## Job description

Backend Engineer 🌍 About Outpost What if going global was as simple as going local? Outpost is building the AI global trade engine. The accumulated knowledge of every rule you'd need to sell internationally, turned into infrastructure. Tell us what you're selling. We'll tell you how to sell it everywhere. We operate as Merchant of Record or Tax of Record across 58+ tax jurisdictions. Full liability transfer, or just the tax layer. We do the analysis, we handle the setup, we absorb the liability. Sell anything, anywhere. Without compromise.

🧠 The Role This is a Backend Engineer role for someone who wants to build complex financial infrastructure from scratch. You'll work directly with our engineering leadership to implement payment flows, build tax calculation engines, and create the systems that power international commerce. You'll contribute to product and technical discussions, challenge assumptions, and help guide our technical direction. We're building the infrastructure that lets businesses sell globally without the usual pain. That means payment processing, multi-currency ledgers, real-time tax calculations, merchant onboarding, and AI-powered compliance tools. Hard problems with real scale.

🧗 What You'll Get Yes, the work is intense. But in return, you'll build critical financial infrastructure that handles hundreds of millions in volume. You'll have significant input into technical direction, work with a small team of experienced engineers, and shape how Outpost scales. If you want to go deep on payments, tax, and fintech infrastructure, this is the role.

🧩 What You'll Build

- Payment processing infrastructure handling hundreds of millions in volume
- Robust ledger and reconciliation systems
- Tax calculation engines for multiple jurisdictions
- Real-time transaction monitoring and risk systems
- Merchant onboarding and integration frameworks
- Platform connections with major e-commerce systems
- AI/LLM powered taxation tools
- AI/LLM powered fraud and risk tools

🧩 What You'll Do Technical Development

- Write high-quality, maintainable code
- Implement core payment and financial systems
- Build secure, scalable backend services
- Contribute to system architecture discussions
- Help establish engineering best practices

System Design & Implementation

- Design and build robust payment processing flows
- Implement internal ledger and reconciliation systems
- Create merchant integration frameworks
- Develop automated monitoring and alerting
- Handle secure financial data processing

Cross-functional Collaboration

- Work with product team to refine technical requirements
- Contribute to API design and implementation
- Collaborate with risk and compliance on system requirements

💥 Example Projects

- Implement a multi-currency ledger that handles real-time reconciliation
- Create the tax calculation engine for a new jurisdiction
- Design the merchant onboarding flow and integration framework
- Build AI-powered tools for automated tax classification
- Implement real-time fraud detection and risk scoring
- Create automated reconciliation systems that catch discrepancies before they become problems

🧱 What We're Looking For Ideal background:

- Fluency in a JVM-based language, preferably Kotlin
- Track record of implementing complex backend systems
- Strong engineering fundamentals and coding practices
- Bonus: experience building financial, payments, tax, or compliance systems
- Bonus: familiarity with e-commerce platforms

Signals we care about:

- You write high-quality code and care about maintainability
- You can design systems, not just implement them
- You're comfortable with ambiguity and figuring things out
- You contribute to technical discussions and challenge assumptions
- You want to build from scratch, not maintain existing systems
- Bias for action. You ship, you learn, you iterate

What this role is not:

- Not maintaining existing systems. You'll build from scratch
- Not a role where you wait to be told what to do
- Not someone who needs heavy process or detailed specs to be effective
- Not pure execution without input into technical direction

🚀 Why This Role Is Different Most backend roles are about maintaining or extending existing systems. This role is about building complex financial infrastructure from the ground up. You'll tackle challenges like managing multiple currency ledgers, handling card payment flows, building automated reconciliation systems, and creating AI-powered tax tools. You'll have significant input into our technical direction. If you're excited about building complex payment systems and want to shape the future of international commerce, this is the role.

🦾 Outpost Team Our team were leaders at Revolut, Airwallex, Adyen and Wayflyer, and we're backed by top-tier investors who have built or backed some of the world's leading fintechs.

