• Define and drive the Enterprise Audit roadmap in partnership with Product, Security, Compliance, and other engineering teams—balancing customer value, compliance requirements, and platform sustainability.
• Own architecture and delivery of highly reliable, secure, and scalable audit systems, including event capture, processing, storage, and query/reporting at enterprise scale.
• Build audit as a platform capability with strong guarantees (integrity, durability, tamper resistance, and clear schemas), enabling other teams to emit and consume auditable events consistently.
• Embed security and privacy into everything (least privilege, encryption, defensible access patterns, data minimization, and clear retention/deletion behaviors).
• Establish operational excellence: SLIs/SLOs, monitoring, incident response, capacity planning, and on-call health for audit services.
• Coach and develop engineers and leads, creating a strong culture of ownership, high-quality delivery, and continuous improvement.
• Communicate clearly and proactively with stakeholders and leadership on progress, tradeoffs, risks, and outcomes.
  
  

What You Will Achieve in Your First 360 Days

• First 30 days: Understand current audit capabilities, event sources, data flows, and customer requirements; build strong relationships with Security/Compliance and key partner teams.
• 60–90 days: Clarify the technical and product roadmap, improve team execution, and introduce/strengthen best practices for audit event quality, reliability, and operational readiness.
• 6 months: Deliver meaningful enterprise audit improvements (e.g., expanded coverage of auditable actions, improved exportability, stronger retention controls, or better performance at scale) with measurable customer and operational impact.
• 360 days: Establish a durable Enterprise Audit foundation—scalable, secure, and extensible—positioning Smartsheet as a trusted platform for regulated and security-conscious enterprises.
  
  

You Have

• 10+ years in software development, including experience building distributed systems and production services at scale.
• 5+ years managing engineering teams with a strong track record of coaching, delivery, and talent development.

• Proven ability to partner cross-functionally, align priorities, and deliver through ambiguity.
• Strong Agile delivery habits and a pragmatic approach to balancing speed, quality, and long-term maintainability.
• Legally eligible to work in Bulgaria on an ongoing basis.
• Fluency in English is required.

About Us: 

Delasport is where technology meets the excitement of sports and gaming! As a leading powerhouse in iGaming software, we provide everything from sports betting to online casinos and player account management. Our platform is designed to make every player feel like the star of the show, with personalized experience and cutting-edge technology at its heart.   

Since 2010, we've made a significant impact in industry, earning awards and expanding our global presence. With offices in Bulgaria, Ukraine, and Malta, our team of over 500 experts is constantly driving innovation and striving for excellence. 

About the Team:

The Product Launch team is built for people who don’t just maintain systems but create them. We take products from zero to hero, and scale them until they’re strong enough to be handed over to core teams. No legacy constraints. No endless support cycles. Just greenfield builds, modern tech, and real ownership from day one. 

We move fast, think lean, and execute with focus, one product at a time, full commitment, full impact. Every sprint matter, every decision ship value. This is not a support team. It’s a build-from-scratch engine for products that matter, because every hero needs a superhero.

What You’ll Do:

• Technical Quality Ownership - Set and enforce technical standards for code quality, testing practices, deployment procedures, and observability across all teams. Ensure deliverables consistently meet company and industry standards. 

• Security & Compliance - Champion security best practices in application design and delivery. Drive secure coding standards, dependency management, and vulnerability remediation across the development lifecycle. 

• Technology Decisions - Drive and consult on technology choices in collaboration with the Architect and engineering teams. Evaluate new tools, frameworks, and patterns with a clear focus on efficiency, maintainability, and long-term sustainability. 

• Architecture & Design Guidance - Review and guide system designs, API contracts, data models, and integration patterns. Ensure business requirements are implemented following sound architectural principles and established standards. 

• Hands-On Engineering - Stay deeply hands-on with production code. Lead by example in modern Java (21/25), Spring Boot 3/4, PHP, Laravel, NodeJS, Kafka Streams, and cloud-native microservices. Conduct in-depth code reviews and contribute to critical path development. 

• Observability & Operational Excellence - Define and drive observability standards (metrics, logging, tracing, alerting) to ensure production systems are transparent, diagnosable, and reliable. 

• Technology Adoption - Drive the adoption of new technologies and practices across teams. Build proof-of-concepts, define migration paths, and ensure smooth rollouts with minimal disruption. 

• Cross-Team Collaboration - Act as the technical mediator between Java teams, Team Leads, the Architect, and business stakeholders. Translate business requirements into sound technical guidance and ensure alignment across all parties. 

• Knowledge Sharing - Foster a culture of technical excellence through design reviews, tech talks, documentation, and hands-on mentoring of senior engineers. 

Employees may be required to participate in an on-call rotation, ensuring availability outside regular working hours to respond to urgent issues as needed as per the On call policy.

Who You Are:

Experience: 7+ years of hands-on backend development with strong expertise, including 2+ years in a technical leadership capacity (Tech Lead, Principal Engineer, or equivalent). 

