Department Overview
The AI Engineering team builds secure, reliable, and reusable AI capabilities for HEDGESERV’s business and technology platforms, partnering across engineering, security, data, and operations to move solutions into production.
We integrate AI into existing workflows and platforms, focusing on measurable outcomes, production discipline, responsible AI, security, human oversight, and evidence-based evaluation.
Role Overview
You will design, build, and operate production AI agents for financial operations and enterprise workflows. In this role, the AI harness is the production layer around the model: the agent runtime, orchestration, controls, evaluation, and observability. You will help shape and evolve this layer, including retrieval, memory, tool execution, workflow state, human approvals, and safety controls.
You will bring software engineering expertise, hands-on production LLM experience, sound architectural judgment, effective troubleshooting skills, and a collaborative approach to working across teams. You will also contribute to establishing reusable patterns and standards for HEDGESERV engineering teams.
Key ResponsibilitiesRuntime
Design, deploy, and support reliable production runtimes for AI agents serving financial operations and enterprise workflows.
Orchestration
Build and extend agent loops, including context assembly, retrieval, memory, tool selection, execution limits, workflow state, and response validation.
Controls
Implement authorization, human approvals, policy checks, validation, checkpoints, idempotency, retries, and exception handling throughout agent workflows.
Enterprise Integration
Build validated and auditable tool and system interfaces with least-privilege permissions, prompt-injection defenses, and controls outside the model that isolate reasoning from deterministic execution.
Evaluation
Build repeatable tests and regression suites for agent outcomes, supporting evidence, and tool-execution paths; diagnose quality, safety, failures, latency, and cost.
Observability
Monitor and troubleshoot production agents, maintain audit evidence, and translate operational findings into reusable engineering standards and best practices.
Required Qualifications
Bachelor's degree in Computer Science, Engineering, Information Technology, or a related technical field, or equivalent practical experience.
Demonstrated software engineering experience, typically gained over 5+ years, including experience delivering LLM- or agent-based applications in production environments.
Proven experience with Python, API design, asynchronous processing, automated testing, source control, and AWS engineering; experience with a managed model platform such as Amazon Bedrock or an equivalent service.
Hands-on experience implementing agent loops, context assembly, retrieval, memory, tool selection and limits, durable state, checkpoints, retries, and idempotency.
Experience building regression evaluations for outcomes, supporting evidence, and tool-execution paths, along with implementing secure access controls, prompt-injection defenses, and deterministic operational safeguards.
Demonstrated troubleshooting, analytical, communication, and cross-functional collaboration skills.
Preferred Experience
Experience in financial services or another regulated or highly controlled environment.
Experience with model or tool gateways and interoperability protocols, such as MCP, as well as multi-agent systems and durable workflow engines.
Knowledge of secure tool execution, containers, infrastructure as code, CI/CD, and observability platforms.
Familiarity with responsible AI practices, governance frameworks, model risk management, and regulatory controls.
Experience contributing to shared AI platforms, mentoring engineers, or establishing reusable engineering standards.
Relevant certifications in AWS, cloud engineering, AI, security, or data are valued but not required.
Benefits
Attractive compensation package including extensive set of benefits, such as platinum health insurance, sport membership, food vouchers, employee assistance program, etc.
25 vacation days per year.
Additional vacation days with 1 added for every year in the company (up to 3 additional days).
Flexibility in working hours and locations (WFH available).
Professional environment with great development opportunities.
Тuition reimbursement program (personal budget up to 1000 EUR).
Enjoy a start-up like environment on the back of a well-established and profitable company.
Work in a culture that rewards results.
Be free to make many of your own decisions.
