Senior Full Stack Data Engineer

Location:

London, UK or Durham, NC

October 14, 2026

Hive Science is a tech start-up whose technologies are in use by many of the world’s largest brands including Land Rover, Edward Jones & numerous other fortune 500 brands. The Hive platform is delivering novel intelligence at the intersection of quantitative social psychology, behavioral science & AI/ML to accelerate & transform how work is done. We’re looking for someone to join our team and get on board this rocket ship with us..

About the role:

You'll help design & drive the data infrastructure behind Hive's enrichment products: how Hive intelligence is joined to external client & partner datasets. You'll design & build extensible, repeatable systems and integration capabilities to allow for the same core intelligence to append to partner & customers' data. You'll join the product team and work alongside our existing data engineering team, which runs Hive's core platform. You'll move quickly, build what's needed and harden it for production

‍

Build infrastructure that ingests, links, transforms, enriches and delivers Hive intelligence across external data providers and customers, with bidirectional flows in each destination's required format.
Build repeatable onboarding for customer first-party data, covering intake, validation, standardisation and integration with Hive's existing data architecture.
Design for rapid onboarding of new datasets, schemas, grains and keys, with clear boundaries between core platform and partner-specific configuration.
Build reusable record linkage, key mapping, schema mapping, data contracts, validation and output generation across audience, segment and geographic grains.
Automate QA for coverage loss, join-rate changes, schema drift and geographic mismatches, with lineage from source to final output.
Partner with our data engineering team to strengthen shared infrastructure and pipelines for reliability, monitoring and scale.

‍

Requirements:

Production data platforms with high-volume ETL/ELT, distributed processing and orchestration (e.g. Airflow, Dagster, Prefect), as distinct from analytics pipelines.
Python and SQL at a high level, plus Bash automation.
Cloud infrastructure, with AWS preferred (S3, Lambda, ECS, IAM); Snowflake and/or Databricks; Docker; CI/CD (GitHub Actions or similar); Infrastructure-as-Code (Terraform or CloudFormation).
Record linkage and entity matching across heterogeneous datasets.
Data clean-room set-up and integration (Snowflake, AWS Clean Rooms, InfoSum, Databricks or similar).
Geospatial data engineering: spatial SQL, geographic indexing, Census geographies, crosswalks and large-scale spatial joins.
Database design and scaling: SQL, NoSQL, vector DBs (Pinecone, FAISS), graph DBs (Neo4j).
Privacy and security engineering: aggregation thresholds, suppression rules, role-based access, encryption at rest and in transit, secrets management, lineage and audit.
Automated external data acquisition (APIs, feeds, scraping) built for continuous updates rather than one-off pulls.
API development (FastAPI/Flask, REST/GraphQL).
Monitoring and alerting across models and infrastructure (CloudWatch, Prometheus/Grafana, Sentry or similar; MLOps).
AI and ML integration: productionising models (embeddings, LLMs); orchestrating LLM and NLP pipelines; ETL for training and inference data.
Fluency with Claude Code: you use AI coding agents daily, and they make you meaningfully faster.
External data providers, consumer or audience data, or data marketplaces
A degree in Computer Science, Engineering, Mathematics or a related field, or equivalent experience.

Nice to have

Synthetic data generation and validation for testing and privacy-preserving development.
MCP integration with data sources and agents.
Frontend basics (React/TypeScript) for internal tools and QA dashboards.
Early-stage or high-growth startup experience.
