Jobs Fullstack

About us

We're an established direct-response e-commerce operation processing company. We're now building WasabiCRM — our own order-management and payments CRM, purpose-built for high-volume direct-response commerce. Rather than bending a bloated, general-purpose platform to our needs, we're building a lean, vertical system around the workflows that actually move revenue: checkout, upsells, subscriptions, decline recovery, and payment orchestration.

This is a rare chance to build a payments-grade product from the core outward, with real transaction volume flowing through it from week one — not a prototype looking for users.

The mission

Replace the legacy CRM the business runs on today with a system we own end-to-end: faster, cleaner, and built exactly for how modern e-commerce operators sell. Stage one is a focused internal platform that processes live orders through our payment integrations. From there, it becomes the central system our whole team runs on — and, ultimately, a product we open to external partners. You'll be one of the first engineers on this and will have direct influence over architecture, stack, and product direction.

What you'll build

• Checkout & funnel engine — high-converting, embeddable checkouts with order bumps, one-click upsells/downsells, and A/B testing
• Payments layer — integrations with payment processors and gateways (charges, tokenization/card-on-file, refunds, webhooks), plus transaction logging modeled as immutable events
• Subscription & rebill engine — recurring billing with dunning, smart retries, and decline recovery
• Orders, customers & reporting — a clean order/customer data model, a real-time operator dashboard, and by-product performance reporting
• Integrations — processors, fulfillment (ShipStation/3PL), email/SMS, and tracking/attribution via webhooks and postbacks

• Data migration tooling — reliable import of orders, subscriptions, and customer records from other CRMs

   

What you'll own

• Ship production features on a fast, iterative cadence with real revenue on the line
• Design a data model and API built to scale from internal use to a multi-tenant product
• Integrate third-party APIs cleanly (payments, fulfillment, messaging) with robust webhook handling, retries, and reconciliation
• Build for reliability: this system handles money, so correctness, idempotency, and auditability matter more than moving fast and breaking things
• Provide input into frontend development to design a beyond industry standard UI/UX

• Collaborate directly with the founders and a non-technical product owner — explain trade-offs in plain terms and demo working software every week

   

Required experience

• 2+ years building and shipping full-stack web applications end-to-end
• Strong TypeScript/JavaScript with React and Next.js
• Solid Node.js backend experience and comfort designing REST APIs
• Supabase is a must — hands-on experience building on it in production (Postgres schema design, Row-Level Security, Auth, storage, and realtime)
• Hands-on experience integrating third-party APIs and webhooks — ideally including a payment provider (Stripe, or similar)
• Deployment and ops on modern infrastructure (Vercel, plus AWS or equivalent)
• Understanding of authentication, authorization, and secure handling of sensitive data

• Fluent written and spoken English, and the self-direction to own features without hand-holding

   

Bonus points

• Direct experience with subscription/recurring-billing systems (dunning, retries, churn/decline recovery)
• Familiarity with payment concepts — gateways, merchant accounts (MIDs), tokenization, chargebacks, PCI scope
• Experience with e-commerce or CRM/order-management platforms (Shopify, CheckoutChamp/Konnektive, Sticky.io, Recharge, or similar)
• Multi-tenant SaaS architecture experience

• A track record of taking a product from zero to production

   

What we offer

• A greenfield build with real usage from day one and genuine ownership of the architecture
• A small, senior team that ships fast and makes decisions quickly — no bureaucracy
• Competitive compensation, remote flexibility, and room to grow into a lead role as the team scales

We are looking for an experienced Full-Stack developer with strong frontend expertise and comfort working on the backend. Most of the product's traffic comes from organic search, and conversion depends directly on page speed and UX quality, so this role is not just about writing code, but understanding how technical decisions affect business metrics. The split is roughly 70% frontend / 30% backend.

About the project: A ticket search engine for live events that lets users compare offers from multiple sellers in a single platform.

Qualifications: 
● 4+ years of full-stack experience with a clear frontend weight.
● Expert-level Next.js: App Router, React Server Components, caching strategies, SSR/ISR trade-offs. 
● Working Python for backend tasks: REST APIs, data modeling, third-party integrations, etc. 
● Proven track record of measurably improving Core Web Vitals on a real high-traffic product. 
● Strong CSS and UI craft. 
● Experience working autonomously in an async remote team.
● Fluent English, written and spoken.

Nice to have: 
● Background in marketplace / e-commerce / travel / ticketing products. 
● Experience with Elasticsearch, or building search-heavy products more broadly.
● Experience with multi-locale / multi-currency sites.

