We are building a fully automated self-service registration system for MongoDB databases, implemented entirely in n8n. The system allows internal users to request new MongoDB databases or access to existing ones, handles an owner-based approval flow, and manages secure one-time password delivery — all without manual admin intervention.

The project is well-specified: a detailed technical concept and a phased workplan are ready. Your job is to implement it.

What You Will Build

The system consists of 7 n8n workflows:

- WF-01 – Registration form with routing logic

- WF-02a – Reusable sub-workflow: user creation via MongoDB Ops Manager API

- WF-02b – Database initialization (3 collections + vector search index)

- WF-03 – Access request flow for existing databases

- WF-04 – Owner approval form (approve / reject with permission levels)

- WF-05 – One-time password reveal form (secure, token-based)

- WF-06 – Scheduled cleanup (expired tokens, user deletion, notifications)

Supporting infrastructure: 3 n8n Data Tables, Microsoft Outlook integration, and MongoDB Ops Manager REST API integration.

The project is structured in 4 phases, each ending with a testable milestone. Phase 0 consists of PoCs to validate all external connections before any workflow is built.

## Your Responsibilities

- Implement all workflows according to the provided concept and workplan

- Conduct PoCs for MongoDB Ops Manager API, MongoDB direct connection (admin credential, dynamic database naming), vector search index creation, and Outlook integration

- Build and test token-based forms (password reveal, approval)

- Set up n8n Data Tables and credential management

- Perform end-to-end tests for both registration scenarios (new DB and access request)

- Handover with documentation of any deviations from the concept

Required Skills

- n8n – solid hands-on experience building multi-step workflows, including Webhook Triggers, Form Triggers, Execute Workflow, Code Nodes, and HTTP Request Nodes

- REST API integration – comfortable reading API docs and translating them into HTTP Request Nodes

- MongoDB – understanding of databases, collections, users, and roles; experience with the MongoDB driver or direct connections

- JavaScript – for Code Nodes (password generation, token logic, dynamic expressions)

- Microsoft Graph API / Outlook – experience sending emails from n8n or similar tools via OAuth2

Nice to Have

- Experience with MongoDB Ops Manager or MongoDB Atlas Admin API

- Familiarity with MongoDB Vector Search and index configuration

- Experience with n8n Data Tables and n8n's self-hosted setup

- Experience building secure, token-based one-time-use forms in n8n

Project Details

 Phases 0–4 as defined in the workplan 

 All 7 workflows implemented and tested in n8n, handover documentation |

Collaboration Close coordination with the project lead during PoC phase; largely autonomous implementation afterwards |

Environment n8n instance provided; MongoDB Ops Manager and Outlook credentials will be made available

How to Apply

Please send a short introduction and relevant project references, include examples of n8n workflows you have built, particularly any involving REST API integrations, dynamic data handling, or form-based user flows.

PRAI builds Advanced PR AI Agents that automate operations, track global narratives, pitch 100K+ journalists, and decode media impact for organizations worldwide. We don't talk about AI transformation — we ship it. Our platform is live, our roadmap moves fast, and we're looking for A-players ready to build the infrastructure that powers next-generation AI Employees.

The Role

We need a Senior Full Stack Engineer who can take full ownership of product areas — from architecture to production — and use AI tooling daily to move faster than a traditional engineering team.

This is not a ticket-execution role. You'll work directly with founders and product leadership, influence technical decisions, and see your work running in production within weeks of joining.

The Team

You'll be working alongside people with backgrounds at:

• PwC
• McKinsey & Company
• EY
• SoftServe
• Apple
• Uber
• Baykar

We operate at startup pace — decisions get made fast, priorities shift when they need to, and everyone keeps up. Expect a mix of async work and live Zoom calls within the same day, screen sharing, real-time problem solving. We're transparent about using a time tracker — if you're confident in your output, it won't be an issue.

What You'll Do

• Build and ship AI-powered full-stack products from architecture to production — owning features end-to-end
• Integrate LLMs, AI agents, and automation systems using OpenAI, Anthropic, and custom prompt workflows
• Develop modern frontend interfaces in React and/or Angular, backed by scalable Python and Node.js services
• Design and maintain APIs, internal tooling, and data pipelines supporting real operational workflows

• Identify engineering bottlenecks and fix them proactively — without being asked
• Collaborate directly with founders and product leadership to turn concepts into working systems
• Maintain high engineering standards in a fast-moving environment

What We're Looking For

Must-haves:

• 5+ years of full-stack engineering experience — shipped real products, not just contributed to them
• Strong command of Python and JavaScript/TypeScript across frontend and backend
• Hands-on experience with React and/or Angular in production
• Direct experience integrating LLMs or AI APIs (OpenAI, Anthropic, or equivalent)
• AWS or GCP at production scale — Docker, CI/CD, infrastructure ownership
• Fluent in Ukrainian or Russian — our core team communicates in these languages daily
• English C1 — clear communication with international stakeholders
• Operates without micromanagement — you drive your own execution

Strong advantage:

• Startup or scale-up background where you owned outcomes, not tasks
• SaaS or AI-native product experience end-to-end
• DevOps or infrastructure ownership beyond basic deployment
• Product intuition — you think about user impact, not just code
• Systems thinking — you design for scale from the start

Core Technologies

Frontend: React, Angular, Next.js, TypeScript, JavaScript, Tailwind CSS Backend: Python, Node.js, REST APIs, GraphQL AI / Automation: OpenAI API, Anthropic API, AI agents, prompt systems, Cursor, workflow automation Infrastructure: PostgreSQL, Redis, Docker, AWS / GCP, CI/CD pipelines

What We Offer

• Fully remote — work from anywhere
• Full-time, EST-aligned schedule (7:00 AM – 4:00 PM EST)
• Direct access to founders — short feedback loops, real influence
• High ownership and product impact from day one
• AI-first development environment — cutting-edge tooling daily
• Minimal bureaucracy — decisions happen fast
• Competitive compensation based on experience and capability

How We Work

EST hours — 7am to 4pm. Direct communication, no layers between you and decision-makers. We move fast, speak plainly, and value people who take full accountability for their output.

How to Apply

Send your CV and a short note on the most complex AI or full-stack product you've built — what it did, what you owned, what you'd do differently. No templates. No generic applications.

Our process: HR screen (15 min) → technical interview (1 hour) → hiring manager interview (up to 1 hour). We respond within 3–5 business days.

While other teams are still discussing AI transformation — we're building it.

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.
