About the role

You will be a Core Developer in our product team, taking charge of developing and scaling our mobile product. This is a high-impact position where you’ll be involved in the entire product lifecycle: from building core product features and modern UIs to designing a reliable, fast, and efficient infrastructure around it. You’ll work directly day-to-day with the General Manager and have a clear, measurable impact on the product’s unit economics.

Technical stack: AI-driven Engineering, Flutter, Node, TS, React.

What you need for this position

• You’re an AI-augmented engineer. You actively use tools like Copilot, Cursor, or Claude to speed up your routine, refactor efficiently, and solve problems faster.
• At least 5 years of hands-on experience as a Software Engineer (designing & developing both mobile (primarily) and web applications).
• You communicate openly and feel comfortable in a fast-paced agile team where things can change rapidly.
• You’re a truly product-oriented engineer. You don’t just write code in a vacuum — your technical decisions are always driven by real product and engineering metrics, keeping business goals in mind.
• You can solve product and business problems end-to-end completely solo. You know how to take a high-level problem description and turn it into an efficient, working engineering solution without needing someone to hold your hand.
• Familiarity with Google Cloud Platform, particularly Firebase services including Firestore, Storage, and Performance, as well as experience with Firebase Flutter SDK, Bloc, and Hive storage.
• Hands-on experience building backend (Node.js and Lambda preferred). We value any strong backend background; if you haven’t used our specific stack, we expect you to bridge the gap using AI tools and a high “speed of learning” to ship production-ready code.

What You’ll Be Doing

• Design, build, and maintain mobile app and its infra using Flutter and a Node.js backend. Develop and optimize web-frontend (marketing funnels).
• Leverage AI tools (Cursor, Copilot, etc.) to accelerate development, refactor code, and maintain high code quality.
• Take an active role in product management: monitoring how users interact with your features and identifying areas for improvement. You will analyze user flow through marketing funnels, identifying drop-off points and technical bottlenecks that affect conversion. You won’t just wait for tasks; you’ll proactively suggest tech improvements based on data insights.
• Design and implement A/B tests to validate hypotheses, working closely with the product team to optimize core metrics.
• Build a robust, scalable infrastructure.
• Work directly with the General Manager and marketing team to align engineering efforts with business growth and scalability.

Hiring Process

Stage 1: Interview with HR (1h).

Stage 2: Interview with VP of Engineering.

Stage 3: Technical interview.

Stage 4: Interview with the team.

What we offer for your success

• Very warm and friendly working environment and flexible working schedule.
• 20 days off + paid national holidays, and 12 sick days paid by the company per year.
• Medical insurance, and health protection programs (with COVID-19 and dental coverage).
• Continuous professional development and growth opportunities.

A technology company focused on helping businesses move faster with AI by designing and delivering practical, production-grade systems across workflows, operations, and knowledge-heavy use cases. The team works closely with clients to turn AI from experimentation into reliable, scalable execution.

You will work on the pipelines, indexing systems, evaluation frameworks, and production infrastructure that power AI assistants using hosted LLM APIs and internal knowledge sources. This is a hands-on role for someone who can think across ingestion, search, observability, and system performance.

Key Requirements:
🔹 Strong programming skills, especially in Python;
🔹 Experience building ETL and data pipelines in production environments;
🔹 Strong SQL skills and experience with relational databases, preferably, PostgreSQL;
🔹 Experience with search and retrieval systems, including OpenSearch, Elasticsearch, or similar platforms;
🔹 Familiarity with vector databases, embeddings workflows, and large-scale, document indexing;
🔹 Experience with cloud platforms such as AWS and related infrastructure services;
🔹 Familiarity with Git, CI/CD pipelines, and modern engineering workflows;
🔹 Strong problem-solving skills and comfort working across data, infrastructure, and AI application layers;
🔹 English – Upper-Intermediate or higher.

Will be plus:
🔹 Experience working on RAG systems, internal knowledge assistants, or search-heavy AI applications;
🔹 Familiarity with observability stacks, distributed systems, and workflow, orchestration tools;
🔹 Experience with access control, permission-aware systems, and auditability in enterprise environments;
🔹 Exposure to evaluation frameworks for LLM systems and model benchmarking;

What you will do:
🔹Working with Vector Databases
🔹Maintain and improve ingestion and enrichment pipelines for internal and client content, including parsing, extraction, normalization, metadata enrichment, deduplication, and quality monitoring
🔹Improve indexing and retrieval quality through chunking and segmentation refinements, embedding and index update workflows, metadata filtering, and caching
🔹Support hybrid retrieval architectures combining vector search, keyword or BM25 search, and metadata-aware filtering
🔹Implement and maintain access-aware retrieval by propagating and enforcing document permissions at indexing and query time, including audit logs and validation tests
🔹Improve source attribution so responses consistently point to the correct documents, sections, and references in a reliable format
🔹Extend and harden tool execution, workflow orchestration, and automations, including retries, timeouts, idempotency, concurrency controls, and run history
🔹Develop and maintain evaluation and regression testing frameworks, including golden datasets, automated scoring, and structured comparisons across LLM providers and models
🔹Operate AI systems in production, including logs, metrics, tracing, alerting, incident response, performance tuning, cost monitoring, and runbook documentation
🔹Build scalable infrastructure to process, embed, index, and search very large document collections efficiently

Interview stages:
🔹 HR interview;
🔹 30-min screening call;
🔹 Technical interview;
🔹 Test assignment/homework;
🔹 Reference check;
🔹 Offer;
