Senior Software Engineer - Data Platform

About Andrenam We’re building sonar and sensing systems that bring light to the last dark domain: the ocean. Our team includes alumni from SpaceX, Anduril, ABL, Palantir and Qualia. We build full-stack—from physics to perception to product—with speed, elegance, and an unwavering commitment to the mission. We believe the maritime domain will define the next century of geopolitics and global security. We’re here to shape it. About this role AndrenaM is seeking a Senior Software Engineer - Data Platform who is passionate about advancing autonomy and real‑time maritime communication technology. We’re looking for a talented and motivated engineer to join our team. This is a unique opportunity to be a core part of our founding team, shaping the product and technology from the ground up. Our main engineering challenge is to develop a real‑time ML data platform that can ingest, process, store, reprocess, and analyze data from thousands of autonomous and semi‑autonomous marine systems. This system must seamlessly handle a wide variety of sensors, hardware interfaces, data sources, and AI‑driven analytics—with military‑grade security, reliability, and reproducibility. In this role You will define how raw maritime signals become clean, consistent, labeled datasets for perception and foundation models. You will prioritize dataset quality, reproducibility, and evaluation fidelity. You will collaborate closely with ML/perception to map data contracts to model needs. Responsibilities Build and operate post‑processing pipelines that align, resample, and calibrate multi‑sensor data. Implement robust backfill/reprocessing frameworks to apply new filters, synchronizations, label corrections, and metadata enrichments across historical data. Establish lineage & versioning to guarantee experiment reproducibility. Build dataset discovery & access APIs/SDKs so downstream users can query by time, region, modality, labels, and quality flags. Instrument data quality metrics (completeness, corruption, drift, label density, class/region balance) with dashboards and alerts; run canary dataset builds. Optimize storage layouts for fast reads and parallelization (columnar formats, compression codecs, chunking strategies, sharding, locality, prefetching). Some types of experiences we're especially excited to see Demonstrated ownership of dataset‑as‑a‑product: curated corpora supporting multiple model families with strong lineage and documentation. Experience designing splitting/sampling strategies (by time, platform, geography, class, SNR) to avoid leakage and ensure generalization. Hands‑on with labeling workflows (interfaces, ontologies, consensus, QA) and label‑store integrations. Proficiency in Python and data tooling (PyArrow/Polars/Pandas, NumPy/SciPy, audio/vision libs), plus one of Go/Rust/TypeScript for services. Comfort with orchestration (Airflow, Prefect) and metadata/lineage (MLflow, W&B). Exposure to edge/sensor data (audio/sonar, video, telemetry), time sync, and geospatial context. Why join us? Andrenam is an innovative, mission-driven company at the intersection of maritime autonomy and defense. We offer: Competitive salary Long-term equity incentive program with significant growth potential. Flexible PTO and paid holidays. Comprehensive medical, dental, vision insurance. 401k Lunch and snacks provided in office. Access to a unique work environment, blending technology, maritime, and defense.
