Senior Software Engineer, AI DevEx

Accountabilities

• AI-Powered Developer Platform: Design and build the infrastructure that enables AI agents to participate in software development, from initial task intake through implementation, testing, and pull request review.

• Development Environments: Build and maintain reproducible local development stacks and cloud-based coding environments that allow engineers and agents to run services and tests reliably without extensive manual setup.

• Autonomous Coding Agents: Integrate and orchestrate AI agents that transform tickets, bug reports, and other requests into validated code changes and review-ready pull requests, including browser and native application testing where appropriate.

• Agent Selection and Orchestration: Evaluate, select, and integrate open-source and commercial coding agents. Configure triggers, credentials, contextual information, tools, and execution workflows to ensure agents operate effectively and efficiently.

• Workflow Integrations: Connect agent workflows to tools and systems such as Slack, Jira, GitHub, Datadog, and incident management platforms, enabling production alerts and operational issues to initiate potential fixes.

• Infrastructure and Automation: Develop and improve cloud infrastructure, containers, CI/CD pipelines, and infrastructure-as-code solutions to support reliable, scalable, and repeatable agent execution.

• Security and Governance: Establish guardrails governing agent access to data, secrets, and personally identifiable information. Define appropriate permissions, compliance controls, and human-review requirements for a regulated, real-money contest environment.

• Continuous Improvement: Identify recurring issues that limit agent effectiveness, including missing context, unreliable tests, insufficient tools, and environment gaps, then address their root causes.

• Agent Evaluation and Observability: Measure agent performance across coding and non-coding tasks, track execution quality and costs, and use telemetry and evaluation results to improve reliability and efficiency.

• Business-Wide Enablement: Develop reusable agent runtimes, triggers, and safeguards that can support teams beyond engineering, helping other functions adopt automation with appropriate guidance.

• Performance Measurement: Improve key indicators such as pull request cycle time, review latency, and the proportion of pull requests authored or reviewed by AI agents.

• Cross-Team Collaboration: Work independently while communicating clearly across distributed teams, sharing progress, proactively identifying opportunities, and helping establish effective practices for AI-assisted development.

Requirements

• Professional Experience: At least six years of software engineering experience, including meaningful work in infrastructure, platform engineering, developer experience, or internal tooling.

• Advanced AI Agent Usage: Current, hands-on experience using AI coding agents such as Claude Code, Codex, Cursor, or similar tools for at least 90% of your development work. You should understand their limitations and know how to improve their results.

• Multi-Agent Orchestration: Experience coordinating multiple agents or delegating work to subagents is highly desirable, particularly when supported by custom skills, hooks, harness configurations, or parallel execution workflows.

• Cloud Infrastructure: Strong experience with AWS services and infrastructure, including ECS/Fargate, RDS, Lambda, networking, and IAM.

• Infrastructure as Code and Delivery: Practical experience with Terraform, AWS CDK, CloudFormation, or comparable infrastructure-as-code tools, along with containers and CI/CD pipelines that you have built, maintained, or optimized.

• Software Development Skills: Ability to contribute directly to TypeScript and Node.js services and work comfortably within existing codebases.

• Developer Tooling: Experience building internal platforms, development environments, automation systems, or other engineering tools that achieve real adoption among developers.

• Data-Driven Evaluation: Familiarity with assessing AI agents across coding and non-coding tasks, interpreting performance data, and using repeatable evaluations to guide technical decisions.

• Autonomy and Initiative: Ability to identify problems independently, move quickly from experimentation to implementation, and proactively improve engineering workflows.

• Remote Collaboration: Strong written communication skills and the ability to keep colleagues informed while collaborating across US and Prague time zones.

• Preferred Environment Expertise: Experience with sandboxed or ephemeral development environments using Docker, devcontainers, Kubernetes, Nix, or similar technologies.

• Preferred Agent Integrations: Experience building Model Context Protocol (MCP) servers or other integrations that enable AI agents to interact securely with real systems and tools.

• Preferred Observability Skills: Familiarity with OpenTelemetry, LLM tracing, agent execution telemetry, evaluation frameworks, and cost tracking.

• Industry Experience: Experience in a regulated industry, such as gaming or financial technology, is an advantage.

• Additional Interest: An enthusiasm for sports is a plus.
