What you'll do
- Design and develop the core services, APIs, and infrastructure that enable AI agents to plan, execute, and collaborate on complex software engineering tasks
- Build systems that coordinate multiple specialized agents, manage dependencies, schedule work, and support long-running, asynchronous workflows
- Develop secure, stateful execution environments that manage agent lifecycles, context, tool invocations, retries, recovery, and execution isolation
- Implement sandboxing, fine-grained permissions, and security boundaries that allow agents to interact with code, tools, and internal systems without compromising security
- Integrate LLMs, development workflows, internal APIs, and external tools through secure, extensible interfaces and emerging standards such as MCP and A2A
- Help create systems where engineers can guide, supervise, and collaborate with autonomous agents, maintaining control over important decisions
- Evaluate emerging technologies, challenge existing approaches, experiment with new architectural patterns, and help define how autonomous software engineering evolves at Signicat
- Apply understanding of distributed systems, concurrency, fault tolerance, and software architecture to challenges that don't always have established solutions
What we're looking for
- Strong software engineering experience, ideally with Go, building robust backend services, APIs, and distributed systems
- Comfortable working with Kubernetes, containers, and cloud-native infrastructure, ideally on Google Cloud Platform
- Understands how to design systems that handle concurrency, failures, asynchronous execution, and complex state transitions
- Cares about clean architecture, well-designed APIs, maintainable code, and automated testing
- Understands the importance of security, particularly around authentication, authorization, isolation, and executing untrusted workloads
- Curious about LLMs and autonomous agents, including tool calling, context management, multi-agent collaboration, and agent orchestration
- Enjoys exploring emerging technologies, experimenting with new approaches, and turning promising ideas into practical solutions
- Comfortable navigating ambiguity, taking ownership of challenging technical problems, and helping shape architectural decisions
- Enjoys sharing knowledge, collaborating with others, and challenging assumptions to find better solutions
Nice to have
- Built systems using agent frameworks such as Google ADK, or worked with protocols like MCP or A2A
- Experience with sandboxing or workload isolation technologies such as gVisor, WebAssembly, or container-based execution environments
- Worked with event-driven architectures, workflow engines, distributed schedulers, or systems supporting long-running processes
- Experimented with AI coding agents, autonomous development workflows, or multi-agent systems
- Experience designing secure integrations with external services, including OAuth and delegated authorization
- Explored graph-based architectures, RDF, SPARQL, or event-driven systems
