About the Job

Requirements

Strong experience in product-driven companies, with the ability to measure feature success and focus on retention, conversion, and user experience.
Practical experience integrating large language models or artificial intelligence tools into production applications, or an advanced workflow using AI assistants to improve development speed.
A proven track record of shipping features focused on business key performance indicators rather than only writing code.
Strong knowledge of TypeScript and JavaScript, with a deep understanding of Node.js.
Commercial backend development experience with NestJS.
Strong frontend experience with modern frameworks such as React or Next.js.
Experience with relational databases such as PostgreSQL or MySQL, including query optimization.
Experience working with MongoDB at scale, including 100 million or more documents or 50 GB or more of data.
Experience with RabbitMQ.
Deep understanding of the HTTP/1.1 protocol.
Proven experience refactoring legacy codebases or major architectural components.
Solid experience with version control systems such as Git.
Fluency in English and Russian.

Responsibilities

Own products end to end by taking a problem from product or a founder, writing the specification, deciding scope, building and shipping the solution, monitoring the metric, and iterating when the metric does not improve.
Work directly with product, challenge proposals where appropriate, and jointly decide what is worth building each week.
Set rules for AI agents used for code review, test generation, and boilerplate; review their outputs and maintain a high quality bar for agent-produced code.
Own production health for the area, including bug counts, incidents, test coverage, and the long-term shape of the codebase being modified by agents.
Track lead time, throughput, and agent cycle time, establish a personal baseline in week two, and work toward an improvement target by month two.
Push back on work that should not be built, using short experiments or metric-based reasoning to assess whether it is worthwhile.

Desired Qualifications

Experience designing complex information system architectures from scratch.
Experience with Redis for caching or publish-subscribe messaging.
Experience working in Agile or Scrum environments.

Responsibilities

What you'll own

Products end-to-end. You pick up a problem from product or a founder, write the spec yourself, decide what's in and out of scope, build it, ship it, and watch the metric. If the metric doesn't move, you figure out why and try again.
A direct line to product. No PM in the middle. You talk to product directly, push back when you should, and decide together what's worth building this week.
A team of agents. Claude (or whatever ships next month) handles code review, test generation, and boilerplate. You set the rules, review the reviews, and keep the bar for agent-produced code in your project above the company average.
Production health in your area. Bug count, incidents, test coverage, the long-term shape of the codebase agents are touching. You own the number, and we measure it.
Speed, measured. Lead time, throughput, agent cycle time. You'll have a personal baseline in week 2 and an improvement target by month 2. We don't count tickets closed.
Saying no. Roughly a third of what lands on your plate shouldn't get built. The right answer is often "let's run a 2-day experiment first" or "this doesn't move a metric we care about". Push back with reasoning, not instinct.
