Full Stack Engineer - ETF Focus

### **About Us** Corgi is building an ETF issuer that moves at software speed. ETFs are one of the most successful financial products ever created — and the tooling behind launching, operating, and reporting for ETFs is still stuck in email chains, PDFs, and manual checklists. Our goal is simple: **turn ETF operations + compliance into software**. If you like hard systems problems, messy real-world constraints, and shipping things that immediately matter, you’ll fit right in. ### **About the Role** You’ll build internal products (and public-facing web surfaces) that make launching and running ETFs faster, more consistent, and more observable.

You’ll work close to real workflows: regulatory filings and disclosure updates, approvals and evidence capture, fund accounting interfaces, vendor data, board materials, compliance logs, QA, reporting, and analytics. This is an end-to-end role: you’ll design workflows, build backend services and data pipelines, ship polished UIs, and run production systems. Our backend demands correctness, traceability, and auditability; our public web presence demands visual polish and high-performance UX. **Skills:** Python, TypeScript, SQL, AWS (or equivalent), strong product/ops instincts. ### **What You’ll Build (examples)** ### **1) Filing Automation + Disclosure QA** * Generate, edit, and QA disclosure content; enforce versioning, approvals, and checklists/redlines. * Produce SEC EDGAR-ready outputs, including support for Inline XBRL (iXBRL) tagging/validation where applicable. ### **2) Compliance Workflows** * Codify policies into systems (controls, approvals, escalation paths). * Build permissioned workflows with evidence capture (what changed, who approved, when, and why). * Implement change control, audit-ready logs, and review queues aligned with U.S.

Securities and Exchange Commission expectations. ### **3) Data Pipelines + Vendor Integrations** * Ingest holdings/prices/corporate actions/vendor files via SFTP and APIs. * Reconcile data, surface exceptions, and build monitoring/retry tooling. ### **4) Automated Fund Presence “source of truth”** * Own the automated “source of truth” for our funds: systems that take vendor/fund-admin data (SFTP/API) and power our public fund pages and internal analytics. * Build guardrails around data provenance, versioning, and reconciliation so changes are explainable and reviewable. * Design exception queues and operational tooling so issues are visible, triaged, and resolved quickly. ### **5) Public Web Surfaces & Investor Analytics** * Develop and scale our web infrastructure for reliability, performance, SEO, and accessibility. * Build interactive investor tools: performance calculators, comparison tools, and exposure breakdowns that are fast and mobile-responsive. * Security-first mindset: implement WAFs, secure header management, sensible access controls, and operational monitoring for public web services. * Your work will be a primary interface for investors—turning complex fund data into clear, usable, and visually polished web experiences. ### **6) UI Design + Product Execution** * Create and implement beautiful, efficient internal tools: fast UIs, clean information architecture, and sensible defaults. * Collaborate in Figma and carry designs through to high-quality implementation. * Sweat details: loading/empty states, error handling, permissions, and review/approval flows that feel obvious. ### **You’ll Thrive Here if You** * Have interest in the financial markets, especially ETFs. * Can own features end-to-end (backend → UI → deployment). * Are familiarity with SEC EDGAR–related workflows and Inline XBRL (iXBRL) concepts (or ability to ramp fast). * Have experience building dashboards, charting, reporting UIs, and analytics products (interactive tables, performance charts, exposure breakdowns). * Have production experience operating systems on major cloud infrastructure (AWS, GCP, or Azure). * Love turning ambiguous ops problems into clean systems. * Are comfortable with regulated/controlled environments (auditability matters). * Write maintainable code fast, and care about correctness. * Have strong UI judgment and ability to implement clean, fast interfaces. ### **Nice to Have** * Fintech, markets, accounting, or compliance experience. * Experience with LLM-assisted tooling (retrieval, evals, guardrails, human-in-the-loop review). * Familiarity with ETFs / fund ops / reporting (you can learn fast if you’re sharp). * Experience with iXBRL tagging/validation and SEC filing workflows. * Experience with quantitative trading or systematic investing. ### **Why Join** * **Real leverage:** your tools will compress weeks of work into hours. * **High ownership:** you’ll shape the product surface area, architecture, and standards. * **Direct impact:** every improvement hits real workflows immediately. ### **Location** Chicago ### **How to apply** Send: (1) a couple sentences on why this is interesting, (2) your resume/GitHub/links, and (3) Demo a project that could help the team on day 1; (automated compliance tool for an ETF issuer, Software to automate N-Port filing, etc.)
