About Us Jupiter is the global market leader in analytics for resilience planning and enterprise climate risk management. We are led by pioneers in data, climate, and earth and ocean sciences, as well as technology, risk management, company building, and public policy. Our climate risk modeling solutions save lives and mitigate potentially catastrophic impacts inflicted by hurricanes, floods, heat waves, wildfires, drought, and other extreme weather events on homes, businesses, infrastructure, food and water supplies, and entire economies. Jupiter is also committed to the world community. Through our Jupiter Promise initiative we provide services to under-resourced countries and communities to promote sound decision making while including the potential impacts of climate change. Employees are encouraged to provide their expertise to various programs under the Jupiter Promise initiative. Jupiter is bringing diversity to prepare a diverse planet for our changing climate. Jupiter was founded on the principle that with the right approaches and the right team, we can prepare Earth’s economies to meet the challenges associated with climate change. The world is a diverse place; a diverse workforce in an inclusive environment is essential to meet our goals. We go forward together. Jupiter seeks a highly skilled Flood Modeler (contract), with a specialized focus on development and execution of shallow water flood models to support our high-resolution flood modeling pipelines. The purpose of this role is to develop and deploy complex modeling frameworks to simulate and predict flood risk on commercial cloud platforms. This role will involve deploying algorithms for numerical simulation/prediction of flood risk resulting from rainfall, river flow, and coastal storm surge. This role involves troubleshooting complex algorithms, applying code iteratively to test new settings, contributing to process workflows, and assuring quality of output. This role is a critical piece of the team delivering data that forms the backbone of Jupiter products. What You Will Do Develop and execute high-resolution, fluvial, pluvial, and coastal flood inundation models. Collaborate with science and software engineering teams to integrate solutions into scientific processing workflows and perform quality control assessments. Work independently within an interdisciplinary team environment. Technical Aspects of the Role 2-dimensional flood model design and deployment (e.g. HEC-RAS, LISFLOOD, TUFLOW, Telemac, or similar) Model parameter optimization Model validation and verification Geospatial data processing (QGIS, ArcGIS) Strong knowledge of Python and experience with libraries such as NumPy,  GDAL, Rasterio, Xarray, and Pandas Familiarity with software engineering best practices and cloud computing Fortran experience a plus What You Will Need to Stand Out Master’s degree in Civil/Environmental Engineering, Coastal Engineering, Water Resources, Fluid Mechanics, Hydrology or related field Bachelor's degree plus 3-5 years experience also considered Experience modeling channel, coastal and floodplain inundation hydrodynamics Experience scaling computational methods for large-scale processing (Docker containers, Kubernetes, AWS EC2, Dask, multiprocessing) When we say Jupiter Intelligence is an Equal Opportunity Employer, we are not just adding a legal addendum.  Of course, we do not discriminate: Jupiter Intelligence is an equal opportunity employer to all, regardless of age, ancestry, color, disability (mental and physical), exercising the right to family care and medical leave, gender, gender expression, gender identity, genetic information, marital status, medical condition, military or veteran status, national origin, political affiliation, race, religious creed, sex (includes pregnancy, childbirth, breastfeeding and related medical conditions), and sexual orientation.

About the Company Anspar Foundation is building a patient-facing mobile application for Cure HHT, the leading international patient advocacy organization dedicated to supporting individuals and families affected by Hereditary Hemorrhagic Telangiectasia (HHT) — a rare inherited bleeding disorder affecting 1 in 5,000 people worldwide. Our Flutter-based mobile app helps patients track symptoms, supports clinical research, and contributes to the development of new therapies. This role focuses on stabilizing and improving the reliability of the application. About the Role We’re looking for a sharp, self-organized Flutter developer to join us on a short-term contract to help stabilize our mobile application. You will focus entirely on fixing bugs, improving reliability, and resolving issues across iOS and Android. This is a hands-on, fast-paced role — you’ll be jumping into an active project, analyzing and fixing issues, and helping ensure the app works smoothly for patients and researchers alike. What You’ll Do - Identify, investigate, and fix bugs in a Flutter (Dart) mobile application - Debug issues across iOS and Android devices and simulators - Work with backend APIs to reproduce and resolve errors - Review crash reports, logs, and analytics to prioritize and address critical issues - Collaborate closely with the Principal Engineer to understand issues and validate fixes - Improve app stability and reliability without introducing regressions

• Own protocol development on HyperEVM, including the design, implementation, and deployment of production-grade smart contracts powering positions, collateral management, fee routing, and settlement flows • Architect DeFi primitives end-to-end, such as staking and locking mechanisms, liquidity and fee systems, vaults, and risk controls (circuit breakers, caps, kill-switches, guardians), with explicit gas and latency budgets • Design and implement safe upgradeability strategies (UUPS, transparent, beacon), including storage-layout testing and invariant preservation through migrations and staged rollouts • Lead security and correctness efforts by modeling MEV and price-manipulation threats, writing invariants and fuzz tests (Foundry, Echidna), integrating static analysis tools (Slither), managing audit scope and responses, and owning post-mortems • Drive operational excellence by defining on-chain SLOs, emitting analytics-ready events, building monitoring and alerting systems, and owning incident response, rollback, and patch runbooks
