Overview

We think standard apps like email and notes are due for a serious upgrade. At Bjak, our A1 team is building a proactive smart assistant designed to handle everyday conversations, errands, and complex workflows with minimal prompting. We want to shave hours off routine tasks by creating an experience that feels genuinely intelligent. As a Backend Engineer focused on AI Agent Systems, you will own the inference and orchestration layer sitting right between powerful models and our users. If you love wrestling with non-deterministic behavior, reducing latency, and building rock-solid APIs that actually work in the real world, this fully remote, worldwide opportunity is waiting for you.

Key Responsibilities

Build and operate scalable backend systems that serve AI-powered features directly in production.
Design resilient inference pipelines and orchestration layers that can handle multi-step reasoning.
Ensure high reliability for long-running workflows despite the unpredictable nature of underlying models.
Integrate external tools seamlessly while keeping latency and operational costs low.
Provide stable, highly observable APIs used by our mobile and desktop clients every single day.

Requirements

Proven software engineering experience building and scaling production backend systems.
Strong background in working with LLMs, inference pipelines, or agentic orchestration frameworks.
Deep understanding of how to manage latency, rate limits, and non-deterministic model outputs.
Comfort writing clean, maintainable code in modern backend languages and environments.
A passion for solving hard distributed systems problems and creating delightful user experiences.

What You'll Gain

The freedom to work from anywhere in the world on a fully remote team.
Direct ownership over core AI architecture that impacts thousands of daily interactions.
A collaborative culture that values fast iteration, bold ideas, and high engineering standards.
Competitive compensation and the chance to shape the future of proactive computing.
