Role

Who you are

Experienced backend engineer comfortable with distributed systems and cloud platforms (AWS/GCP/Azure)
Skilled in Go or similar systems languages, and familiar with tools like gRPC, MongoDB, or Terraform
Curious about how AI, automation, and business ops fit together—and eager to learn more
Self-directed, proactive, and excited to work in a collaborative, low-bureaucracy environment

What the job involves

We’re looking for a Principal Engineer to help design and build the backend systems behind our AI automation platform. You’ll work across the stack, but with a strong backend focus, collaborating closely with peers and staying close to customer problems
This role sits at the intersection of AI, infrastructure, and product—ideal for someone who wants to build systems that actually run in production and solve messy real-world problems
We’re a small, experienced team with ambitious goals. If you’re excited to build meaningful systems that combine AI, operations, and modern backend engineering—this is a high-impact role with lots of ownership
Build and evolve scalable backend services in Go (with gRPC and MongoDB)
Work across AI workflows, automation logic, and third-party integrations
Contribute to system architecture and long-term tech decisions
Occasionally dive into TypeScript when needed
Collaborate directly with teammates and customers to shape solutions that work
Our Stack:
AI-driven products built on top of LLMs and orchestration layers
Go, gRPC, MongoDB, Terraform, Auth0
TypeScript, Next.js
Datadog for observability

Our take

Acai Travel is an AI-driven platform designed to optimize travel operations. Building on the success of their previous ventures, the founders aim to tackle inefficiencies that have worsened due to industry changes and the rising demand following the pandemic.

The platform aims to cut costs by up to half for agencies by automating routine tasks and boosting efficiency. Its approach provides agencies with insights into travel behavior, helping optimize services and predict upcoming trends.

Early results show a 20% reduction in handling times, with the potential for valuable savings as the full suite of products is rolled out. The company has already secured substantial funding and attracted clients like Kiwi.com and lastminute.com. Acai plans to invest in enhancing its platform and double agent efficiency.
