About SatSure
SatSure is a deep tech, decision intelligence company working at the nexus of agriculture, infrastructure, and climate action — creating impact for the other millions, with a focus on the developing world. As part of this mission, we're building geospatial foundation models that learn directly from Earth observation data — optical, SAR, and elevation — at scale. This role sits at the heart of that effort: architecting and training large-scale models that can generalize across geographies, sensors, and time. You'll be shaping the core intelligence layer that powers insights for millions, not just fine-tuning someone else's model.
Role
You will be the architect of the model’s latent space, designing foundation models for multi-spectral, multi-temporal, and multi-resolution geospatial data.
This is a hands-on role involving prototyping, experimentation, and large-scale training. You will work across representation learning, model scaling, and spatiotemporal modeling to build systems that generalize across sensors, geographies, and time.
Key Responsibilities
Representation Learning
  • Design and implement self-supervised learning (SSL) objectives (e.g., Masked Autoencoders, DINO-style methods, contrastive learning) tailored for geospatial data
  • Develop multi-modal representations spanning optical, SAR, elevation, and derived signals
  • Ensure representations transfer effectively across tasks such as segmentation, classification, and change detection
  • Design evaluation strategies to measure generalization across geographies, sensors, and time
Model Development & Scaling
  • Design and scale models based on Vision Transformers (ViT), hybrid architectures, or State Space Models (e.g., Mamba) to large parameter regimes
  • Apply modern training techniques such as RMSNorm, FlashAttention, mixed precision, and gradient checkpointing
  • Run scaling experiments, ablations, and architecture explorations grounded in empirical rigor
  • Leverage insights from scaling behavior to make compute-efficient decisions across model size, data, and training strategy
Temporal Dynamics
  • Develop methods to model time-series satellite data, capturing:
    • Seasonal patterns
    • Temporal dependencies
    • Long-term land-use changes
  • Explore sequence modeling, memory mechanisms, and temporal tokenization strategies
Systems-Level Thinking
  • Design ML systems as end-to-end pipelines (data ingestion → curation → training → evaluation → deployment → feedback)
  • Make explicit trade-offs between model quality, latency, cost, and data freshness
  • Work with platform teams to optimize:
    • Distributed training (FSDP, DeepSpeed)
    • GPU utilization
    • Data pipelines and experiment throughput
  • Build reusable components and abstractions, not one-off models
Preferred Background
Experience
  • 3–5 years of experience in ML research or applied research roles
  • Experience in large-scale foundation model development (vision, multimodal, speech, or related domains)
  • Experience training and/or fine-tuning billion-parameter models
  • Experience working with sequence, video, or temporal data
  • Exposure to geospatial foundation models, such as:
    • Prithvi
    • Clay
    • Segment Anything Model (SAM) (nice to have)
Technical Skills
  • Expert-level proficiency in PyTorch or JAX
  • Strong experience with:
    • Distributed training (FSDP / DeepSpeed)
    • Large-scale datasets and training pipelines
  • Familiarity with transformer architectures and training dynamics
  • Bonus: CUDA / performance optimization experience
Additional Strengths
  • Familiarity with efficient scaling techniques (e.g., Mixture of Experts) is a plus
  • Strong experimental rigor and ability to design meaningful ablations
  • Track record of publishing or contributing to state-of-the-art research in representation learning or generative modeling
