Project: UK-based Financial Services digital transformation. Building and scaling high-performance web applications and internal platforms using a modern Microsoft ecosystem. The role involves developing user-centric front-end interfaces and robust, cloud-native backend services.
List of Duties:
- Design and implement end-to-end features from UI components to backend APIs.
- Optimize applications for maximum speed, scalability, and security.

Requirements:
- 5+ years of professional experience in Full Stack development.
- Proficiency in .NET (C#) and React with TypeScript.
- Experience with ASP.NET Core for building RESTful APIs and Microservices.
- Hands-on experience with Azure Kubernetes Service (AKS) and Docker.
- Proficiency in State Management (Redux, Context API) and modern Hooks.
- Solid understanding of SQL Server and Entity Framework Core.

You'll build features, fix bugs, and grow your skills across our Azure-based platform. You'll work alongside senior developers who'll support your development while expecting increasing independence over time.

Required:

• 2–4 years of professional experience with C# / .NET (Core/.NET 6+)
• Working experience with Azure services (Function Apps, App Services, Key Vault, Blob Storage — at least some)
• Solid SQL Server fundamentals (queries, stored procedures, basic EF Core or Dapper usage)
• REST API development experience
• Familiarity with Git, pull requests, and code review workflows
• Willingness to learn new Azure services, patterns, and tools as needed
• Good communication skills and comfort asking questions

Preferred:

• Angular or other modern frontend framework experience
• Azure Logic Apps or Power Automate exposure
• CI/CD pipeline exposure (GitHub Actions, Azure DevOps Pipelines)
• Basic Azure networking understanding (VNets, app settings, managed identity)
• Experience with structured logging and Application Insights

• Contribute to CI/CD pipelines, deployment processes, and documentation
• Grow toward owning features end-to-end as you gain experience with the platform

Our client is an Ad Tech SaaS on Shopify that helps e-commerce businesses run profitable ads on Meta and Google. Our product vision: an AI agent that manages ad spend, optimizes ROAS, and delivers results — so merchants can focus on their business, not their ad accounts.

We're looking for a senior engineer to take real ownership of the product and help us ship the next version of the platform — not as a ticket-taker, but as the technical co-owner of what we build and how we build it.

What you'll own

• AI-assisted development infrastructure. You'll own the system that lets our team ship fast with AI. That means: expanding our CLAUDE.md with real coding conventions, building Claude Code skills and hooks, setting up CI quality gates (linting, formatting, automated tests), and creating the pre-merge workflow so AI-generated PRs pass review on the first try. This is your highest-impact work in the first month.
• AI-native product experience. Store intelligence that analyzes a merchant's data, scores products by predicted ROAS, and drives every recommendation the platform makes.
• Shopify-deep integration. Adwisely should live where merchants already work: Shopify admin, Sidekick, Flow — not as a separate dashboard they forget about.
• Platform reliability and UX improvements. Bulletproof onboarding, ROAS optimisation, clearer performance visibility.

• Quality at every stage. You own QA as part of the delivery process, not as an afterthought. That means writing specs that include test cases, reviewing AI-generated diffs for correctness, and building end-to-end tests for critical paths.

   

How we work

We build with AI-assisted development. Our primary tool is Claude Code with a custom CLAUDE.md, project-specific skills, and pre-commit hooks. You'll extend and improve this setup.

The workflow is: write a tight spec, generate an implementation plan (reviewed by you before coding starts), generate the implementation with Claude Code, pass automated quality gates, and ship. You'll be the person who makes this workflow reliable — so that PMs can independently deliver features at high quality.

You'll work directly with the company founders. No PM layer, no sprint ceremonies. Team: 2 PMs, 1 senior dev, 1 part-time dev. Small team, high ownership, no bureaucracy.

This role is for you if...

• You have 5+ years with Python and React in production
• You have hands-on experience with AWS: EC2, RDS, S3, Lambda, or similar services
• You're comfortable owning the full stack: React frontend, Python backend, cloud infrastructure
• You've worked with at least one of: Shopify APIs, Meta Marketing API, Google Ads API
• You're used to being the primary engineer and making architectural calls without a lot of hand-holding
• You can move between support and feature work without losing momentum
• You've used Claude Code, Cursor, or Copilot in production — and you have opinions about where AI helps and where it doesn't
• You treat QA as part of shipping, not a separate phase. You write tests, review diffs carefully, and don't merge what you haven't verified

• You're excited about building the dev process itself, not just building features within one

   

Nice to have

• Experience building or maintaining Shopify apps (ours is built on Remix)
• Familiarity with LLM API integration (Anthropic, OpenAI, Gemini)
• Any background in ad tech or performance marketing

• Experience setting up CI/CD pipelines, automated testing, or developer tooling

   

What we offer

• $4,500-6,000/month depending on experience
• Equity stake with vesting — you're joining as the primary engineer at a pivotal moment (details in offer conversation)
• Architecture ownership: meaningful decisions, not just tickets
• Greenfield opportunity to shape how the entire engineering org works
• Fully remote, flexible schedule
• Paid vacation

Truffle (hiretruffle.com) — AI-powered candidate screening platform, used by hundreds of companies. Small team, real product, contract to start with intention for extending to full time, fully remote.

WHO WE'RE LOOKING FOR

A backend developer to own two surfaces that move our revenue: Stripe (subscriptions, metered billing, webhooks, dunning) and ATS/HRIS integrations (Ashby is live, you'd lead the next 3–5).

CLAUDE CODE IS REQUIRED — DAILY

We're an AI-native team. Our engineering workflow is built around Claude Code (or Cursor). We're not looking for someone willing to try it — we need someone who already builds this way every day. This is the most important part of the role.

THE STACK

- PHP (Slim v4), MySQL, REST APIs, background workers
- Stripe — subscriptions, metered billing, webhooks, reconciliation
- AWS (ECS/Fargate, S3, CloudWatch), Docker, GitHub Actions
- TypeScript / React when a payments flow needs it (backend-weighted role)

WHAT YOU'LL OWN

- Stripe end-to-end — the boring-but-critical reliability work payments live or die by
- ATS/HRIS adapters on our 3-layer integration architecture
- Event infrastructure (the bus powering PostHog + Attio sync)
- Backend product work — APIs, business logic, data models

YOU'RE THE FIT IF

- You use Claude Code or Cursor every single day
- You've shipped real Stripe — webhook idempotency, proration, failed payments, subscription state machines (not just Checkout)
- You've built B2B integrations real customers depended on
- You can operate AWS in prod without panicking
- You're independent — take a spec, ship it, no handholding
- English: confident in writing and on calls (B2+)

NICE TO HAVE: ATS/HRIS experience, event-driven architectures, startup background.

WHAT WE OFFER
- Fully remote, async-first
- 3-month contract, strong intent to extend
- High ownership, direct access to founders, no bureaucracy

HIRING PROCESS

Short async screen (3 video questions, ~10 min) → 30-min technical conversation → paid micro-project (real Stripe or integration task, ~3 hours, compensated) → optional 2-week paid trial sprint.

We read every application. If you've shipped real Stripe and you build with Claude Code daily, we want to hear from you.

Project: 

A leading technology company that uses real-world data in real-time to optimize campaign performance and revolutionize health decision-making. Leveraging proprietary datasets and methodology, it targets healthcare professionals and patients with an unprecedented level of accuracy—delivering unparalleled results to the clients we serve.
