Tiebreak's Careers

About Tiebreak Solutions

Tiebreak is a global software and infrastructure company behind a high-performance trading platform and a marketing/CRM platform. We’re in the middle of a significant transition — consolidating and modernizing our system(s), and this is a unique opportunity to genuinely influence how it gets built.

We are hiring an AI engineer — Sofia or Israel.

We have AI agents doing real work against production codebases today: they take a work item, plan it, write the code, review it, and open a pull request for a human to approve. What that system does not have is anyone whose job is to make it measurable.

Responsibilities:

• Building the agents — new ones, and extending the ones already running.
• Their tools, and the context architecture that decides how each agent behaves.
• The evaluation harness that catches an agent getting worse before the change merges.
• The telemetry that proves what any of it is actually worth.
• Budgets that govern model spend instead of observing it.
• The retrieval layer that lets an agent find what it needs instead of reading an entire repository to answer one question.
• The runtime underneath is moving from self-managed Kubernetes to Bedrock AgentCore, you will own the second half of that migration.

Requirements/Tools:

Experience with the following:

• Python – used across the service and agent codebases.
• Temporal – used for orchestration — multi-stage pipelines that run for hours with human approval gates in the middle.
• LangGraph and Claude Code (agent runtimes).
• AWS Bedrock – for models behind a LiteLLM gateway that keeps provider choice open.
• Langfuse – used for LLM traces and evaluation.
• OpenTelemetry with Prometheus and Grafana for everything else.
• PostgreSQL with pgvector used for memory and caching.
• MCP servers for tools.
• Azure DevOps Repos and Pipelines for delivery.
• Experience in startup environments would be considered an advantage
