Jobs Golang

MOR.AI is building the next generation of payment infrastructure — a Merchant of Record platform and a network of PayFacs.

We’re looking for our first technical hire — someone who can take the product from 0 → 1, build the platform from scratch, and eventually grow into a CTO role.

This is not a corporate job. You’ll own the architecture, infrastructure and delivery from day one.

What you’ll do

• Architect and build the entire V1 platform from scratch in Go
• Own backend, APIs, infrastructure and complex billing systems
• Design and build MoR / PayFac architecture
• Work hands-on with payment infrastructure, acquirer integrations and card network rules
• Make key technical decisions and move fast
• Build and lead the engineering team as the company scales
• Take ownership of the technical function as the company grows

What we’re looking for

Payments experience is mandatory. We’re looking for someone with hands-on experience in payment infrastructure and payment systems, including PayFacs, acquirers and card networks.

You should:

• Have strong backend engineering experience with Go / Golang
• Be able to independently architect and build a V1 product
• Be comfortable being the only developer for an extended period
• Have hands-on experience with payments
• Understand payment infrastructure, billing systems and MoR / PayFac architecture
• Think like a founder, not a corporate employee
• Be highly hands-on, fast and execution-oriented
• Be AI-native and use tools such as Cursor, Copilot, Claude, etc. to significantly accelerate development
• Have the ambition to build and lead an engineering team

The opportunity

• Base salary: market or below-market
• Significant % of EBITDA — real profit sharing, not just illiquid equity
• Clear, performance-based path to CTO
• Become the first technical hire and have real ownership from day one

If you’re looking for a comfortable corporate role, this is probably not for you.

If you want to build something from the ground up, shape the architecture, build the team and participate directly in the profits — let’s talk.

Hiring process

1. CV + relevant experience review
2. Initial screening
3. Culture alignment
4. Technical deep dive + architecture review
5. Final interview with the Founder

We are looking for an AI-First Golang Team Lead for one of our product engineering pods: a hands-on engineer who uses AI to ship fast and acts as the face of their pod towards clients and leadership.

⚠️IMPORTANT: This is not a traditional coding role. You’ll use Claude Code and other AI tools to 10x your output, always thinking about how the product or feature you are working on benefits the user. Also: we have no QA team, you OWN the quality of what you ship!

🧭About this role: every engineer on the team already owns their work end-to-end (IC + DRI). Everyone in the pod is, in effect, their own architect and lead developer. So this role is not about being the strongest techie in the room or telling people how to build.

A Team Lead is the spokesperson, coordinator, and facilitator for their pod, internally with product, design, and leadership, and externally with clients. You come from the management path, not the deep-specialist path: you have seen a lot as a developer and have consciously decided that enabling a team, working with clients and driving product outcomes is what energizes you now, not coding all day.

You remain a hands-on engineer. Expect roughly 30-40% of your week on coordination, client and product work, and the rest as an individual contributor. This is not an HR-style people-management role: no performance reviews, no career coaching. As we scale, light one-on-ones and check-ins may become part of it, but the job is coordination and delivery, not administration.

🧑 💻 What you’ll actually do:

• Be the spokesperson for your pod, internally with product, design, and leadership, and externally with clients and partners.
• Coordinate work across the pod: break initiatives into chunks, sequence them, surface blockers, and facilitate hand-offs (lightweight project management; we deliberately have no project managers).
• Gather client requirements first-hand and funnel them straight into the pod so nothing gets lost in translation.
• Represent your pod in product planning sessions and bring a strong product-driven point of view to scoping and trade-offs.
• Help pod members with product decisions and prioritization, enabling engineers who may be technically stronger than you.
• Contribute hands-on as an engineer: own features end-to-end, use Claude Code to generate Golang backend code, review AI output for quality and architectural fit.
• Join client meetings to align on requirements, report on delivery, and keep the relationship professional and calm.

📚 Our stack:

• Backend: Go monorepo (no framework, 3+ services).
• Hosting: PaaS-managed containers; local setup fully mirrors production via Docker Compose.
• Tools: Jaeger tracing, Betterstack (Logging, Alerting), Redis Asynq queue.
• Databases: PostgreSQL, Redis.
• AI tooling: Claude Code (mandatory).

