    Who:
    We are looking for a senior full-stack product engineer who builds complete features end-to-end using AI-first workflows, not manual coding.

    What:
    You will own product features from idea to production using Claude Code to generate, iterate, and ship SvelteKit frontend and Golang backend functionality.

    When:
    Start ASAP.

    Where:
    Fully remote, with availability within European or African time zones.

    Why:
    We believe AI should do the coding, while engineers focus on product decisions, architecture, quality, and speed.

    Office Environment:
    Fast-moving, product-driven team with no QA layer, minimal process, and a strong bias toward shipping.

    Salary:
    Competitive, based on experience and demonstrated AI-first engineering capability.

    Position Overview

    This is not a traditional engineering role. We are building products with an AI-first mindset, where Claude Code is the primary tool for writing code. Your job is to guide the AI, review its output, make architectural decisions, and ship reliable features fast.

    What You’ll Actually Do

    • Own features end-to-end: specification, generation, deployment, and bug fixes
    • Use Claude Code to generate SvelteKit frontend and Golang backend code
    • Review AI-generated code for correctness, performance, and architectural fit
    • Fix bugs to learn the codebase, then rapidly build new features
    • Decide what to build, buy, or generate with AI
    • Talk directly to customers when issues arise and ship fixes the same day

    Our Stack

    • Frontend: SvelteKit, Turbo monorepo, Vercel
    • Backend: Golang monorepo
    • AI: Claude Code (mandatory), other agentic coding tools

    Products You’ll Build

    • APIs for platform features, tooling, and multi-agent systems
    • Internal tools and dashboards
    • B2B and B2C web applications

    You Must Have

    • Proven, hands-on experience with Claude Code or similar agentic AI tools (Cursor, Windsurf, etc.)
    • 5+ years of full-stack engineering experience (exceptional 4-year candidates considered)
    • Strong understanding of SvelteKit and Golang (you must be able to review and reason about AI-generated code)
    • Ownership mindset and responsibility for everything you ship
    • Product thinking — you care deeply about why something is built
    • High quality bar — you test your own work thoroughly (no QA team)
    • Excellent spoken English (Upper-Intermediate or Advanced)
    • Reliable internet connection for daily video calls

    You’re a Great Fit If You

    • Get frustrated when development takes weeks instead of days
    • Think in features, systems, and architecture — not lines of code
    • Quickly spot subtle bugs in AI-generated output
    • Ship fast, but always verify things actually work
    • Have shipped real products used by real customers

    Engineering Team Lead — Python to $7000

    Full Remote · Countries of Europe or Ukraine · 8 years of experience · English - B2
    From Team Lead to Product Leader: are you ready for the next level? Many engineering leaders reach a point where “another project” stops being exciting. Deadlines change, scopes shrink, teams rotate — and eventually you deliver a finished feature… but...

    From Team Lead to Product Leader: are you ready for the next level?
    Many engineering leaders reach a point where “another project” stops being exciting.
     Deadlines change, scopes shrink, teams rotate — and eventually you deliver a finished feature… but not real impact.
    A true product is different.
     It lives. It grows. It has real users, real scale, and a long-term future.


    Right now we’re looking for a Python Team Lead to take ownership of a product like this — a mature, successful SaaS platform used daily by thousands of organizations in the US.


    What makes this role truly interesting for a Lead:

    🔹 Full ownership, not task execution
     You lead a cross-functional squad of 5–7 engineers (backend, frontend, QA) and own the entire lifecycle: architecture → development → release → production stability.
    🔹 Real influence
     This is not “just managing tickets.” You’ll shape technical direction, work directly with architects and product managers, and impact how the platform evolves.
    🔹Serious engineering scale
     Modern stack: Python (Django + FastAPI), microservices, cloud infrastructure, fully automated CI/CD, high-availability distributed systems. A product where things must work 24/7.
     🔹Hands-on technical leadership
     You remain a strong technical expert while mentoring engineers, improving processes, and building a high-performing team.
    🔹Remote-first culture
     Fully remote environment built on trust, autonomy, and strong engineering collaboration.


    This role fits leaders who:
    🔹 BSc in Computer Science or equivalent;
    🔹 8+ years of software engineering experience, including 5+ years of Python in production;
    🔹 3+ years in an R&D team lead, leading cross-functional teams (backend, frontend, and QA) in a production environment;
    🔹 Proven experience managing and leading remote teams in a fully distributed, remote-only environment;
    🔹 Proven experience working in a product-based company (not project/outsource);
    🔹 Strong experience with Python backend development in a SaaS environment, including cloud-based, scalable, and high-availability distributed systems;
    🔹 Strong knowledge of REST APIs, microservices, asynchronous programming, and testing;
    🔹 Hands-on experience with CI/CD pipelines and Infrastructure-as-Code (e.g., Terraform, Helm);
    🔹 Solid understanding of software architecture, design patterns, and technical trade-offs;
    🔹 Proven experience delivering long-term SaaS and customer-facing products with full end-to-end responsibility — from design to production and ongoing support.
    🔹 Excellent communication skills and high proficiency in English.

    Why Join Us?

    At YozmaTech, we’re self-starters who grow together. Every day, we tackle real challenges for real products — and have fun doing it. We work globally, think entrepreneurially, and support each other like family. We invest in your growth and care about your voice. With us, you’ll always know what you’re working on and why it matters.

    From day one, you’ll get:

    🔹 Direct access to clients and meaningful products;
    🔹 Flexibility to work remotely or from our offices;
    🔹 A-team colleagues and a zero-bureaucracy culture;
    🔹 Opportunities to grow, lead, and make your mark.

    After you apply

    We’ll keep it respectful, clear, and personal from start to offer. You’ll always know what project you’re joining — and how you can grow with us.

    Everyone’s welcome

    Diversity makes us better. We create a space where you can thrive as you are.

    Ready to build something meaningful?

    Let’s talk. Your next big adventure might just start here.
