About Arbonics

Together with landowners, Arbonics is building a new forest economy to scale forest carbon removal and increase the biodiversity of European forests. Arbonics was founded in 2022 by Kristjan Lepik and Lisett Luik, and is backed by Taavet Hinrikus, Plural Platform, and Nordic Ninja.

The role

You'll be joining our 3-member technology team as a core technical voice from day one, making architectural decisions on greenfield systems like our digital twin, and shaping how we build as the team scales.

What You'll Build

External Product (≈40%): You'll build features for our Landowner Portal, handling onboarding, data collection, project tracking, and credit forecasting.

Internal Tools & Infrastructure (≈60%): You'll develop data ingestion pipelines, verification workflow automation, and contribute to our digital twin system - the auditable representation of each land parcel.

You'll collaborate closely with our Head of Product to shape solutions, our GIS Lead on spatial data workflows and the digital twin, and our Head of Verification on audit-ready systems.

What you won't be doing

Waiting for pixel-perfect specifications before starting
Building features without understanding why they matter
Pure backend/infrastructure work (you'll touch the full stack)
Extensive discovery work (we shape problems; you determine implementation)

What we're looking for

Required

3+ years as a full-stack engineer
Strong React experience (we use Remix.js extensively)
Back-end experience with Java and Spring Boot or similar
Comfort with relational databases and SQL
Experience with cloud infrastructure (AWS, GCP, or Azure)
Fluency in English

Valued

Experience working with complex or spatial data (GIS, geospatial, scientific data)
Data pipeline and ingestion experience (parsing structured/unstructured documents, ETL workflows)
Early-stage startup experience where you balanced quality with speed
Building tools for internal users alongside external products
DevOps capabilities (we don't have dedicated infrastructure engineers)
5+ years experience and ready to take on architectural ownership and technical leadership

Why join Arbonics

Impact: Forest carbon removal is essential climate infrastructure. The work directly contributes to removing CO₂ and restoring European forests.

Technical Challenge: Complex domain combining forestry science, geospatial analysis, carbon accounting, and regulatory compliance. You'll work on interesting problems like building data ingestion pipelines for disparate European forestry data sources and building our digital twin - the auditable representation of every land parcel.

Ownership: Small team means high leverage. Your decisions matter. You'll have autonomy to decide how things get built and influence our technical direction.

Team: Work alongside specialists in forestry, GIS, verification, and carbon markets. Direct collaboration with product, design, and stakeholders.

Growth: You'll shape technical architecture on greenfield projects like our digital twin system, influence technical direction, and have the opportunity to grow into technical leadership as we scale the team.

Our values

Measurably good for forests - What we do has a positive, data-driven impact on forests. We prove this through rigorous, transparent data that gives everyone confidence we're making the right decisions.

Location: Baltic region or Nordics preferred (our office is in Tallinn)
Work arrangement: Flexible remote work with occasional team days in Tallinn
Compensation: Competitive salary + meaningful equity, health and learning budget
Start date: Flexible, ideally Q1 2026

Our tech stack
