Technical Business Analyst Jobs in Illinois

INTRODUCTION

Leyton is an international consulting group with country business units across Europe (Italy, Spain, Germany, Poland, Sweden, France, the UK) and a centralized engineering team in Casablanca. We help thousands of clients capture value through specialized advisory work. We are now industrializing AI agents and automation as a core capability inside every country BU — and we are building the team that does it. The Transformation Office sits at group level and partners with each country business to ship automation that materially shifts the operating model. We hire one Business Systems Analyst & Developer per country. NOTE: This is a global opportunity, with positions available across multiple international locations!

ROLE AND RESPONSIBILITIES

This is a single-country role. You own one country's automation backlog end-to-end; you do not rotate, and you do not own work across countries. You sit inside one of Leyton's European country business units, next to the country leadership team. You walk each business line end-to-end with the responsible Business Partner or consultant, identify the workflow seams where a human can be substituted by an agent, and ship the automation. You prototype with Claude Code and the group platform stack (LLM agents, retrieval, MCP servers, n8n, internal APIs). PoCs in days. MVPs in two to six weeks. You hand each one to the Casablanca dev team for production and move to the next workflow. This is a first full-time role with real country-level ownership from week one. You will be paired with a senior peer and the Transformation Office, but the workflows you ship are yours — and they show up on the country P&L.

1. Embedded business discovery (Approximately 50%)
2. Sit next to the country BU leadership.
3. Shadow client visits, sales meetings, and internal ops sessions.
4. For each business line in scope, document the current process, identify the substitution seams, and translate ambiguous needs into shippable scope (PRD-light, success metrics, acceptance criteria).

5. Build and maintain the country automation backlog.

6. Build and hand off (Approximately 40%)

7. Prototype each workflow in Claude Code and the group stack.
8. Write the technical spec, runbook, and acceptance criteria.
9. Coordinate the handoff to the Casablanca dev team.
10. Stay on call for ~30 days post-handoff to defend design intent.

11. Re-use group-level patterns from peer-country teams; surface your own back to the group.

12. Coordination and cross-country (Approximately 10%)

13. Weekly sync with peer-country BSAs (Italy, Spain, Germany, Poland, Sweden, France, UK).
14. Monthly readout to the country CEO and the Transformation Office.
15. Maintain documentation so other countries can fork your work.

BASIC QUALIFICATIONS

- BA or BS in Data Science (UChicago DSI), or a closely related quant major (Computer Science, Statistics, Applied Math, the Economics Data Science specialization)
- Demonstrated ability to ship code: course projects, side projects, hackathons, research, open source — something concrete
- Data Science Clinic, DSI Summer Lab, or comparable applied project experience is a strong plus
- Willingness to relocate to Europe and embed inside a country business; EU work eligibility, or willingness to navigate the visa process with us

Education

Ideally a graduating UChicago undergraduate with a strong quantitative foundation and a serious appetite for working at the bleeding edge of AI in a real business.

COMPETENCIES

TECHNICAL

- Claude Code as daily substrate - You will prototype full small-stack MVPs with AI-assisted development. You are not expected to write production code — Claude Code plus the Casablanca dev team are the substrate.
- LLM agent orchestration - Prompt engineering, retrieval (RAG), tool use, MCP servers, multi-step agent flows. Comfort here can be built in the first months, but you should have already played with agents in a meaningful way.
- Coding fluency - Read and write Python (and ideally some TypeScript) well enough to ship and debug an MVP.
- Comfortable with Git, APIs, and a basic database (Postgres or Mongo).
- Workflow architecture - Decompose a messy human process into discrete, automatable steps with clear handoffs and decision branches.
- No-code / low-code awareness - Familiarity with n8n, Zapier-class tools, or equivalent for fast integration wiring.
- Data analysis - Pull raw data, draw conclusions, present them to a non-technical stakeholder.
- Documentation - Write clean technical specs, runbooks, and acceptance criteria. The Casablanca team should be able to take over without you in the room.

PRODUCT & BUSINESS

- Developing business intuition - You will not arrive with senior business judgement — but you must be the kind of person who can sit in an ops meeting, ask the right three questions, and locate the automation seam within a couple of weeks of exposure.
- Voice of the customer - Represent the consultants and Business Partners to the Casablanca team, and the Casablanca team's constraints back to the business.
- MVP discipline - Define the smallest valuable slice and ship it; resist scope creep.
- Backlog ownership - Hold a single source of truth for country automation work and prioritize ruthlessly by value × difficulty.

SOFT SKILLS

- Autonomy and rigour - Own the country backlog end-to-end; clean specs, clean handoffs, clean follow-through.
- Active listening and empathy - Business Partners must trust you enough to show you the real workflow, not the sanitized version.
- Comfort with constant change - The toolchain will evolve quarterly; this is a feature, not a bug.
- Creative reasoning - A well-made head that reasons fast. Creativity over experience — exactly what this role is calibrated for.
- Appetite for Europe - You want to spend the next chapter of your career embedded in a European business, in a European country, learning a European language at working level.

What You Will Not Do

- Write or maintain production code — Casablanca dev team owns this.
- Manage people — IC role; your peers are the other country BSAs.
- Cross-country project ownership beyond pattern sharing — one country, deep.
- Sales or client delivery — you sit next to Business Partners, you do not replace them.
- Long-running quarter-scale builds — if a workflow cannot be MVP'd in six weeks, re-scope it.

LOGISTICS

- Location: One of Leyton's European country business units. Italy is the first instance live; Spain, Germany, Poland, Sweden, France, and the UK are next. Placement is matched to language fit and country readiness.
- Working language: English internally; comfort (or willingness to learn quickly) in the country language is a meaningful plus.
- Reports to: The country BU Director functionally, with a dotted line to the group Transformation Office.
- Growth path: This role is calibrated as a first job with real ownership. The natural evolution is toward country Head of Automation, group-level platform work, or a pivot into a country operating role.
