Senior .Net Developer (AI Product) en España is listed on Jobeax. Browse 80,000+ vacancies available.

About the role

Your main tasks will be:

What you'll do

Contribute to the architecture of high-load services and grow the existing C# / .NET Core codebase.
Build new product features and integrations, including the AI layer (voice, real-time, and — on the horizon — video and emotion recognition).
Design and operate async pipelines on RabbitMQ: delivery guarantees, idempotency, error handling, backpressure.
Work with MS SQL schema and queries under load: indexes, execution plans, hot-path optimization.
Hold the bar on code quality across the team: code review, testing, observability, engineering standards; influence technical decisions beyond your immediate area.

What we're looking for

We expect from you:

5+ years of commercial C# / .NET development, including 2+ years on .NET Core in production.
Real distributed-systems and high-load experience: you can reason about throughput, latency, and fault tolerance through specific incidents from your own past, not from a textbook.
Hands-on experience with message brokers (RabbitMQ preferred; Kafka / Azure Service Bus / NATS acceptable with a high-load track record) and MS SQL Server under load.
Fluent Russian, ready to work in CET (±2) hours.

What you'll get

What do we offer:

REMOTE OPPORTUNITY to work full-time;
Vacation 28 calendar days per year;
7 wellness days per year (time off) that can be used to deal with household issues, to lie down and recover without taking sick leave;
Bonuses up to $5000 for recommending successful applicants for positions in the company;
50% payment for professional training, international conferences, and meetings;
Corporate discount for English lessons;
Health benefits. According to the paychecks, if you are not eligible for corporate medical insurance, the company will compensate you with up to $ 1,000 gross per year per employee. This can be spent on self-purchase of health insurance or on doctor’s fees for yourself and close relatives (spouse, children);
Workplace organization. The company provides all employees with an equipped workplace and all the necessary equipment (table, armchair, wifi, etc.) in our offices or co-working locations. In the other locations, the company provides reimbursement of workplace costs up to $ 1000 gross once every 3 years, according to the paychecks. This money can be spent on the rent of the co-working room, on equipping the working place at home (desk, chair, Internet, etc.) during those 3 years;
Internal gamified gratitude system: receive bonuses from colleagues and exchange them for our merchandise, team building activities, massage certificates, etc.

Sounds good? Join us now!

The initial pay level or pay range for this role will be shared with candidates during the recruitment process and before the commencement of employment.
