Founding Geospatial Data Engineer

Founding Geospatial Data Engineer

£60–80k + Equity/Stock Options

London (Hybrid)

This is a founding role building the system Apexion will scale on for the next decade.

Apexion - Building the next-generation geospatial intelligence platform:

A scalable digital twin that unifies infrastructure, energy, buildings, land, and grid systems into one decision making engine.

We're starting with UK commercial rooftop solar - building a national intelligence system for all 2.5 million commercial buildings, integrating high-res imagery/DSM, digital twins, energy data, and ownership/occupancy to let developers and investors filter, evaluate, and accelerate commercial solar decisions.

The vision:

Make geospatial intelligence directly usable in real commercial decision-making - enabling industry, investors, and policymakers to accelerate the speed and scale of climate projects.

Where We Are TodayInitial traction

• Early demos supporting £150M+ in commercial solar projects with major PPA funds/developers.

Strong data foundation

• Full UK building dataset: UPRN, footprints, EPC, energy use, land-use
• Partnership for 5–12.5 cm high-res imagery + DSM/DTM (England & Wales)

Architecture Outlined (White Box Build)

• High-level system architecture + constraints mapped (ingestion → processing → modelling → API)
• Rooftop workflow outlined (segmentation, tilt, shading, viability)
• V1 scope defined - ready for you to architect, implement, and own end-to-end
• Big-picture roadmap mapped - with space for you to shape vertical expansion, product evolution, and engineering direction

Funding secured

Capital committed for system build-out and continuous development throughout 2026, ahead of a cornerstone Seed/Series A.

The Role

We're hiring the Founding Geospatial Data Engineer - the person who will design and build Apexion's technical foundation and surrounding infrastructure.

This role suits someone who thrives in fast-paced, high-intensity environments - the pace here is closer to an early-stage technical founder than a typical 9-5 engineering job.

You will:

• Architect the full end-to-end system (ingestion → processing → modelling → API)
• Build scalable pipelines for millions of buildings
• Develop 3D/DSM/DTM + computational geometry workflows
• Define viability logic and geospatial algorithms
• Establish naming conventions, data structures, and documentation
• Build a foundation that scales into future verticals (EV, heat, grid, nature, etc.)
• Own long-term technical decisions and system evolution
• Be hands-on first; hire and lead engineers as the team grows
• Grow into a Senior role as the company scales

You will have full architectural autonomy - no legacy systems, no inherited codebase. You choose the tooling, standards, and workflows that Apexion builds on for the next decade.

This is a hands-on systems role forming the backbone of the company.

What We're Looking ForTechnical

You have strong experience building geospatial systems, ideally across many of:

• LiDAR / DSM / DTM / point clouds / 3D meshes
• Large-scale geospatial or remote-sensing pipelines
• National-scale ingestion, processing, and automation
• Raster + vector fusion workflows
• Python (GDAL, Rasterio, Shapely, GeoPandas, etc.)
• Cloud-first storage/compute (AWS/S3)
• Computational geometry + 3D modelling logic
• Designing geospatial systems from the ground up
• Performance optimisation at national or continental scale

Solar modelling or energy systems knowledge is a bonus, not a requirement.

Leadership & Ownership

You are someone who:

• Wants to own the system architecture long-term
• Thinks in systems and pipelines, not isolated scripts
• Enjoys greenfield, technically complex builds
• Cares about documentation, clarity, and scalability
• Thrives with autonomy and doesn't need hand-holding
• Is motivated by equity, early responsibility, and legacy-level work
• Wants influence over roadmap, architecture, and product evolution

Ideal Backgrounds

• Senior geospatial engineer
• Geospatial systems architect
• Technical lead on a remote sensing / GIS / LiDAR / mapping platform
• Or a highly capable engineer who has built complex systems end-to-end

Compensation

£80–100k + equity/stock options.

Designed to reflect:

• early ownership and responsibility
• long-term contribution to the company's technical foundation
• impact on architecture, scalability, and future engineering direction

Clear pathway to senior technical leadership as Apexion scales.

Why This Role Matters

You'll architect the system Apexion will scale on for years - from today's national solar intelligence layer to a future global digital twin used by industry, investors and policymakers.

A rare national-scale build from day one - foundational work that brings geospatial intelligence into the mainstream and accelerates real-world infrastructure and climate decisions at massive scale.
