Hi! My name is Vera, I am the founder and CPO of PromoOS. In brief: who we are, where we are now, who I’m looking for, and where we are going.

Who we are

PromoOS is a platform for automating content marketing and promotion: it covers the entire cycle for an entrepreneur, from content strategy to ready-made materials and their publication, as well as advertising, blogger integrations, and much more.

I came to the product from business – I managed companies and consulted them, and I am building PromoOS to my own quality standards. The demand is real: people to whom I show the product react with strong interest and await the launch.

Our current task is to finalize and launch; the plans for functionality are ambitious.

Where we are now

We are in the stage of final touches and preparation for launch. A lot has already been done, but the product lacked a CTO and the expertise to consolidate development into a single system. That is why I am looking for someone who will make the development clear and systematic, something that can be relied upon.

I myself write prompts and set the product’s architecture and logic. I need support on the code side – a person who anticipates and closes risks in advance, rather than putting out fires after the fact or treating the work carelessly.

Technology:

1. Backend: C# / .NET 10, ASP.NET Core Minimal API, EF Core + PostgreSQL, RabbitMQ, Docker. A separate generation service. The core is an AI pipeline (text, image, and video generation through external AI models via API). Plus integrations for posting to social media (separate APIs, not AI), file storage, and service features: dictation, overlaying text on images, cropping images.
2. Frontend: mostly ready. I am currently overseeing it – but I am ready to hand over the technical part to you if you take it on.

Who I’m looking for

A playing technical leader: someone who writes code and designs architecture (60-70%) and leads development (30-40%), evaluates and builds a team, and maintains standards. Someone who takes 100% responsibility for ensuring the code finally works and doesn't require re-checking on our part.

I have high standards for myself and the product. I’m looking for someone similar: a person who enjoys the beauty of their craft, not just closing tasks, to be proud of what we are doing together.

The format is flexible: yourself, with the help of the team, through AI tools (Claude Code) – in any proportion. There are in-house and outsourced developers, but any effective configuration will do – however you assemble it, that’s how it will be, as long as it works.

Our values

• 10/10, no less. We don’t settle for “good enough,” only a level we can be proud of.
• Results. Completed work is valued, not the process for process’s sake.
• Impeccable client experience. The client never stumbles – everything works and is understandable.
• “Nothing is impossible – there is a search for a solution.” Not “this can’t be done,” but “how can it be done?”
• Deadlines and promises. What we promised – we delivered. We keep our word.
• Inspiration. We enjoy the process, the result, and how we work together.

This vacancy is for you if:

1. You have 5+ years of experience in C# / .NET, proficient with EF Core, PostgreSQL, Docker
2. You have experience as a tech lead/architect/CTO in a product team and experience building a team
3. You have real code review, testing, and security (JWT/OAuth, OWASP) experience
4. You have experience with API integrations and pipeline design; working with AI via API is a plus
5. You have worked with Claude Code / AI development assistants – meaning you know how to use tools to increase efficiency, rather than rejecting them by default.

What you will do

1. Assess the current state of the tech department
2. Determine what needs to be improved, with what resources, and in what order
3. Implement engineering hygiene
4. Establish processes that are currently missing: code review, testing, CI/CD, standards
5. Take responsibility for architecture and security – secure the perimeter, organize secrets and access
6. Develop the AI pipeline: integrations with models via API, generation queues, fault tolerance, cost control
7. Build a team under your leadership (in-house + outsourced) together with HR – hire, manage, control quality

The main result of your work

1. The code finally works and doesn’t require our re-checking – this is the main guarantee
2. Processes (review, tests, CI) are established in such a way that quality is maintained automatically, without manual founder control
3. The team is assembled and delivers verified results on time

Working conditions

• Salary: actual net amount – from 300,000 to 500,000 ₽
• Format: full remote (CIS / RF), flexible schedule within working hours (negotiable)
• Employment: contract / individual entrepreneur / self-employed – as convenient for you
• After the probationary period, we will discuss stock options

How to join the team

I am only considering applications with a cover letter that briefly describes your experience as a tech lead/architect/CTO. After applying, I will send a mini-questionnaire, and based on the results, we will schedule a meeting.

See you on the PromoOS team! 🚀
