## Description

Toast is a rapidly growing company that's revolutionizing how the restaurant industry does business by pairing technology with an extraordinary commitment to customer success.

We're looking for a Senior Software Engineer with strong experience building and operating distributed systems to join the team that connects Toast's customers, services, and infrastructure.

A day in the life (Responsibilities)

- Design, build, test, deploy, and operate software that helps Toast's services connect and route traffic reliably.

- Improve the scalability, resilience, and observability of critical systems as Toast grows.

- Take end-to-end ownership of systems, making changes safer to roll out and failures easier to detect, diagnose, and resolve.

- Investigate production issues, participate in on-call, and turn what we learn into lasting improvements.

- Collaborate with engineers across Toast on projects that span services and infrastructure.

- Contribute to technical designs and raise team standards through thoughtful code reviews and technical discussions.

- Mentor and provide technical guidance to other team members.

- Use AI tooling as a genuine part of your workflow, not an afterthought.

What you'll need to thrive (Requirements)

- 5+ years of back-end software engineering experience in Kotlin or another relevant language.

- Strong experience with distributed systems, including designing for reliability, diagnosing failures, and scaling services.

- Experience owning and operating production systems, with solid instincts around testing and code quality.

- A track record of tackling ambiguous, high-impact challenges and delivering scalable solutions.

- Curiosity about how traffic moves through large-scale systems, and the motivation to learn quickly and apply what you learn.

- Clear communication and a collaborative approach to working across teams and time zones.

What will help you stand out (Nonessential Skills/Nice to Haves)

- Experience building platforms or infrastructure used by other engineering teams.

- Familiarity with network or traffic-management concepts such as routing, load balancing, DNS, or HTTP.

- Experience with AWS, infrastructure as code (such as Terraform), or cloud networking.

- Experience with service meshes (such as Envoy or Istio) or operating high-availability traffic systems.

Our Tech Stack

- Backend services written primarily in Kotlin

- A service mesh with an xDS control plane for service-to-service traffic

- AWS networking, including VPCs, transit gateways, and load balancers

- Terraform and Atlantis for infrastructure as code

- Cloudflare for edge routing and DNS

- AI-assisted development tools as part of daily engineering
