Delasport — Implementing Technological Solutions Here and Now

Delasport is an iGaming software company providing Sports Betting & Online Casino software and turnkey B2B solutions. Since 2010, we have made a significant impact on the industry, earning awards and expanding our global presence. With offices in Bulgaria, Ukraine, and Malta, our team of more than 500 experts continues to drive innovation and strive for excellence. We are looking for top talent to join our R&D center in Kyiv.

The Product Launch team is built for people who don’t just maintain systems but create them. We take products from zero to hero, and scale them until they’re strong enough to be handed over to core teams. No legacy constraints. No endless support cycles. Just greenfield builds, modern tech, and real ownership from day one.

We move fast, think lean, and execute with focus, one product at a time, full commitment, full impact. Every sprint matter, every decision ship value. This is not a support team. It’s a build-from-scratch engine for products that matter, because every hero needs a superhero.

• Hands-On Engineering - Stay deeply hands-on with production code. Lead by example in modern Java (21/25), Spring Boot 3/4, PHP, Laravel, NodeJS, Kafka Streams, and cloud-native microservices. Conduct in-depth code reviews and contribute to critical path development
• Observability & Operational Excellence - Define and drive observability standards (metrics, logging, tracing, alerting) to ensure production systems are transparent, diagnosable, and reliable
• Technology Adoption - Drive the adoption of new technologies and practices across teams. Build proof-of-concepts, define migration paths, and ensure smooth rollouts with minimal disruption
• Cross-Team Collaboration - Act as the technical mediator between Java teams, Team Leads, the Architect, and business stakeholders. Translate business requirements into sound technical guidance and ensure alignment across all parties
• Knowledge Sharing - Foster a culture of technical excellence through design reviews, tech talks, documentation, and hands-on mentoring of senior engineers

• Test new SEO approaches to increase organic traffic
• Collaborate with the team to identify growth opportunities

• Experience with Google Search Console and Google Analytics
• Familiarity with large websites or aggregators is a plus
• Comfortable learning and adapting to new tools

Growth

This role offers a clear path to take on more responsibility and grow within our SEO team.

Work format

• Office-based
• Warsaw, Poland (or relocation to Warsaw)

✈️ Ready to build and scale? We’re waiting for your application.

Engagement: Contract (full-time) · Remote

Stack: React (primary) · Python (backend) · existing Vue · AWS DynamoDB · in-house UI toolkit

ABOUT THE ROLE

You'll work on the internal compute-platform web application of a US robotics / autonomous company — the system that runs safety simulations and large-scale compute workloads (training, batch inference, MapReduce-style jobs) across a cluster of roughly 50,000–100,000 nodes.

The app is the task-management UI where engineers submit and track jobs: job status and queue time, debugging, and understanding jobs modeled as DAGs (directed acyclic graphs) — which steps ran, which failed, what resources were consumed, why a job is slow, and how to optimize it (e.g. GPU utilization, switching between CPU/GPU nodes).

The application is ~10 years old; its first version was in Vue, and a React migration began ~18 months ago (the team is now building the next major version). The approach is incremental: a host shell with key pages implemented in React, iframing much of the older Vue app. Today it's ~90% frontend — a React app calling many existing services — and will grow its own dedicated Python backend over time, moving toward roughly two-thirds frontend / one-third backend in steady state.

This is a senior, autonomous role. Design/product support is limited to UI polish, so you'll exercise product judgment yourself — walking through user flows as a user, and asking clarifying questions when a ticket isn't well-defined.

WHAT YOU'LL DO

• Build and rework user interfaces in React; migrate the remaining Vue components to React and build new React components.
• Reuse the team's shared component library / in-house UI toolkit.
• Grow a lightweight Python backend — application-level joins, light workflow/processing, a DynamoDB store for things like user preferences — while the app continues to call many existing services.
• Visualize complex job/DAG data clearly: status, failures, resource usage, and performance.
• Talk to users, clarify ambiguous requirements, and ship features end to end.

MUST-HAVE

• Strong, hands-on React — modern hooks, component architecture, state management, performance.
• Solid Python for backend development.
• General database experience.
• A product mindset: questions whether a ticket is well-defined, pushes back constructively, drives clarity instead of waiting for prescriptive specs.
• Ability to operate at a senior level — autonomous, user-facing, proactive, comfortable owning features end to end.

NICE-TO-HAVE

• Ability to read and understand Vue (to migrate existing components).
• Experience with complex data visualization / dashboards, ideally graph/DAG rendering.
• WebGL — only for advanced graph visualization; genuinely optional (fine without it).
• Experience with a shared component library / design system.
• Experience with internal developer platforms, compute, or infrastructure tooling.

WHAT SUCCESS LOOKS LIKE

In the first months you'll take ownership of meaningful parts of the app — migrating Vue screens to React, shipping UI improvements users notice, and starting to shape the Python backend — while reducing the hand-holding needed to move a feature from idea to production.

# About Us

Smirnov Labs is a fast-growing engineering company founded by an ex-Googler. We help product teams launch and scale quickly by leveraging modern technology and AI-assisted development.

Our projects are diverse — we partner with clients at the earliest stages and own the technical delivery end-to-end.

We're a small, senior-heavy team where every engineer has real impact. No bureaucracy, no hand-holding — just sharp people shipping fast.

This is an outstaff role: you'll be embedded directly with a client's engineering team as part of our delivery group.

## What You'll Do

- Own frontend features end-to-end: from architecture and implementation to deployment and support.

- Build and ship web applications in a TypeScript monorepo — Vue 3, Nuxt, Pinia, and Tailwind.

- Build rich, reactive UIs with the Composition API and TanStack Query (Vue Query) for data fetching and state.

- Design reusable component libraries and maintain a scalable, well-typed frontend architecture.

- Integrate with backend APIs and collaborate on API contracts with the client's engineering team.

- Care about performance, accessibility, and UX polish — from bundle size to loading states.

- Work in a codebase that's actively being rewritten — under strong code review and automated review rules — and help raise the bar as you go.

- Communicate directly with the client's engineering team — no layers in between.

- Use AI-assisted development tools (Claude, Cursor, GitHub Copilot) as part of your daily workflow.

- Work across diverse projects — different domains, different challenges.

## What We're Looking For

- 5+ years of professional frontend development experience

- Strong TypeScript skills

- Solid hands-on experience with Vue 3, Nuxt, and the Composition API

- Strong grasp of Vue state management and data fetching (Pinia, TanStack Query / Vue Query, or similar)

- Solid CSS skills and experience with utility-first styling (Tailwind a strong plus)

- Strong eye for performance, accessibility, and responsive design

- Experience integrating with REST/GraphQL APIs

- Comfortable working in a monorepo and in a codebase under active rewrite, with strong code review and automated review gates

- Comfort working in the US timezone (overlapping working hours required)

- Upper-Intermediate or higher English

- Ability to own and drive features independently with minimal supervision

## What We Offer

- Competitive salary above market average

- Fully remote work

- Flat structure — work directly with the client's engineering team, no middle management

- Diverse and technically challenging projects

- Modern AI-powered development workflow

- Small team culture — your voice matters, your code ships

- Paid vacation and sick leave

- Flexible schedule within the US timezone overlap

- Professional and career growth through real ownership, not courses and certificates
