Software Engineer - Agent To Agent/A2A

Software Engineer - AI - A2A - Remote - Contract - 6 months, renewable

We are seeking a skilled and motivated Software Engineer with a deep understanding of agent-based protocol implementations and secure communication systems. The ideal candidate has hands-on experience with Message Communication Protocols (MCP), Agent-to-Agent (A2A) and is proficient in Python and JavaScript.

You will collaborate across engineering, security, and architecture teams to build secure, scalable, and interoperable agent protocols that drive our identity and access management platforms and decentralised communication systems.

Responsibilities:

• Design, develop, and maintain agent protocol implementations (eg, A2A communication, MCP).
• Build and integrate services using JSON-RPC 2.0 and similar lightweight messaging protocols.
• Implement and maintain OAuth 2.0 flows to support secure authorization and delegation.
• Collaborate with IAM teams to manage IAM roles, policies, and least-privilege access across systems.
• Develop reusable modules and SDKs in Python and JavaScript for internal and external integrations.
• Contribute to security-first system designs in alignment with modern identity and access management practices.
• Write clean, maintainable, and well-documented code.
• Participate in code reviews, sprint planning, and architectural discussions.

Required Skills and Qualifications:

• Strong experience with agent protocol design and implementation (eg, MCP, A2A).
• Proficiency in Python and JavaScript development.
• Deep knowledge of JSON-RPC 2.0 and its application in distributed systems.
• Experience implementing and managing OAuth 2.0 authorisation flows.
• Familiarity with IAM roles, permissions, and policy configurations in cloud environments (eg, AWS IAM).
• Solid understanding of secure communication practices and authentication protocols.
• Ability to troubleshoot and debug complex protocol and integration issues.

Preferred Qualifications:

• Experience working with decentralised identity frameworks or verifiable credentials.
• Familiarity with cloud-native services and architectures (eg, AWS, GCP).
• Prior contributions to open-source agent frameworks or protocol libraries.
• Understanding of event-driven or message-based architectures (eg, Kafka, MQTT).
