internal service boundaries.

• Write efficient, readable SQL for data retrieval, aggregation, and validation.

• Ensure the correctness of financial calculations and aggregations.

• Collaborate closely with:

o Product on requirements and edge cases.

o QA on testability and bug resolution.

o Other engineers on architecture and code quality.

• Review code and contribute to technical standards and best practices.

• Participate in release planning and production readiness.
 

Required Skills and Experience

• 5+ years of professional software engineering experience.

• Strong experience building fullstack web applications.

• Solid frontend experience with:

o React.

o TypeScript.

o Modern component-based UI patterns.

• Strong backend experience with Node.js-based API services, including business logic and data validation.

Strong SQL skills, including:

o Writing complex queries.

o Working with aggregations and joins.

o Reasoning about data correctness and performance.

• Experience working with relational databases. PostgreSQL is preferred.

• Comfort working in production systems with real users and data.

• Ability to reason about edge cases, failure modes, and data consistency.
 

Nice to Have

• Experience with financial, analytics, or reporting platforms.

• Experience working in early-stage or startup environments.

• Exposure to Python is a plus, although the core backend is implemented in Node.js.
 

What Success Looks Like in the First 90 Days

• You understand the platform’s data model and core product flows.

• You ship multiple production features end-to-end.

• Your code is readable, testable, and trusted by the team.

• You proactively surface edge cases and data issues.

• Product and QA rely on you for clarity and execution

Shopify App development, Shopify Functions and Checkout Extensions, Shopify Admin GraphQL API, ERP integrations, payment gateways, HubSpot API, Monday API, Meta API, GraphQL, BullMQ or RabbitMQ, SaaS product development, experience with AI APIs (OpenAI, Claude, Gemini), RAG, tool calling, or prompt engineering.
 

Who We're Looking For

Someone who doesn't just write code but understands business processes — able to take a real customer problem (inventory sync, complex checkout, ERP integration, business automation) and turn it into a stable, smart, maintainable solution.

Bonus if you've already built: SaaS systems, CRM systems, complex automations, Shopify Apps, Shopify Functions, system integrations, AI tools, ERP sync systems, backend infrastructure for business systems.
 

Soft Skills

Systems thinking and architectural planning ability, full end-to-end ownership of tasks, strong independent learning ability, proactive problem-solving, good communication with technical and non-technical teams, ability to work in a dynamic environment, willingness to work with AI tools like Cursor, Claude Code, or Codex as part of the dev process.
 

What You'll Build

From day one you'll work on systems in real use by leading eCommerce brands: Shopify Apps and Shopify Functions, subscription and billing systems, ERP and payment integrations, backend infrastructure for business systems, AI tools for automation and data analysis, sync engines and catalog enrichment.

About Us

We're building a B2B sales intelligence platform for international trade. Our software helps companies discover new buyers and suppliers worldwide and connect with the right decision-makers.

Most businesses struggle to find reliable partners abroad. We're making global trade accessible to everyone, not just large corporations with dedicated export sales / procurement teams.

We're a young and growing company with active clients using our platform daily. Our team is lean, 2 founders, a strong team of advisors, a lead developer, and we're looking for a full-stack developer and other roles to join us and help build the next biggest trade market intelligence platform in the world.

Role Description

We're looking for a freelance full-stack developer with a strong backend focus. You'll ship new features, solve real problems, and help shape the technical foundations of a product that's growing.

Today, one the founder handles the product and works with one technical lead. You'd be the second person on the tech side, a structuring role with real impact and direct input on key decisions.

You'll have full ownership of your work, from idea to production. That means making technical decisions yourself, validating your own features, and shipping with confidence. You won't be alone, you'll work closely with the technical lead and get support on architecture and complex decisions. But you'll still own your deliverables.

You will:

• Ship product features end-to-end
• Debug and resolve production issues (performance bottlenecks, race conditions, data inconsistencies)
• Own our third-party integrations
• Own background jobs & webhooks reliability (Inngest, retries, idempotency)
• Optimize PostgreSQL & ClickHouse queries for high-volume data (billions of rows)

Team & Working Environment

You'll join a very small team with few formal processes and a product that's still early-stage. This means strong autonomy and individual responsibility. You'll own problems end-to-end, make technical trade-offs on your own, and validate your work before shipping.

Day-to-day, you'll be working on a product that's already in production, used by real clients. That means debugging real incidents, making technical trade-offs without detailed specs, and iterating fast: ship, observe, improve. We have two daily syncs, one in the morning to align, one at end of day to review progress

Tech Stack

• Next.js 15 (API Routes, Server Actions, React)
• PostgreSQL + Supabase + ClickHouse
• Vercel, Inngest, Clerk
• TypeScript

Nice to Have

• Architecture experience: designing or restructuring systems at scale (not just building within one)
• Analytical/columnar databases (ClickHouse, BigQuery, DuckDB)
• Security: multi-tenant isolation, roles & permissions, secrets & data security (access scoping, encryption at rest/in transit)
• GDPR & data protection

Must Have

• 3+ years Node.js/TypeScript backend experience
• 3+ years building production systems with Next.js
• Strong PostgreSQL experience (transactions, performance, indexing, connection pooling)
• REST API design & security (auth, input validation, rate limiting)
• Experience stabilizing and refactoring existing codebases, not just greenfield
• Comfortable working across backend and the Next.js app layer

What are you looking for in a hire?

• Curious & Growth-Oriented: You stay up to date with new tools and frameworks, and actively seek opportunities to expand your skills
• Resourceful Problem-Solver: You take initiative when facing blockers and find solutions independently
• Strong Ownership Mindset: You care deeply about the end-user experience and aren't afraid to challenge decisions to improve the product
• Execution-Focused: You prioritize shipping and iterating over perfection
• Proactive Communicator: You keep the team informed, articulate ideas clearly, and ask for help when needed
• Agency: You don't wait for permission or perfect specs, you decide, act, and flag it.
• Flexible: Priorities shift fast, you switch from a data pipeline to a React fix without friction.

Why Working With Us?

• Real impact from day one: your code ships to production and is used by real clients immediately
• Learn fast: work directly with the founders on a product that's growing and evolving rapidly
• Ownership: you won't execute tickets, you'll own problems and solve them
• Early-stage opportunity: join at 6 months in, grow with the company as we scale
• Autonomy: you're trusted to make decisions and work independently, with guidance on priorities and people around to help when needed

• Contract: Freelance, with opportunity to convert to CDI (Contrat à Durée Indéterminée)
• Compensation: $3,000–$3,500/month
• Location: On-site in Paris preferred, open to full remote for other European locations (Full remote, CET±2)
• Engagement: Full-time