What you'll be doing: 
● Building and evolving product features in Next.js / React / TypeScript - event pages, search, ticket comparison, checkout handoff. 
● Directly owning Core Web Vitals and TTFB on high-traffic pages. 
● Treating technical SEO as an engineering problem: rendering strategy, structured data, i18n across dozens of countries. 
● Extending backend services and APIs in Python and Node.js that normalize inventory data from dozens of sellers. 
● Working closely with product managers, designers, and other developers.

This is NOT a traditional developer role.
We’re not looking for someone who writes code all day — we’re looking for someone who leads AI agents that write code for you.

This is not “a regular dev job with an AI assistant”.
This is a role for a person who thinks in systems, prompts, and outcomes, not in endless manual coding.

About us

We are a group of companies with 30+ active projects across travel, fintech, mobile apps, and AI products.
We build products through AI agents, and we’re looking for someone who knows how to work with them effectively.

Tech stack:

What you’ll do

• Translate product and technical ideas into clear tasks for AI agents
• Guide AI agents to produce production-ready code
• Review, refine, and improve AI-generated code
• Choose the right models and tools for each task
• Push features all the way to production

In short: you manage an AI-powered dev team that writes code for you.

What we’re looking for

• 1+ year of web development experience
• 3+ months of hands-on work with AI coding tools
• Experience working with AI agents (not just autocomplete)
• Ability to read code and do code reviews
• Solid understanding of frontend, backend, and APIs
• Advanced English

Nice to have

• Built projects mostly or fully using AI
• Know how to optimize AI usage for cost and limits
• Actively follow new models and AI dev tools
• Experience with mobile development

What we offer

• 🏢 Office-based role in Warsaw
• 🤖 Unlimited access to top-tier AI models
• 🎯 Direct collaboration with the CTO — no bureaucracy

How to apply

Please include:

• Examples of projects you built using AI
• Your AI setup: tools you use and how you handle limits and costs
• If you’ve only worked with Cursor — what doesn’t work for you in it?

🚀 If you want to build fast, experiment, and shape how products are created with AI — we’d love to hear from you.

Remote | Full-time | $2,000–3,000/month

We are looking for a Middle / Strong Middle Full-Stack Developer to join a newly forming technical team responsible for maintaining and developing existing CRM and web-based trading platform products.

The systems are already in production and used across multiple environments.

At the current stage, the majority of development work involves investigating and fixing existing issues, with additional product improvements and new functionality being introduced continuously.

This is not a role where every task comes with detailed technical implementation instructions.

We are looking for a developer who can gradually take ownership of issues and independently move from problem reproduction to root-cause analysis and implementation.

Previous experience in FinTech, Forex, CFD, or trading is not required. Product and business logic will be explained during onboarding.

What you will work with

The product environment includes:

• Web-based CRM
• Web-based CFD/trading platform
• Existing production codebase
• JavaScript-based web applications
• REST APIs
• WebSockets and real-time functionality
• Third-party integrations
• Multiple production environments
• GitHub-based development workflow

The existing codebase is complex and contains legacy functionality, so the ability to understand and debug unfamiliar code is important.

Responsibilities

• Investigate and fix bugs in existing CRM and trading platform functionality
• Reproduce reported issues using provided scenarios and production/test data
• Analyze application behavior and determine the actual root cause of problems
• Work with frontend and backend code
• Debug REST API and WebSocket-related issues
• Work with real-time application functionality
• Implement improvements and new functionality
• Work with third-party API integrations
• Read and analyze application and server logs when required for debugging
• Test your own changes before handing them over to QA
• Work closely with QA and DevOps
• Maintain existing functionality while implementing fixes to avoid regressions
• Work with Git/GitHub as part of the development process
• Document important technical implementations and changes when necessary
• Gradually develop a strong understanding of the system architecture and product logic

Expected workflow

For most technical issues, we expect the developer to gradually become capable of owning the complete development cycle:

Issue → Reproduce → Investigate → Identify root cause → Implement fix → Self-test → QA verification → Release

During onboarding, assistance will be provided with the existing codebase, product architecture, and trading-specific logic.

After onboarding, we expect increasing technical independence.

Requirements

• 3+ years of commercial Full-Stack development experience
• Strong JavaScript/web development fundamentals
• Commercial frontend and backend development experience
• Experience working with existing production applications
• Experience debugging complex application issues
• Experience with REST APIs
• Experience with WebSockets or other real-time functionality
• Experience with third-party API integrations
• Understanding of client-server architecture
• Ability to analyze application logs and technical errors
• Git/GitHub experience
• Ability to understand and work with an unfamiliar/legacy codebase
• Ability to identify root causes instead of applying temporary surface-level fixes
• Ability to test your own changes before passing them to QA
• English — Intermediate or higher

Experience with Node.js and modern JavaScript frontend frameworks is highly relevant to our environment.

