About the Company 

The mining industry has steadily become worse at finding new ore deposits, requiring >10X more capital to make discoveries compared to 30 years ago. The easy-to-find, near-surface deposits have largely been found, and the industry has chronically under-invested in new exploration technology, relying on the manual techniques of yesteryear – even as demand accelerates for copper, lithium, and other metals to build electric vehicles, renewable energy, and data centers.

KoBold builds AI models for mineral exploration and deploys those models—alongside our novel sensors—to guide decisions on KoBold-owned-and-operated exploration programs. In the six years since founding, KoBold has become by far both the largest independent mineral exploration company and the largest exploration technology developer. Our data scientists and software engineers, who come from leading technology companies, jointly lead exploration programs with our renowned exploration geologists.

KoBold has proven its first discovery with materially less capital than the industry average and found one of the best copper deposits ever discovered: the copper is far more concentrated than the global average of copper mines, and this asset alone is expected to generate meaningful revenue for decades. KoBold has a portfolio of more than 60 other projects, each of which has the potential for another high-quality discovery.

About the Role

In this role, you will lead evaluations of potential properties for staking, partnering or acquisition, generate targets, and design and oversee field programs from target definition through to resource expansion. You will be part of a multidisciplinary team and will work closely with data scientists, using KoBold’s technology to help guide our field programs and decision-making. You will also work directly with our senior technical advisors and with the executive team on making the investment case for acquisitions and field programs.

Ultimately, your role is to help KoBold make valuable discoveries by identifying opportunities with rigorous evaluation and by ensuring that we safely and effectively conduct our field programs.

Responsibilities

Software Engineer

About the company: 

The mining industry has steadily become worse at finding new ore deposits, requiring >10X more capital to make discoveries compared to 30 years ago. The easy-to-find, near-surface deposits have largely been found, and the industry has chronically under-invested in new exploration technology, relying on the manual techniques of yesteryear – even as demand accelerates for copper, lithium, and other metals to build electric vehicles, renewable energy, and data centers.

Rowe Price and Canada Pension Plan Investments; technology venture capitalists Andreessen Horowitz, Breakthrough Energy Ventures, BOND Capital, and Standard Investments; and natural resources companies Equinor, BHP, and Mitsubishi.

We are hiring Software Engineers to accelerate our mission.

About The Role:

At KoBold, software engineers have the unique opportunity to embed directly with their users and learn the ins and outs of mineral exploration and geology while developing state of the art technology solutions. Unlike traditional software engineering roles, we don’t simply ship code and passively wait for feedback about its utility: our userbase includes our colleagues… and ourselves! While there are real technical challenges in making mineral exploration data broadly searchable and accessible to both humans and machines, we believe that solving these technical challenges cannot be done without “getting our hands dirty” – sometimes literally! – by embedding directly with the exploration teams and even occasionally (~once a year) joining our colleagues in the field, be it in Zambia, Canada, or Arizona, to experience the impact of our software in real time.

As a Software Engineer on the Data Systems Engineering team at KoBold, your main role will be to enable systematic exploration and materially improve exploration success rates by making mineral exploration data broadly accessible to humans and machines.  Past projects have included SIP (the Structured Ingest Pipeline), DataKit generation (producing curated sets of data on demand), and RAG (Retrieval Augmentation Generation, utilizing natural language processing on unstructured data). Our tech stack is primarily python and includes Django, React, AWS, and additional technologies like Retool and Prefect. 

Your work will empower KoBold to unlock invaluable insights and streamline intricate scientific processes. Collaborating with our exceptional team of data scientists, geologists, and other software engineers, you will have the opportunity to tackle complex problems head-on and collectively pave the way for the discoveries of vital energy transition metals like lithium, copper, nickel, and cobalt. Together we can shape the future of mineral exploration and contribute to building a sustainable world.

