Python Tech Lead for AI Marketing Startup
Full Remote · Countries of Europe or Ukraine · 10 years of experience · English - B2We are DevBrother, a forward-thinking technology company building the next generation of AI Agentic Marketing Solutions. We operate in a fast-paced startup environment where speed is a feature. We are moving beyond R&D into production, building autonomous...We are DevBrother, a forward-thinking technology company building the next generation of AI Agentic Marketing Solutions. We operate in a fast-paced startup environment where speed is a feature. We are moving beyond R&D into production, building autonomous agents that plan, execute, and optimize marketing campaigns.
We are looking for a Technical Lead who is ready to get their hands dirty immediately. You will partner with our current high-performance team to ship product features fast.
The Role: Builder First, Architect Second
This is not an "ivory tower" architecture role. You must be ready to contribute code from Day 1. We need a leader who thrives in ambiguity, makes rapid decisions, and balances "perfect architecture" with the startup reality of "shipping today."
You will act as the engine of our engineering team—transforming broad business goals into working software with minimal friction.
Key Responsibilities
1. Immediate Contribution & Velocity
- Ship Fast: You will code core features of the AI platform immediately. We expect deployments to happen daily, not monthly.
- Rapid Prototyping: Quickly build and iterate on Agentic workflows (using LangChain/LangGraph) to test product hypotheses. You know when to build an "MVP" and when to build "Enterprise Grade."
- Bias for Action: Eliminate analysis paralysis. You will make technical trade-offs quickly to keep the team moving forward.
2. Python-Centric Engineering
- Hands-On Coding: serve as the primary contributor to our Python codebase. You will write clean, asynchronous code (FastAPI, AsyncIO) that handles complex agent orchestration.
- Production AI: You won't just tweak prompts; you will build the serving infrastructure, vector retrieval pipelines (RAG), and evaluation loops that make our agents reliable in production.
3. Strategic Scalability
- Evolving Architecture: While you ship fast, you will ensure we don't code ourselves into a corner. You will design event-driven systems (NATS/Kafka) that allow us to scale 10x without a rewrite.
- Owner Mindset: This means caring about "Unit Economics" and "Cost of Delay" as much as code quality.
Requirements
The "Startup DNA"
- Readiness to Contribute: You are comfortable jumping into an existing codebase and pushing commits within your first week.
- Adaptability: You thrive in an environment where priorities can shift.
- Pragmatism: You understand that "Done" is better than "Perfect." You focus on business value over over-engineering.
Technical Expertise
- Python Mastery: Expert-level Python skills are non-negotiable. You know the ecosystem (Pydantic, Poetry, FastAPI) inside and out.
- AI Engineering: Experience building actual products with LLMs (not just tutorials). You understand the challenges of context windows, latency, and hallucination.
- Architecture background: 10+ years in engineering, with a track record of designing systems that survived rapid scaling. Experience with Microservices and Event-Driven Architecture.
- Infrastructure: Solid grasp of AWS and Kubernetes—you can fix a broken pipeline or deploy a container without waiting for a dedicated DevOps engineer.
What We Offer
- High Impact: No bureaucracy. Your code goes to production. Your decisions shape the company.
- Growth: A fast-track path to be a key person on the product.
- Culture: A team of senior experts who value "Delivery in 1 Second" and relentless improvement. We work hard, move fast, and measure results.

Fullstack React/Node developer (Ticketing and marketing solution)

We are engineering a custom, high-load platform from scratch. The ecosystem includes:
- Complex Web Platform: Handling Reserved Seating schemes, Camping bookings, and deep Event Management logic.
- On-Site Operations: Gate Scanning functionality and Ticket Printer control. We develop the scanning logic and integrate it with physical hardware for printing.
Mobile Ecosystem: A feature-rich mobile application for organizers and attendees.
We don't use "out-of-the-box" solutions. We build our own logic to handle heavy complexity. If you prefer solving technical puzzles rather than integrating standard plugins, this is your place.
⚠️ THE CULTURE (Read this first): We are a US-based startup in an aggressive growth phase. We are looking for a Founding Engineer mindset.
- Intensity: We work with the US market. Late evening calls (European time) are standard to sync with the founders.
- Ownership: You don't just "close tickets." You own the feature from the database architecture to the UI. If the Gate System goes down on a Saturday night during a festival, you are the one helping to fix it.
- No "Code Monkeys": We discuss business goals. You need to understand why we are building a feature. If a requirement doesn't make sense technically, we expect you to push back and propose a better solution.
Tech Stack: React, Remix, Tailwind UI, Node.js, NestJS, TypeScript, PostgreSQL (TypeORM), GCP infrastructure.
Requirements:
- 4+ years of engineering experience, with deep expertise in the Node.js/React ecosystem.
- Modern Stack Mastery: You are proficient with NestJS on the backend and React/Remix + Tailwind UI on the frontend.
- Architectural Grit: Experience building custom complex systems (booking engines, CRM, logistics). You know how to design database schemas (PostgreSQL/TypeORM) that won't break under load.
- Integrations: Experience with payment processors (Stripe, etc.) and—crucially—an interest in working with hardware integrations (printers, scanners, IoT).
- US Startup Availability: You are comfortable working late hours and staying responsive during critical festival launches.
- Mobile Awareness: Knowledge of mobile development (React Native) is a plus.
- English: Upper-Intermediate or higher. You must be able to explain complex technical trade-offs to the founders.
Responsibilities:
- Engineer the Core: Design and develop the backend and frontend for the Ticketing Platform.
- Solve Hard Problems: Implement logic for Reserved Seating, interactive maps, and complex order flows.
- Hardware & Gate Logic: Write code that interacts with the physical world (scanning tickets, printing).
- Performance: Optimize the app to handle traffic spikes during ticket sales drops.
- Quality & DevOps: Write testable code, manage CI/CD pipelines, and deploy to GCP. You break it, you fix it.
We Offer:
- High Reward for High Performance: Competitive salary + Advanced Bonus System (We reward those who build the business with us).
- Real Engineering Challenge: No CMS wrappers. Pure custom development on an actual stack.
- Direct Impact: Your code runs the show at real festivals in the US.
- Medical Insurance in Ukraine and Multisport program in Poland.
- Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
- Paid vacation, sick leaves, and official holidays.
- Legal & Accounting services.
- The company provides all necessary equipment.
- English classes and Education reimbursement (50%).
