & Experience

• Proven experience leading incident response and
  postmortem processes for high -availability production systems.
  
• Deep expertise in designing highly available
  architectures (EC2, Fargate, auto -scaling, health checks,
  graceful degradation).
  
• Strong experience with AWS cloud infrastructure and IaC tools (Terraform, CloudFormation).
  
• Hands -on experience with CI/CD automation using GitHub Actions or equivalent tools.
  
• Proficiency in observability and monitoring stacks (Datadog,
  Prometheus, ELK).
  
• Solid scripting/programming skills in Python (for
  automation, tooling, and debugging).
  
• Excellent communication and documentation skills, with
  the ability to collaborate across engineering and platform teams.