Technical Expertise: 

• Deep knowledge of Java (21+), PHP or NodeJS concurrency, JVM internals, and performance characteristics 
• Strong experience with building production-grade microservices 
• Strong expertise with Kafka and Kafka Streams — event-driven architectures, stream processing, schema evolution, and exactly-once semantics 
• Solid understanding of REST API design principles and synchronous integration patterns 
• Hands-on experience with Kubernetes, GitOps (ArgoCD, Kustomize), and container orchestration 
• Experience defining and implementing observability strategies (metrics, distributed tracing, structured logging, alerting) 
• Strong understanding of application security practices, secure coding, and dependency management 
• Solid database knowledge: relational and document databases, data modeling, and performance tuning 

Soft Skills: Excellent communicator who can translate between technical and business language. Comfortable presenting ideas, challenging decisions constructively, and building consensus across teams. 

Collaboration: Proven ability to work effectively with Architects, Team Leads, Product, and DevOps in a cross-functional environment. 

Mindset: Ownership-driven, pragmatic, and passionate about engineering excellence. You care as much about maintainability and operational quality as you do about shipping features. 

Nice to Have: 

• Experience in iGaming, Sportsbook, or real-time transaction-heavy systems 
• CDC architectures (Debezium) 
• Redis or distributed caching strategies 
• Performance tuning and benchmarking (JMH, async-profiler, JFR) 
• Architecture patterns such as DDD, CQRS, or Event Sourcing 
• Contributions to open-source projects 

What We Offer: 

We’re not just about work,  we are about creating a great place to grow, connect, and enjoy the journey. Here’s what you can expect when you join us:

• Competitive Salary Package: We value your skills, dedication, and contributions
• Time Off: Enjoy 21+ days of annual paid leave so you can rest, recharge, and come back inspired
• Bonus & Rewards: Performance-based annual bonuses, special vouchers for birthdays and welcoming a newborn

If you're excited to join a team that's revolutionizing the iGaming world and want to make a real impact, apply today. We can't wait to meet you! 

About Us: 

Delasport is where technology meets the excitement of sports and gaming! As a leading powerhouse in iGaming software, we provide everything from sports betting to online casinos and player account management. Our platform is designed to make every player feel like the star of the show, with personalized experience and cutting-edge technology at its heart.   

Since 2010, we've made a significant impact in industry, earning awards and expanding our global presence. With offices in Bulgaria, Ukraine, and Malta, our team of over 500 experts is constantly driving innovation and striving for excellence. 

About the Role:

We are looking for a hands-on Java Team Lead to own and evolve the backend architecture of our Sportsbook platform.

This is a technical leadership role combining architectural ownership and active development. You will lead a strong backend team while designing and scaling mission-critical, real-time betting systems operating under extreme load and strict consistency requirements.

This is not a coordination role - you will directly influence system design, performance, and long-term platform evolution.

This role is based in Sofia, Bulgaria, and we welcome candidates who are open to relocating (relocation support provided).

What You’ll Do:

• Architectural Ownership - Own and evolve the backend architecture, designing scalable, high-performance distributed systems while leading key decisions around microservices, messaging, data consistency, and long-term technical sustainability.
• End-to-End Responsibility - Drive the full software lifecycle and take ownership of production systems, ensuring reliability, performance, monitoring, and operational excellence.
• Event-Driven & Streaming Systems - Lead the Kafka-based event architecture, building high-throughput, low-latency pipelines with strong guarantees around consistency, schema governance, and resilience under heavy load.
• Hands-On Engineering - Actively develop critical services in modern Java (21+), reviewing complex code and maintaining high standards in architecture, quality, and maintainability.
• Data & Performance - Design and optimize transactional and distributed data models (MySQL, MongoDB), ensuring consistency and eliminating performance bottlenecks.
• Team Leadership - Lead and mentor backend engineers, drive technical excellence through design reviews, and collaborate closely with Product and DevOps.

Employees may be required to participate in an on-call rotation, ensuring availability outside regular working hours to respond to urgent issues as needed as per the On call policy.

Who You Are:

• Experience: 7+ years of hands-on backend development with strong Java expertise, including 2+ years leading technical initiatives or engineering teams. 
• Technical Expertise: 
  • Deep knowledge of modern Java (21+), concurrency, JVM, and system design
  • Experience building scalable, high-availability, cloud-native microservices
  • Strong expertise with Kafka and event-driven architectures (stream processing, schema evolution, contract-first messaging)
  • Solid database knowledge: MySQL (transactions, tuning), MongoDB, distributed consistency models
  • Familiarity with Docker, Kubernetes, CI/CD, and observability practices
• Soft Skills: Strong communicator, fluent in English, 
• Mindset: Ownership-driven, proactive, and comfortable in fast-paced environments. 

Nice to Have: 

• Experience in iGaming, Sportsbook, or real-time transaction-heavy systems. 
• CDC architectures (Debezium)
• Redis or distributed caching
• Monolith-to-microservices modernization experience
