WOODY, our recently launched platform for analyzing mine economics and comparing investment opportunities, is your starting point. From there your work spans the rest of the portfolio: subscription tools used by mining engineers and analysts, reporting and benchmarking workflows, marketing surfaces, and new products on the roadmap. This is an early-career role for someone with roughly 0–3 years of experience who wants to grow quickly with strong mentorship. The senior leads architecture and bigger technical calls; you’ll pick up well-scoped components, screens, and backend-for-frontend endpoints, and grow into owning small features end-to-end. Expect frequent pairing, code review on every PR, and visible work shipping to customers. A separate 4-person backend team owns core data infrastructure; you’ll work above their APIs. Why It’s Technically Interesting Mining cost analysis has problems you won’t find in typical B2B SaaS: Domain modeling: Translate mining concepts — grade recovery, waste-to-ore ratios, haulage profiles — into UX that investors and engineers can actually use Multi-audience surfaces: The same data is reshaped for investors (simplified), analysts (comparative), and engineers (detailed); information architecture matters Rich data relationships: Highly interconnected cost data with deep metadata; you’ll learn to think carefully about queries, filtering, and navigation Specialized visualization: Standard charts don’t cut it for mining economics; you’ll build domain-specific ones alongside the senior What You’ll Actually Build WOODY (first 3–6 months) — working alongside the senior on existing HTML/CSS prototypes and early React components: Investment comparison dashboard: components and screens that let analysts compare mine economics side-by-side Interactive cost scenario builder: UI for modeling cost assumptions and seeing real-time impact on project economics Backend-for-frontend (React Router): loaders, actions, and server functions that transform our C# backend data for the frontend — starting well-scoped and growing into more complex pieces Across costmine.com (ongoing): Beyond WOODY, you’ll contribute to the rest of the surface — subscription tools for mining engineers and analysts, reporting and benchmarking workflows, and new products in flight. Expect to move between codebases: a small dashboard improvement one week, a new BFF endpoint for WOODY the next, a marketing page after that. Requirements Must Have: TypeScript, React, Node.js fundamentals — you’ve shipped working code in these (school projects, internships, side projects, or 1–3 years of professional experience all count) Eager to learn — you ask questions, take feedback well, and iterate Clear communication — you can explain what you’re doing and where you’re stuck; critical in a small remote team Already working with AI-assisted development — we use Claude Code heavily, and we expect you to lean into it as a core part of how you work. You should already have hands-on experience with Claude Code, Cursor, Copilot, or similar; deep expertise isn’t required, but never having tried these tools would be surprising at this point. Drawn to specialized domains — mining cost analysis should sound interesting, not intimidating Comfortable with early-stage ambiguity — small product team, processes are still forming; lean on the senior for guidance Nice To Have: Data-heavy app experience (complex filtering, relationship navigation, specialized visualization) Python (our long-term backend direction) Internship or job at a small/early-stage team B2B SaaS exposure Team & Growth Today: 4 backend developers (Python/C#) plus our senior full-stack — you’d be the second on the product side Your role: pair to the senior across the user-facing layer, with frequent mentorship and code review In 12–18 months: confidently owning small features end-to-end across multiple products This is a great fit if you want strong mentorship, product work that ships, and the kind of trajectory you only get on a small team where your contributions are visible across the whole product. Tech Stack Frontend: TypeScript, React Backend-for-Frontend: React Router (running on Node.js) Core Backend: C# (majority), Python (growing) — owned by a separate team Data: Complex mining cost database with rich relationships and metadata Workflow: AI-assisted development is core to how we work; prototype-first; iterate with customers; remote-first and async-friendly What We Offer: Hands-on mentorship — a senior full-stack and a hiring manager who care about your growth Visible work — newly launched product with users and short feedback loops An interesting domain — 40+ years of mining data and specialized problems with genuine depth to learn Modern tooling — AI-assisted development as a first-class part of the workflow Remote-first — work from anywhere, as long as your day overlaps North American hours Fair compensation — we’re not competing with FAANG, but we pay fairly for the experience level (range varies by region) Not a Fit If: You want fully autonomous work with little review You prefer mature processes and detailed specs You’re not interested in learning a specialized domain You expect big-tech salary levels Next Steps: We move quickly. We’re looking for someone who can start contributing on WOODY soon and grow into work across the rest of costmine.com as the portfolio scales. Interested candidates should send a résumé and cover letter to support@costmine.com . Costmine Intelligence is committed to building a diverse and inclusive team.

See where capital estimates converge once scope is normalized, why the operating cost gap stays modest, and what this level of alignment signals about the integrity of the 2026 Technical Report. Costmine Team May 28, 2026 Data Showcase WOODY v. Taca Taca Comparison – Excel Data Download In this analysis, Costmine Intelligence applied WOODY, our proprietary benchmarking platform, to First Quantum’s Taca Taca Copper Gold Project, building independent capital and operating cost estimates from current market rates and location-adjusted inputs. The results offer a like-for-like comparison against the 2026 Technical Report once scope items are normalized. Costmine Team May 27, 2026 Insights Mission Impossible: Truly independent mine cost analysis? Reliable mining investment decisions require more than operator-reported forecasts. New analysis from Costmine finds OPEX estimates in feasibility studies lag independent benchmarks by 39% on average, with CAPEX variance averaging 26% across projects in Canada, Chile, the US, Mexico, Australia, and Pakistan.