Exact product architecture and existing implementation will be introduced during technical onboarding.

Trading experience

Previous Forex, CFD, brokerage, or FinTech experience is not required.

We will explain the required business logic, including concepts related to:

• Trading accounts
• Orders and positions
• Prices
• P&L
• Margin
• Leverage
• Trading symbols
• CRM workflows

We care more about your ability to understand complex systems and learn new domain logic than previous trading experience.

What we expect during the first months

The first 1–3 months will include technical and product onboarding.

The existing product is complex, and we do not expect a new developer to understand the entire system immediately.

After approximately three months, we expect you to:

• Understand the core architecture and product functionality
• Navigate the existing codebase confidently
• Reproduce and investigate issues independently
• Understand dependencies between CRM, trading platform, APIs, and real-time functionality
• Require significantly less guidance for standard bugs
• Take ownership of assigned technical issues
• Communicate clearly with QA, DevOps, and the Project Manager

Deployment

Production infrastructure and deployment processes are primarily owned by DevOps.

Developers are expected to understand the release process and cooperate closely with DevOps during deployment and troubleshooting.

Working conditions

• Fully remote
• Full-time
• Monday–Friday
• Working hours: 09:00–18:00 GMT+3 / 10:00–19:00 GMT+4
• No regular night/weekend on-call requirement
• Probation/onboarding period: 1–3 months
• Compensation: $2,000–3,000/month, depending on technical level and experience
• Long-term cooperation
• English: Intermediate or higher

What is important to us

We value developers who:

• Are available and responsive during agreed working hours
• Communicate when they are blocked instead of disappearing
• Notify the team in advance about planned absence
• Take responsibility for their work
• Investigate problems before asking for step-by-step instructions
• Verify their own fixes
• Consider the impact of a change on existing functionality
• Communicate technical problems clearly
• Are comfortable saying when they do not know something and then investigating it

We are building a new technical team around an existing production product, so reliability, ownership, communication, and the ability to become independent are as important as writing code.

Workflow

We take a leap, we make it big

We’re looking for a Senior Full-Stack Engineer / System Architect for a Vienna-based SaaS company on a mission to help organizations unleash their leadership potential — through digital feedback workflows, OKRs, mentoring, and people analytics that support managers at every level. 

The Role

We're hiring a hands-on Full Stack System Architect to lead architecture for our enterprise AI SaaS platform — spanning Angular, TypeScript, Python, Node.js, cloud infrastructure, and AI/LLM integration. The product combines agentic AI workflows with precision AI tools for people analytics, leadership development, and performance management.

This is not a management role. Our six-person remote team (four full-time, spanning Austria and India) is close-knit, well-organized, and doesn't need another layer of hierarchy. We need a technical peer — a "shark in the pond" — senior enough to challenge, mentor, and upskill the team through hands-on delivery, not authority.

What You'll Do

• Own system architecture for a scalable, enterprise-grade AI SaaS platform
• Architect across the stack: Angular/TypeScript frontend, Python/Node.js backend
• Design and ship AI/LLM integrations in production, including agentic workflows
• Take direct ownership of project streams and sprints
• Expand the team's use of AI-assisted tooling (we currently use Claude for coding and design)
• Mentor and gently challenge the team, raising standards without disrupting trust
• Manage infrastructure: cloud, CI/CD, Docker, Kubernetes, Terraform

What We're Looking For

• Proven scalable SaaS system architecture experience
• Strong Angular + TypeScript and Python + Node.js expertise
• Track record integrating AI/LLMs into production
• Solid cloud, CI/CD, Docker, Kubernetes, Terraform skills
• Strong technical leadership with genuine hands-on delivery — a senior IC, not a manager
• A collaborator who values cultural fit and trust, and can integrate into an established remote team rather than restructure it
• Nice-to-have: HR-tech / people-analytics domain experience; experience mentoring engineers remotely

Practical Details

• Full-time, flexible start 7:00–10:00 AM Vienna time
• Fully remote — anywhere in Europe or safe zones in Ukraine
• Full GDPR compliance, VPN and two-factor authentication required
• Joining a 6-person engineering team led by a strong 26-year-old lead engineer

Equal opportunity — we welcome applicants of all genders and backgrounds; our engineering team is currently male-dominated and we're working to change that.

We're an IT outstaffing agency, and we're urgently looking for a Senior Full-Stack Developer to join a project for our client in the USA. This is a backend-leaning full-stack role - you'll be building AI-powered features end-to-end, from data pipelines to polished UI.

About the role: You'll work on a product that leverages AI APIs, vector search, and RAG, building both the backend infrastructure and the frontend that surfaces it. We need someone who can own a feature end-to-end and move fast.