🧾 What We Offer

- Equity and salary in a well-funded startup
- Ability to own your work and move fast
- Direct access to the founding team
- A global mission with real impact
- Low politics, high output
- A culture of builders, not talkers

🧭 Working Style We work together in person in London. We believe the hardest problems are solved in the room.

## About Outpost Technologies

## Company Overview
- **One-liner**: Outpost provides global commerce infrastructure, acting as a legally liable Merchant of Record, Tax of Record, and Importer of Record to let businesses sell anywhere without managing local entities.
- **Entity Type**: Private (funding stage not publicly available)
- **Headquarters**: London, England (with offices in Amsterdam, Netherlands, and New York opening soon)
- **Founded**: 2024
- **Founders**: Not publicly available

## Core Business
- **Primary industry**: Cross-border payments, tax compliance, and logistics infrastructure for e-commerce and B2B.
- **Target customers**: B2B – merchants, marketplaces, and any business selling internationally (enterprise and high-growth SMB).
- **Mission or purpose**: “Making business borderless” – Outpost takes on legal liability for taxes, customs, and payments so clients can focus on growth.

## Products & Services
- **Merchant of Record (MoR)**: Outpost becomes the legal seller in local markets, enabling local acquiring (boosts approval rates 10‑15%), like‑for‑like FX settlement, and access to local payment methods. Works alongside any PSP.
- **Tax of Record (ToR)**: Outpost registers, calculates, files, remits indirect taxes across 58+ jurisdictions and handles audit notices. The company owns the full tax liability.
- **Importer of Record (IoR)**: Handles customs declarations, duty calculations, import VAT, and goods classification (AI‑powered HS code). Essential for EU/UK shipments after the July 2026 de minimis removal.
- **B2B Invoicing**: Outpost becomes the local seller for cross‑border B2B transactions, issuing compliant invoices and remitting proceeds, reducing withholding tax (e.g., up to 40% in Brazil).

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Customers process over $1 billion annually through Outpost (company revenue not publicly available).
- **Notable Investors/Partners**: Not publicly disclosed; team background includes builders from Revolut, Adyen, and Airwallex.
- **Growth Signals**: Offices in London and Amsterdam, New York opening soon; serves 58+ jurisdictions; claims average revenue increase of $500k and 25‑40% improvement in payment approval rates for clients.

## Competitive Advantages
- **Liability‑based model**: Unlike tax software (e.g., Avalara, Vertex), Outpost takes the full legal and financial liability for taxes, customs, and fines – not just software.
- **Full‑stack infrastructure**: Combines Merchant of Record, Tax of Record, and Importer of Record in one API, with the ability to work alongside existing PSPs and logistics providers.
- **AI‑powered classification**: Automated HS code classification for customs, reducing manual effort and errors.
- **Scalable and isolated**: Each client gets its own legal entity, avoiding contamination from other merchants’ risk or audits.

## Strategic Focus
- **Global expansion**: Adding new markets (LATAM, APAC, USA) and preparing for EU de minimis changes in July 2026.
- **Deepening the infrastructure layer**: Continuing to own more of the cross‑border compliance stack (payments, tax, customs) to simplify international selling.
- **Talent acquisition**: Hiring aggressively in London, Amsterdam, and soon New York for engineering, strategy & operations, legal, and marketing roles.

## Why Work Here
- **Culture**: Described as built on trust, collaboration, and common decency; they challenge ideas and are open to being challenged. Values include a “ridiculous bias for action,” strong EQ, extreme hard work, and comfort with ambiguity.
- **Work environment**: In‑office (London, Amsterdam) with full sponsorship for international hires; New York office opening soon.
- **Team**: Composed of talent from top fintech brands (Revolut, Adyen, Airwallex) – an opportunity to work with experienced operators.
- **Impact**: Directly shaping the infrastructure for global commerce; roles involve building scrappy systems and solving hard problems at scale.
