Full-Stack Staff Software Engineer

We’re looking for a hands-on Staff Software Engineer / Tech Lead to provide technical leadership for our Price Optimization and Management solutions team in Sofia. The team develops and evolves a family of enterprise pricing products across both monolithic and microservices architectures. You will be responsible for setting the technical direction of our products, translate product strategy into actionable engineering plans, and help the team deliver secure, scalable, and reliable solutions. This is a technical leadership role, not a people-management position.

Here’s what will give you an edge…

• Own the technical design and the evolution of product functional areas and services, making pragmatic decisions that balance customer value, delivery cost, maintainability, security, performance, and risk.
• Translate product strategy and roadmap priorities into clear technical approaches, actionable increments, dependencies, estimates, and delivery plans for the team.
• Lead design discussions across application, service, data, and deployment boundaries, build consensus, and document important architectural decisions and trade-offs.
• Remain hands-on by designing and implementing critical Java services, REST APIs, business logic, data-access components, and selected React and TypeScript features.
• Design and evolve SQL and NoSQL data solutions, covering data modeling, schema evolution, data-access patterns, performance, scalability, and safe migrations.
• Guide the team toward simple, consistent, and secure designs, reinforcing engineering practices through reviews, examples, and constructive technical challenge.
• Mentor Senior Software Engineers and other team members through pairing, design reviews, code reviews, and knowledge sharing.
• Drive engineering quality through automated unit, integration, and end-to-end testing, observability, production readiness, and continuous improvement.
• Lead the technical investigation of complex production incidents, identify root causes through systematic debugging, and drive sustainable corrective and preventative improvements.
• Collaborate proactively with Product, QA, Cloud Operations, Security, Architecture, and adjacent engineering teams to resolve dependencies and deliver cohesive outcomes.
• Identify technical risks, blockers, and unhealthy patterns early, communicate them clearly, and propose practical alternatives before delivery is at risk.

A proven track record…

• 7+ years of related software engineering experience, including cloud technologies and technical leadership within a complex product environment.
• Deep Java backend expertise and strong hands-on experience with object-oriented design, design patterns, SOLID principles, APIs, distributed systems, and microservices architecture.
• Full-stack breadth, with practical experience in modern front-end engineering, preferably React and TypeScript, and the ability to guide decisions across the application stack.
• Deep understanding of automated testing, systematic debugging, production diagnostics, observability, and secure software-engineering practices.
• Experience owning the design and operation of a functional area or service, including monitoring, production readiness, performance, scalability, and operational risk.
• Experience with large relational and NoSQL data stores, data modeling, schema evolution, migrations, and performance optimization.
• Strong analytical judgement and the ability to find answers when they are not obvious, resolve underlying issues rather than symptoms, and make sound decisions amid ambiguity.
• Demonstrated ability to lead through influence, build consensus, facilitate healthy technical debate, and challenge decisions constructively.
• Ability to break down roadmap goals into actionable work, coordinate dependencies and priorities, and help the team deliver predictable outcomes.
• Strong communication and collaboration skills across Engineering, Product, QA, Operations, Security, and senior stakeholders.
• A coaching mindset and proven ability to mentor Senior Software Engineers and help raise engineering standards across a team.
• Hands-on experience integrating AI-assisted development tools, such as GitHub Copilot, Claude, or similar, into professional software-engineering workflows with appropriate review and judgement.

Nice to have

• Experience with data-intensive business domains.
• Experience modernizing a mature monolithic product while introducing or evolving cloud-native microservices.
• Experience with event-driven architectures, large-scale data processing, or analytical data technologies such as Databricks, SQL Server Analysis Services, OLAP, MDX, or DAX.
• Experience leading improvements in architecture, observability, security, CI/CD, testing, or developer productivity.

Our technology landscape

• Backend: Java 21, Spring Boot, Dropwizard, JDBI, Hibernate, Liquibase
• Frontend: React, TypeScript
• Data and messaging: Microsoft SQL Server, Kafka, Cassandra, Databricks, Redis, TiDB
• Analytics: OLAP, MDX, DAX, SQL Server Analysis Services
• Cloud and deployment: Docker, Kubernetes, Helm, Azure
• Delivery: GitHub Actions, Azure DevOps, Jenkins
• Testing: Cucumber, Selenium, Playwright, JUnit
