Jobs

For Ukrainian citizens only

At Scalivo, we deliver Operations-as-a-Service for fast-growing e-commerce brands and global tech companies. We step in where automation and internal capacity fall short - handling day-to-day operations and building strong dedicated teams so business leaders can focus on scaling without complex hiring overhead. We are managing this recruitment process directly on behalf of our client.

About Our Client

Our client is an innovative PropTech platform simplifying co-ownership and fractionated real estate investments. Their product manages the full lifecycle - from buying and selling property shares to guest stay management, booking engines, automated payments, and property operations.

About the Role

We are looking for a Senior Software Engineer / Tech Lead who balances hands-on IC execution with technical leadership. In this role, you will guide architectural decisions, mentor engineers, and ensure high-quality delivery across a full-stack TypeScript ecosystem in close collaboration with product and design teams.

Key Responsibilities

• Technical Leadership: Architect and evolve systems across a TypeScript-based stack (Node.js, NestJS, React, React Native, Next.js); drive distributed and event-driven architecture standards; perform code reviews and mentor engineers.

• Execution & Delivery: Build core features, review PRs, break down complex requirements into actionable work, and maintain strong engineering practices (CI/CD, testing, observability).

   

Requirements

Must-have:

• 6–10+ years of software engineering and technical leadership experience.
• Deep expertise in TypeScript, Node.js, NestJS, along with React, React Native, or Next.js.
• Strong background in cloud environments (preferably GCP).
• Experience designing and maintaining distributed systems and event-driven architectures (microservices, CQRS, Pub/Sub, message brokers).

• Proven track record of leading technical initiatives, mentoring developers, and cross-functional collaboration.

   

Nice-to-have:

• Familiarity with payment security, user data protection, and access control.
• Basic understanding of AI engineering (LLM system integration, prompt design).
• Experience with booking engines, financial/transactional systems, or Domain-Driven Design (DDD).

• Knowledge of DevOps / Infrastructure-as-Code (Terraform, Pulumi).

   

Way of Working

We value true ownership, clear technical communication, team mentorship, and the ability to balance speed of execution with long-term architectural maintainability.

What We Offer

• Rate: €4000 / month.
• Full-time employment and 100% remote work.
• Five-day workweek, full-time (8 hours per day).
• Actively shape a leading European PropTech/Hospitality startup.
• Work directly with experienced founders, dynamic colleagues, and top-class tech/real estate investors.
• Ample room for creativity, experimentation, and modern AI tooling.

As our Senior AI Engineer, you'll own the intelligence layer of the platform — the gateway, tools, retrieval, and evaluation that let an AI assistant read and act inside a regulated ERP as the signed-in user, and never as anything more. In manufacturing that answers to auditors, an assistant that's confidently wrong, or that touches a record it shouldn't, is worse than no assistant at all. Your work is making AI trustworthy enough to put in front of a quality manager.

This isn't a role for working through a queue of well-specified tickets.

 You'll take large features from a loose problem statement to production — agentic workflows, AI on mobile for the shop floor, and the system and infrastructure changes underneath them. You'll decide what to build as much as how, and you'll push for the breakthrough features that make customers switch, not only the ones already on the roadmap.

The ideal candidate thrives in startup ambiguity, moves with real urgency, and has a track record of turning open-ended problems into shipped products without waiting to be told what's next.

What You'll Do

01 — Take large features from idea to production.

Own agentic workflows and AI on mobile end to end. Start from the user's problem, shape the solution, write the plan and the tickets, build the React and mobile interfaces that make AI output trustworthy and actionable, ship it, and measure whether it worked.

02 — Make and own large system changes.

Propose, defend, and carry through the architecture and infrastructure the AI layer depends on — background agents and job queues, observability, cost metering, per-tenant limits, and model version pinning.

Required Qualifications

- 8+ years building and shipping production software, including 2+ years shipping LLM-powered features to real users, and a track record of owning large features end to end.

- AI-native engineering practice — you've rebuilt how you work around agents rather than adding them to an old workflow. Claude Cowork as your primary tool, with strong hands-on experience using Claude Code, Cursor, Codex, or similar; you direct agents through most of the implementation and stay disciplined about the quality, stability, and extensibility of what they produce.

- Product sense and ownership — you work from problems, not specs. You figure out what users and the business actually need, write your own tickets, make the call when the answer isn't obvious, and drive work to done without needing direction repeated.

