Careers at Mejix
Build software that ships. Work with engineers who care. Join a team obsessed with delivery.
We're a certified Shopify Plus agency and software consultancy — US-managed, with engineering teams in New York and Cluj-Napoca, Romania. We build AI products, Shopify Plus stores, and custom software for clients across 12 countries. If you're a senior engineer, designer, or product person who wants to work on real products that ship, we'd like to talk.
A delivery-first agency that uses AI to build faster
We're not a startup. We're not an enterprise. We're a senior team of 29 engineers, designers, and PMs who have been building software together for over 10 years — with the focus, culture, and processes to keep delivering.
A senior, focused team — not a volume house. Every engineer here works on real products with real accountability.
Our clients and team members span North America, Europe, and beyond. We build for global products with global standards.
A decade of shipped software. We know how to scope a project, run a sprint, and get things live — reliably.
What it's actually like to work here
We don't have a ping-pong table. We have engineers who ship things on time, a culture of ownership, and clients who come back because the last project was delivered properly.
Delivery is the culture
Our tagline is 'Obsessed with Delivery' — and it's not marketing copy. We run structured sprints, commit to milestones, and treat shipping on time as a professional standard. If that sounds like where you want to work, you'll fit in.
AI is part of how we work
We use AI throughout our development process — planning, code generation, documentation, QA. We've shipped AI products in production (Yehuda's diamond detection, NES, LoveLock). You'll work alongside AI, not be threatened by it.
Remote-first, US-managed
Our engineering teams are based in Cluj-Napoca, Romania, with US-based project management. You'll work with senior people who communicate well, respect your time, and give you the context you need to do your job properly.
What you get at Mejix
Competitive salary
Benchmarked against senior engineering roles in Romania and the US market. We pay fairly and review salaries annually.
Annual learning budget
Dedicated budget for courses, certifications, conferences, and tools. Shopify Developer certification, AWS, OpenAI — your growth is an investment.
Remote-first flexibility
Work from Cluj-Napoca, home, or a coworking space. We measure output, not presence. Results matter more than where you sit.
Modern tools and stack
React, TypeScript, Tailwind, Supabase, Vercel, Shopify Plus. No legacy codebases. No framework archaeology. New projects on clean stacks.
Senior team only
You won't be the most experienced person in the room and be expected to mentor three juniors simultaneously. We hire senior and expect senior.
International clients
Work on products used in the US, Europe, and beyond. Real scale, real complexity, real client standards — not local projects with low expectations.
AI tooling throughout
We use AI at every stage of the development process. You'll be equipped with the tools that make senior engineers more effective — not threatened by them.
Growth and ownership
We're a focused team that moves fast. If you do excellent work, you'll take on more responsibility. There's no 3-year wait to do the interesting work.
We hire engineers who take ownership
Regardless of the specific role, every person at Mejix shares a few core qualities. These aren't aspirational values on a wall — they're how we actually work.
You default to delivery
You define success as shipping, not starting. You've been in codebases where things slipped and you found that unacceptable. You push for clarity on scope, commit to milestones, and flag blockers early rather than absorbing them silently.
You think before you build
You ask why before you start. You've saved clients from building the wrong thing by asking the right questions at the specification stage. You understand that a week spent clarifying requirements prevents a month of rework.
You own your output
When something you built has a bug in production, you fix it — you don't wait to be asked. You test your own work before handing it off. You document what you build because you'd want the next person to be able to pick it up.

Hear from the people who work here
"I joined Mejix because I wanted to work on real products with real deadlines — not internal tools with no users. Two years in, I'm working on Shopify Plus stores for US brands and AI products that are live in production. The bar is high and I like that."
"What surprised me most is how much ownership I have. I'm not implementing tickets — I'm involved in architecture decisions, client conversations, and product strategy from the start of an engagement."
"The US-managed model is real. I talk directly to the project manager in New York about delivery, and I talk directly to the client about the product. It's not a layer-by-layer communication chain. Things get decided and move."
