About Kintsugi
Kintsugi is revolutionizing sales tax automation with our AI-powered platform designed specifically for e-commerce and SaaS businesses. Our solution reduces tax preparation time by 75 percent and cuts compliance costs by 50 percent, allowing finance teams to focus on strategic initiatives rather than routine calculations. As we continue to grow and disrupt the tax automation space, we're building a world-class team to help us scale with purpose.
The Role
We're looking for a Senior Site Reliability Engineer (DevOps) to help scale and harden the infrastructure that powers Kintsugi. This role sits at the intersection of software engineering and operations: you'll keep production reliable under real load, and you'll build the tooling and automation that reduce the manual work of doing that, rather than absorbing more of it yourself as we grow.
You'll work closely with Platform Engineering, Product, and QA to design resilient architectures, improve deployment pipelines, and build the internal tools and guardrails that let the team move quickly without sacrificing stability. You'll operate across our managed Kubernetes and AWS-hosted data layer (Postgres, Redis, networking), and you'll be a key force in shaping the reliability and developer-experience foundation of our engineering org.
We're an agentic-coding-first team — coding agents already do real engineering and operations work here, not just autocomplete on the side. We expect this role to build and extend that practice, not just adopt it.
What You'll Do
Own the reliability of production infrastructure running on managed Kubernetes and AWS, keeping a high-traffic system up and catching issues before customers do
Work agent-first day to day: build, debug, and automate using agentic coding workflows as your default mode, not a fallback tool
Build internal tools and automation that eliminate recurring manual work (toil) for the team, rather than just documenting runbooks around it
Develop and operate monitoring, alerting, and observability systems (metrics, tracing, logging) across the stack
Partner with engineering teams to design for reliability and performance from the start, not bolt it on after incidents
Automate infrastructure management through infrastructure-as-code, and improve CI/CD pipelines and local developer workflows
Lead and evolve incident response practices, including postmortems and blameless learning
Optimize infrastructure for cost efficiency while maintaining high availability and security standards
Contribute to security, compliance, and disaster recovery efforts as the platform scales
Support developer enablement: build and improve the in-house tooling, local dev workflows, and internal platforms other engineers rely on
What We're Looking For
5-8 years in Site Reliability Engineering, DevOps, or Infrastructure Engineering roles, with real ownership of a production system at meaningful scale — someone who drives reliability and tooling initiatives rather than waiting to be assigned them
Fluent working agent-first day to day — directing coding agents to do real engineering work, not just occasional autocomplete
Strong foundation in AWS-hosted data and networking services (RDS/Postgres, ElastiCache/Redis, VPC/networking) and experience running workloads on managed Kubernetes
A track record of building tools, not just running playbooks: scripts, services, or internal platforms that removed manual work for a team
Hands-on experience with CI/CD pipelines and infrastructure-as-code (e.g., Terraform, CloudFormation)
Expertise in observability stacks (metrics, tracing, logging) and modern monitoring practices
Familiarity with security and compliance in cloud environments (SOC 2, GDPR, etc. a plus)
A collaborative mindset with a passion for empowering developers to move fast safely
Experience with (or strong interest in) developer enablement — building the internal tooling and platforms that make other engineers more productive
Nice to have: experience operating across multiple cloud providers, as our infrastructure footprint expands
