Requirements

8+ years of production software engineering experience, with strong C#/.NET expertise, solid React skills, and a strong foundation in software engineering principles.
Deep expertise in distributed systems, including microservices, messaging, consistency trade-offs, and diagnosing failures in high-load environments.
Experience working with SQL databases, non-relational data stores, cloud platforms, containerized deployments, and event-driven or streaming architectures at scale.
Regular use of AI coding agents within production codebases, coupled with accountability for the correctness, security, and maintainability of delivered software.
Proven ability to expose capabilities to AI systems through tool and function interfaces, structured APIs, MCP servers, or similar model-facing integration patterns.
Strong understanding of common AI model failure modes, including hallucinations, context degradation, prompt injection, non-determinism, and silent regressions, along with effective mitigation strategies.
Critical evaluation of generated code at scale, with the ability to identify and reject plausible but unsafe outputs while leveraging tests, evaluations, and architectural context to ensure reliability.
Excellent English communication skills, a collaborative mindset for working with teams across EMEA, and a strong interest in shaping AI-native engineering practices.

Responsibilities

Design and build scalable .NET services and React frontends across Web Shell, Agentic Ecosystem, and Endpoint Observability domains.
Build event, telemetry, and audit pipelines covering ingestion, correlation, retention, export, and access control at enterprise scale.
Expose platform capabilities safely to Tia and third-party agents through MCP tools, typed APIs, and tenancy-aware authorization.
Deliver production features in a microservices codebase using AI coding agents, contract tests, schema validation, and integration coverage.
Debug distributed, partly model-driven systems and build the tracing needed to understand non-deterministic behavior.
Maintain service-layer context for agents, including API contracts, domain vocabulary, architectural decision records, and repository instructions.
