Kato | Senior Software Engineer | San Francisco, CA | ONSITE | Full-time

Kato is building a compliance-first AI servicing platform for the $24B lending market. While others treat regulatory guardrails as an afterthought, we’ve built a regulatory rules system with an AI decision engine on top. Our first product is a Voice AI agent currently handling loan servicing calls for major fintechs like Bilt Rewards and Parafin.

We are backed by Pear VC and angels from Brex, Bridge, and Square. You’ll be our second engineering hire, working directly with our CTO (ex-Google/Brex EM) and CEO (ex-Goldman/Brex).

The Role: As an early hire, you’ll own mission-critical projects across the entire stack. You’ll lead the architecture of our real-time voice processing system, optimize LLM integrations for compliance-aware conversations, and build out our customer-facing dashboards.

Tech Stack:

Backend: Golang, PostgreSQL

Frontend: Next.js, TypeScript, React, Tailwind

Infra: AWS, Terraform, Kubernetes, Docker

AI/ML: LLMs, Speech-to-Text, Text-to-Speech

Requirements:

2-5 years of production software experience.

Strong API design and architectural thinking.

An "owner's mindset"—we are a small, high-intensity team where everyone drives product direction.

Experience with WebRTC, real-time audio, or FinTech is a plus but not required.

Location: San Francisco (4 days/week in-person).

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering
