Mid–Senior Software Engineer, AI Agent Systems at Unbox

About the role

Unbox is seeking a Mid–Senior Software Engineer specialising in AI Agent Systems. The company wants an engineer who can use AI coding agents as part of a disciplined software development workflow, taking responsibility for the quality and reliability of the systems delivered.

This is not simply a role for someone who uses AI to generate code. You should be comfortable breaking down complex tasks, directing tools such as Codex, Antigravity and Claude, reviewing their output critically, testing the resulting software and resolving problems before deployment.

You will work across Python and TypeScript services, integrations and AI agent workflows. The position also requires practical knowledge of networking, cloud infrastructure and CI/CD pipelines to help you diagnose connectivity problems, troubleshoot deployments and maintain reliable software delivery processes.

Unbox emphasises independent thinking, self-motivation and comfort with uncertainty. The ideal candidate can learn unfamiliar systems quickly, take ownership of technical problems and deliver dependable software in a changing startup environment.

Responsibilities

• Build, develop and maintain production software using Python and TypeScript.
• Use AI coding agents such as Codex, Antigravity and Claude to accelerate development while maintaining engineering standards.
• Break down complex requirements into clear tasks that AI coding tools can execute effectively.
• Review AI-generated code critically, test its behaviour and resolve errors or failures.
• Develop and maintain APIs, integrations, backend services and AI agent workflows.
• Work with authentication systems, HTTP, networking and external services.
• Diagnose connectivity issues and troubleshoot application or deployment failures.
• Work with cloud infrastructure, containers, logs, secrets and CI/CD pipelines.
• Improve build, test and release processes to support reliable software deployment.
• Take ownership of features from implementation through deployment, monitoring and troubleshooting.
• Learn unfamiliar technologies and systems as project needs evolve.
• Apply sound engineering judgement to deliver maintainable, reliable software rather than relying on AI-generated code without adequate review.

Requirements

Applicants should demonstrate the following skills and experience:

• Strong professional experience building production software with Python and TypeScript.
• Practical experience using AI coding agents in a disciplined development workflow.
• Ability to define tasks clearly, review generated code, test functionality and troubleshoot failures.
• Working knowledge of APIs, authentication, HTTP and networking fundamentals.
• Familiarity with cloud deployments and infrastructure.
• Experience working with containers, logs, secrets and CI/CD pipelines.
• Ability to own a feature from development through deployment and operational troubleshooting.
• Strong problem-solving and technical decision-making skills.
• Clear communication and the ability to explain technical decisions.
• Ability to learn unfamiliar systems and technologies independently.
• A self-motivated, ownership-driven approach to software development.

Working style

Unbox is looking for someone who is comfortable working in a startup environment where requirements may change and solutions are not always obvious from the beginning.

The successful candidate should be willing to investigate problems independently, make progress without constant supervision, adapt to new information and take responsibility for the quality of the final product.

The company places greater emphasis on demonstrated engineering ability and dependable delivery than familiarity with any single AI agent framework.

Benefits

The hiring announcement does not specify a salary, employee benefits, formal working arrangements or a detailed professional development package.

The role offers the opportunity to work with AI coding agents and build AI-powered software systems across backend services, integrations and agent workflows.

Applicants should clarify the employment type, compensation, work location, remote-work policy and benefits directly with Unbox during recruitment.