This role be responsible for:

• Deep engagement with exploration geologists and data scientists, continual learning about mineral exploration, and tailoring technology development to the needs of exploration project scientists
• Building data pipelines and tooling for deriving advanced human and machine insights from exploration data, often leading a small group of software engineers to successful delivery
• Developing expertise in KoBold’s Data Systems and deeply understanding how they impact exploration
• End-to-end ownership of projects from design to implementation and testing to continued engagement with colleagues on exploration teams using your solutions
• Responding well to design and code feedback, also providing feedback to teammates 
• Operationally managing the team’s services and assisting scientific colleagues with our tooling

Qualifications:

• 2+ years of software engineering experience, ideally building production cloud data systems
• Proficiency with Python
• Ability to write production-quality code that is correct, readable, well-tested, scalable and extensible
• Skilled in large-scale system design
• A track record of taking ownership from definition of the problem and delivering projects with demonstrated impact in an iterative manner
• Intellectual curiosity and eagerness to learn about all aspects of mineral exploration, particularly in the geology domain. Enjoys constantly learning such that you are driving insights through using our tools in exploration and willing to work directly with geologists in the field.
• Ability to explain technical problems to and collaborate on solutions with domain experts who are not software developers. A strong communicator who enjoys working with colleagues across the company.
• Excitement about joining a fast-growing early-stage company, comfort with a dynamic work environment, and eagerness to take on an evolving range of responsibilities.
• Keen not just to build cool technology, but to figure out what technical product to build to best achieve the business objectives of the company.

Nice to Haves: 

• Experience with modern frontend frameworks such as React
• Experience with geospatial data and building map-based experiences
• Familiarity with containerization and container orchestration platforms, such as Docker, AWS ECS, Kubernetes, etc.
• Formal education or job exposure to natural sciences

About Sand

Sand Technologies is a global Physical AI company using data and AI to make critical industries work better. We partner with governments, cities and enterprises to improve how essential systems operate across healthcare, water, energy, telecommunications and infrastructure.

Our work delivers proven real-world impact. We have built AI systems that help manage London’s water supply, supported telecom network planning across hundreds of cities, and developed digital healthcare platforms serving tens of millions of people across Africa. From intelligent command centers to AI-powered infrastructure platforms, we help organizations sense, analyze and act in complex environments.

Our people are ambitious, curious and relentlessly practical. Our teams work alongside clients in the field, solving hard problems and deploying solutions that last. With colleagues across Africa, Europe, the UK and the US, we operate across the full stack - from research and engineering to deployment and capability building.

Our mission is simple: to harness AI to solve humanity’s most pressing challenges.

About the role

Sand is scaling rapidly across Africa, partnering with Ministries of Health to deploy the Health Operating System (HOS) — a decision-support and execution platform that transforms how health systems sense, analyze, and act on data. The HOS is already operational across multiple countries, with plans to expand to 15 countries by end of 2026, supported by 80+ Forward Deployed Engineers.

As a Forward Deployed Engineer (FDE), you are the technical spearhead of our client engagement in the Democratic Republic of Congo. Unlike our roaming FDE roles, this is a permanently embedded position. You will be based full-time within the Ministry of Health in the DRC, becoming a long-term extension of the client's operational team. Your mandate is to build deep institutional relationships, develop comprehensive understanding of the national health system, and deliver sustained value over an extended engagement — not just rapid sprints, but lasting transformation.

This is not staff augmentation. You are an amalgamation of three roles:

1. The Software Engineer — Deep technical acumen to build and deploy production-grade solutions using Sand's product suite
2. The Product Manager — Strategic foresight to understand client problems, influence business objectives, and identify expansion opportunities
3. The Consultant — Client-facing finesse to navigate complex stakeholder relationships, manage scope, and transfer knowledge

Your primary mission is to prove our value fast, delivering functional solutions rapidly using Sand's products, playbooks, and tools, and then maturing those solutions into mission-critical infrastructure that the Ministry depends on daily. Over time, you become the institutional memory of the deployment — the person who understands the data landscape, the stakeholder dynamics, and the operational realities better than anyone.

Who We're Looking For

The Forward Deployed Engineer is a highly ambitious individual. You are someone who is deeply keen on learning — someone who dives in headfirst to solve some of the hardest, most complex problems in global health. You thrive on understanding the technology, understanding the stakeholders, understanding our product suite, and weaving all three together to deliver solutions that change how health systems operate.

This role is not for someone looking for comfort or routine. It is for someone who wants to step outside of their comfort zone, build something they can be proud of, and grow faster than they thought possible. The FDE programme is a career accelerator — an intensive rotation that exposes you to technical depth, strategic thinking, and client leadership in equal measure, all while working on problems that matter for millions of people.

