Senior Software Engineer, AI Team

Company overview

Avantos is building the industry’s first AI-native operating system for financial services
, redefining how firms onboard clients, deliver advice, and manage core servicing workflows. Our platform unifies fragmented data, automates complex processes, and embeds intelligent decision‑making across every step of the client lifecycle.

We partner with leading financial institutions and are scaling rapidly. We’re an execution‑driven, design‑obsessed, product‑led team composed of founders and leaders from Wharton, MIT, top design programs, and prior unicorn SaaS companies. We move fast, solve deep industry problems, and build technology that puts users back in control of their workflows.

If you love client impact
, product design
, complex problem solving
, and bringing AI‑enabled change to real‑world businesses
, Avantos is where you will thrive.

Over the course of your work, you could end up working on other backend systems as well. Some example projects include:

• Provisioning and evaluating models for a new AI feature using AWS Bedrock
• Building an end‑to‑end pipeline that ingests customer‑client interactions (e.g. call transcripts), and automatically kicks off workflows based on the contents

You will play a large part in shaping our AI tech stack. We’re looking for someone opinionated about AI tooling with an idea of what good looks like. The ideal candidate would have experience in the following:

• Prompt engineering
• Model evaluation and testing
• Building RAG‑based systems
• Data pipeline design
• Experience with containerization and orchestration (Docker, Kubernetes)
• Experience in the financial services industry
• Familiarity with microservices architecture

As noted above, we’re also looking for generalist backend skills. For the rest of the backend, we’re built with Go on top of Postgres. Our full backend tech stack includes the following - experience with these will be considered a plus, but not required:

• Languages
  :
  Go, Typescript
• Database: Postgresql
• AWS: ECS Fargate, App Flow, S3, SQS, Bedrock
• IaC: Terraform
• Observability: Datadog