🚢 Products you will lead a pod on:

• An AI search & recommendation engine for major travel enterprises: heavy client integration work (SSO, security reviews, GDS integrations) with demanding enterprise customers.
• A content enrichment API: high-scale, data- and AI-focused backend work.
• Partner and supplier integrations, data ingestion pipelines, LLM providers.

✅ You must have:

• 2-3+ years of technical leadership experience leading a team, squad, pod, or similar unit (a hard must; think team lead or early-stage engineering manager).
• A developer’s background (minimum 5 years): you have seen production reality with your own hands before moving towards leading people.
• A genuinely product-driven mindset: you think about user value and business outcomes before implementation.
• Comfort facilitating and coordinating a pod without relying on formal authority.
• Willingness and ability to take part in client meetings and act as the external face of your pod.
• Excellent spoken and written English for planning sessions, stakeholder updates, and client conversations.
• Ownership mentality with a strive for elegantly simple, high-quality solutions; you test your own work thoroughly since we have no QA team.
• Proven experience using Claude Code; share specific examples.
• Solid Golang experience; you’ll review AI’s code, and you must understand how it works.
• Ability to do on-call once in a while to help maintain our platform’s reliability & uptime.
• ⚠️ European or African timezones (±3 hours from CET).
• Available full-time (40 hours/week).

❤️ You are a great fit if you:

• Made the classic developer’s fork-in-the-road decision: lifelong engineer or leading people, and chose people, clients, and product.
• Are energized by product planning sessions and have opinions about what the pod should build next, not just how.
• Are comfortable being the face of your pod, in internal planning rooms and on calls with enterprise clients.
• Enjoy enabling engineers who are technically stronger than you.
• Ship fast but always verify it actually works; think “how can AI build this?” as your first instinct.
• Get frustrated when development takes weeks instead of days.

‼️Things to consider before applying that won’t be a match:

• This would be your first leadership role.
• You see the lead as the chief architect who makes the technical decisions for the team.
• You are looking for an HR-focused people-management role built around performance reviews and career coaching.
• You want to lead a team without staying hands-on in the codebase.
• You would rather not take part in client meetings or stakeholder-facing conversations.
• You prefer to focus on execution and leave product planning to others.
• You rely on formal authority to get a team moving.
• You have never used Claude Code or similar AI coding tools.
• You are outside European/African timezones.

What this is about
 

We are a fast-growing software house looking for a mid-level GoLang Software Engineer to join a fully remote team.

Your main focus will be the backend: designing and building reliable services, APIs, and data flows, improving the architecture and performance of our platform, and turning product requirements into robust systems that users rely on every day.

At the same time, you will not work in isolation from the rest of the stack. You will collaborate closely with the frontend and infrastructure side, and when needed you may also touch deployment, databases, and other parts of the platform. We value engineers who understand how the product works end to end, even if their strongest area is backend.

If you enjoy building clean, maintainable systems, solving complex technical problems, and care about reliability, performance, and good software architecture, this position is for you.
 

How we think about AI
 

AI coding tools are part of our daily work, and we want them to be part of yours too. For us, they are a great way to:

• write faster the parts you already understand, while always reviewing, validating, and correcting what they produce
• reason through problems and test new solutions
• learn something new along the way

What we are not looking for is someone who pastes output they would not be able to understand or explain.

The tool speeds up the work, but your brain must remain the one making the decisions.
 

What you will do
 

• Develop and release new backend features from start to finish
• Design, build, and maintain reliable services and APIs in Go
• Work with databases, queues, caches, and other backend infrastructure
• Improve the performance, scalability, and reliability of existing services
• Collaborate closely with frontend and infrastructure engineers
• Write clean, well-tested, maintainable, and production-ready code
• Debug and troubleshoot issues across distributed systems
• Work with different stakeholders in an async-first environment
   

Who we are looking for

• At least 2 years of experience as a software engineer, preferably with a strong backend focus
• Experience with Go (Golang) is required
• Good understanding of backend development, REST APIs, databases, concurrency, distributed systems, and service-oriented architecture
• Familiarity with SQL and working with relational databases
• Ability to write clean, maintainable, and well-tested production code
• Comfortable debugging issues and reasoning about performance and reliability
• Independent thinking: AI is a tool, not a shortcut to avoid thinking
   

What we offer

• Fully remote work from anywhere in the European time zone
• Flexible hours, async-first culture, zero micromanagement
• Location-based benefits, where applicable
