Ready to build something meaningful?

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

Our design and digital studio is looking for a senior developer in Kyiv to join our studio and help build refined, bespoke websites for brand, commerce, and digital product clients.
 

This is not a generic WordPress or template implementation role. We are looking for someone who has real experience building custom, design-forward websites from scratch, especially for design studios, creative agencies, premium brands, or high-end digital products.

You should be comfortable owning both front-end and back-end development, working closely with designers, translating detailed design systems into polished production websites, and making smart technical decisions without needing heavy supervision.

What you’ll work on

You’ll help build custom websites and digital systems for clients across brand, e-commerce, editorial, and product experiences.
 

Projects may include:

• Bespoke marketing websites
• Headless CMS builds
• Headless e-commerce experiences
• Shopify and Shopify Plus builds
• Custom front-end systems
• API integrations
• Experimental or interaction-heavy websites

• Design-forward digital experiences that need to feel highly polished

   

You’ll work directly with designers and strategists, so strong taste, attention to detail, and clear communication are essential.
 

Requirements

You must have:

• 5+ years of experience
• C1 English or higher
• Based in Kyiv
• Able to work from our office in Kyiv city center at least 4 days per week
• Strong front-end and back-end development ability
• Real experience building custom websites from scratch
• Experience working with design agencies, creative studios, or design-forward teams
• Strong understanding of responsive design, performance, accessibility, and production-quality implementation
• Ability to work independently and make senior-level technical decisions
   

Technical experience we’re looking for

You should have strong experience with:

• Modern front-end development
• Back-end development
• Headless CMS architecture
• Sanity
• Headless e-commerce
• Shopify and Shopify Plus
• REST API integrations
• GraphQL API integrations
• Custom CMS and commerce workflows
• Bespoke website builds, not just templates or theme modifications

• Experimental development, motion, interaction, and polished front-end details

   

You do not need to know every tool perfectly, but you do need to be senior enough to figure things out quickly, make good architectural decisions, and ship excellent work.

What makes someone a strong fit

You are probably a strong fit if:

• You care deeply about craft, not just functionality
• You notice when spacing, motion, typography, or responsiveness feels off
• You can collaborate with designers without needing every edge case over-explained
• You understand that premium websites require both engineering judgment and visual sensitivity
• You can own a build from technical setup to launch
• You can communicate clearly when something is risky, unclear, overcomplicated, or needs a better approach

• You have built real websites for real clients, brands, studios, or commerce businesses

   

What this role is not

This is not a role for someone who has only worked with basic themes, simple landing pages, or low-code tools.

This is also not a junior or mid-level role. We need someone who can operate as a senior developer and take responsibility for the quality of the final product.
 

Compensation

$2,500-$3000 USD per month

This is a full-time role based in Kyiv with a minimum of 4 days per week in person from our office in the city center.

This role is part of the Keyword.com team — one of the growing brands within saas.group.

Keyword.com is a keyword rank tracking and SERP & AI Visibility analytics platform that helps SEO teams track rankings and uncover opportunities that matter.

As we continue to grow, we're seeking a Senior Product Engineer to own and deliver end-to-end features that move the product forward. You won't just write code — you'll identify user problems, prototype solutions, ship features, and iterate based on real usage data. If you're someone who thinks in terms of user outcomes rather than tickets, thrives on autonomy, and is excited about shipping software that customers actually use, this role is for you.

Profile Overview

Your immediate impact in the first 1-3 months will be:

• Become a core member of our product engineering team, owning features from idea to production
• Ship user-facing features end-to-end, including frontend UI, backend services, and data pipelines
• Improve existing product areas based on customer feedback and usage data — reducing friction, fixing rough edges, and raising the bar on quality
• Help shape our product roadmap by bringing opinions backed by data, prototypes, and customer conversations
• Analyze usage data and use those insights to shape what you build next
   

Your responsibilities
 

• Own product outcomes end-to-end: from identifying user problems and prototyping solutions to shipping, measuring, and iterating
• Build and maintain the frontend experiences that our customers use every day
• Develop scalable backend services and data pipelines that power those experiences
• Analyze usage data and user feedback to prioritize what to build, fix, and improve
• Collaborate closely with the team on product direction — bring opinions, back them with data, and help set priorities
• Write clear documentation for the features you ship, both readable by humans and LLMs

What You bring to the table

• 5+ years of full-stack development experience, with a strong track record of shipping user-facing products end-to-end
• Proficiency in Node.js (TypeScript) for backend services; knowledge of other backend languages is a plus
• Solid experience with a modern frontend framework — Vue.js or React.js. You're comfortable owning the UI layer of the features you ship, not just handing off APIs
• Experience designing and building data pipelines and working with large-scale data processing
• A product mindset: you think about user problems first, not just technical implementation. You form opinions on what to build and why
• Comfort with ambiguity — you can take a vague problem, break it down, prototype fast, and iterate based on feedback
• Strong communication skills — you can explain technical decisions in terms of user and business impact
• Senior-level ownership: you plan meticulously, ship reliably, and proactively identify risks and opportunities
• Hands-on experience building with LLMs — context engineering, API integrations, agentic workflows

Nice-to-have

• Familiarity with OLAP databases like ClickHouse for analytical workloads
• Background in SEO tools, rank tracking, or search ecosystems
• Experience with web scraping or browser automation
• History of side projects, open-source contributions, or founding your own product

Our Tech Stack
 

• Node.js (TypeScript), PHP (Laravel), React.js
• MariaDB, ClickHouse, PostgreSQL
• RabbitMQ, Redis, Debezium, Kafka

What's in it for You
 

• Ultimate flexibility: We're 100% remote. You can work from wherever you like, whenever you like.
• Freedom and autonomy: We're a high-trust team, and you'll be given lots of flexibility to solve problems in your own way — with plenty of help from the team when you need it.
• Minimum bureaucracy: We don't like to get bogged down with meetings and red tape. We like to be efficient and keep momentum steady & sustainable.
• Small & friendly team: We help each other out, have fun, and joke around.
• Our network: We are a community of entrepreneurial SaaS professionals that regularly exchange ideas, knowledge, learning and expertise with each other internally.
• Flexible time off: We want you to recharge your batteries when needed.