- Production LLM application engineering — tool calling, structured output, prompt and context design, and streaming, with Claude, OpenAI, or similar, via AWS Bedrock or direct APIs.

- Retrieval-augmented generation in production — chunking, embeddings, and hybrid search on pgvector or equivalent, with access control enforced at retrieval time.

- Evaluation and AI security discipline — you've built eval suites that gate releases, and you design against prompt injection, data leakage through tool output, and cross-tenant access from the start.

- Strong TypeScript, React, and Next.js in production — enough to own the AI experience end to end rather than hand it off.

- Production experience with PostgreSQL — schema design, query optimization, and operating it at scale.

- Hands-on with AWS services — Bedrock, RDS, Fargate, S3, VPCs, IoT Core, DynamoDB, and related infrastructure.

- Disciplined engineering fundamentals — SOLID, DRY, and Domain-Driven Design applied to complex business domains, with unit and integration tests as part of your normal workflow.

- B.S. in Computer Science, Mathematics, Physics, Engineering, or equivalent practical experience.

Preferred Qualifications

- Early-stage startup experience — you've shipped at weekly cadence, owned outcomes rather than tasks, and built something new that changed what the product could do.

- Shipped mobile applications — React Native or similar — for field, operator, or shop-floor use.

- Experience building manufacturing software or Industrial IoT systems — ERP, MES, or SCADA platforms, or machine connectivity over MQTT, OPC-UA, or similar.

- Hands-on with the Model Context Protocol — MCP servers or clients, and OAuth 2.1 authorization for agents.

- C# / .NET experience, as our core services move to a C# and AWS architecture.

- Exposure to compliance frameworks such as SOC 2, GAMP 5, ISO 13485, 21 CFR Part 11, or similar.

• Independently design, develop, maintain, test, deploy, and optimize ingestion, validation, transformation, aggregation, data-quality, anomaly-detection, and extraction workflows
• Develop and tune Python/PySpark packages, SQL extraction queries, Databricks jobs, ADF pipelines, Delta tables, and source-to-target contracts
• Own technical readiness for new cells and refreshes: clarify filters and expected scope, implement or update queries, review mappings/configuration, reconcile outputs, and confirm readiness for business validation
• Investigate source, NCID, taxonomy, hierarchy, mapping, naming-convention, aggregation, missing-week, outlier, and performance issues across CDF, MDFA/PFME, APIs, manual files, and specific sources
• Coordinate technical validation cycles with Product, CMIA/markets, WPP/MDFA, CDF, other data providers, and Ekimetrics; convert reported discrepancies into actionable owners and technical evidence
• Drive complex incident resolution across pipelines, data contracts, access, service principals, secrets, networking, Power BI refreshes, and downstream delivery
• Review pull requests and test evidence; guide the Junior engineer and delegate scoped engineering/support work without becoming a people manager
• Maintain architecture documentation, interface contracts, repository documentation, runbooks, deployment procedures, and support/escalation guidance

• Recommend practical automation, reliability, performance, and maintainability improvements while respecting platform standards and business-validation ownership.

   

Must-have technical competencies:

• 5–6 years’ professional engineering experience with independent production ownership
• Strong Python, PySpark, and SQL, including complex transformations, query optimization, reusable packages, debugging, tests, and reconciliation
• Strong ETL/ELT and batch-pipeline engineering across relational warehouses, APIs, object storage, and file-based ingestion
• Experience with a cloud data lake/lakehouse, Medallion patterns, schema/interface contracts, data-quality controls, orchestration, observability, and incident recovery
• Solid Git engineering practices: branching, pull requests, reviews, automated tests, deployment controls, and documentation
• Proven ability to translate business/data requirements into filters, mappings, transformations, validation rules, and operational workflows

• Stakeholder-facing problem solving: explain discrepancies, challenge incomplete requirements, establish technical owners, and drive issues to closure.

   

Nice-to-have:

• Strong preference for Azure Data Factory, Azure Databricks, Databricks Jobs/API, Delta Lake, Snowflake, Azure Blob Storage/Data Lake, Power BI, GitHub, and Azure Key Vault
• Valuable experience with Pandera or equivalent schema-validation frameworks, Streamlit, Managed Identity/service principals, Azure Communication Services, Managed VNet/Private Endpoints, and Dev/Prod release practices
• Experience with PFME/media data, syndicated sales, marketing hierarchies, MMM inputs, or multi-market data onboarding is preferred but can be learned.