For this permanently embedded role, you also need the maturity and resilience to sustain deep client relationships over months and years — not just weeks. You will become the face of Sand in Malawi, and that requires patience, cultural fluency, and the ability to navigate institutional complexity while maintaining momentum.

Key Responsibilities

Serve as Sand's Permanent Technical Presence in the Democratic Republic of Congo

• Embed full-time within the Ministry of Health, becoming a trusted member of the client's extended team
• Develop deep, longitudinal understanding of the national health data landscape, institutional dynamics, and operational priorities
• Build and maintain relationships across all levels of the Ministry — from frontline data officers to senior leadership
• Act as the primary technical point of contact for all Sand activities in-country, coordinating with launchers, country directors, and visiting FDE teams

Drive On-Site Value Delivery

• Rapidly unlock, explore, and integrate client data sources (e.g., DHIS2, SCADA systems, network management platforms, operational databases)
• Understand client problems through prototyping and rapid value delivery — deploying POCs and MVPs using Sand's product components and playbooks
• Transition initial solutions into hardened, production-grade systems that the Ministry relies on daily
• Own the long-term health of deployed solutions — monitoring adoption, troubleshooting issues, and iterating based on user feedback
• Deliver and track value generated through deployment of Sand products

Enable Product-Led Growth

• Lead with Sand's existing product suite — know the products by heart and where each solution is most effective for the domain you're deployed in
• Document learnings, client challenges, and successful solutions as reusable patterns for the broader FDE community
• Drive discovery and expansion by uncovering new opportunities on the ground

Build Local Capacity and Sustainability

• Work alongside Ministry teams to co-create solutions and progressively transfer knowledge, ensuring they can operate and maintain systems independently
• Identify, recruit, and mentor local data engineers, scientists, and analysts to build sustainable in-country capacity
• Develop training materials and documentation tailored to the local context, language, and skill level
• Be the continuity that ensures handover isn't a cliff — you bridge the gap between Sand's deployment and the Ministry's long-term ownership

Feed the Platform Feedback Loop

• Channel field learnings back to improve the core product through structured mechanisms (Technical Deep Dives, Solution Swarms, pattern documentation)
• Turn "gravel roads" into "paved superhighways" — document solution patterns so the next FDE can move faster
• Contribute field feedback that influences 30% of the product roadmap

Requirements — Essential

• Bachelor's degree in Computer Science, Engineering, Information Systems, or related technical field
• 5+ years of experience in software engineering, data engineering, data science, system deployment, or technical leadership
• Proficiency in at least one of: Python, SQL/PostgreSQL, JavaScript — with ability to write production-grade code
• Strong problem-solving skills with a bias toward action and rapid prototyping
• Excellent communication and stakeholder management skills — comfortable presenting to senior government or corporate stakeholders and translating between technical and non-technical audiences
• Experience working with or deploying to government, public sector, or large institutional clients
• Proven ability to lead local technical teams and build capacity
• Willingness to relocate and be permanently based in the DRC for the duration of the engagement (12-24+ months)
• Language: Local language proficiency is a significant advantage

Requirements — Preferred

• Experience with data integration, ETL pipelines, and working with diverse data sources
• Experience in one or more of Sand's focus domains: health informatics/digital health, water utility operations, telecommunications network operations, or energy systems
• Familiarity with domain-specific platforms (e.g., DHIS2, OpenMRS for health; SCADA, GIS for water/energy; OSS/BSS for telecom)
• Experience with BI and dashboarding tools, particularly Apache Superset
• Experience with data transformation tools such as dbt or Airflow
• Comfort working with data dictionaries, reporting requirements, and identifying common data quality issues
• Knowledge of data security, privacy, and interoperability standards (e.g., FHIR for healthcare, GDPR, local data sovereignty requirements)
• Experience operating in resource-constrained environments (unreliable power, limited connectivity)

Work Environment

This is a permanently embedded role. You will work on-site at the Ministry of Health in the DRC 4 days per week, with 1 day for focused remote work, internal collaboration, and knowledge sharing with the broader FDE community. You should expect to be based in the DRC for a minimum of 12-24 months.

You must be self-driven, comfortable operating as Sand's primary technical representative in-country, and disciplined with online collaboration tools to stay connected with the broader Sand team across geographies. Cultural sensitivity, adaptability, and genuine interest in the local context are essential — you are not passing through, you are putting down roots.
