Sr. Staff Full Stack Software Engineer – Infrastructure Platforms
At Cision, we build software that supports large-scale, global enterprise infrastructure. Our teams enable platform, operations, and engineering groups with tools that improve visibility, reliability, automation, and decision-making across complex systems.
We are seeking a Staff Full Stack Software Engineer to lead the design and delivery of internal platforms used by enterprise infrastructure teams. This is a senior individual contributor role for an engineer who thrives in ambiguity, works independently, and owns systems end-to-end—from architecture through production operations.
You will operate as a technical leader within the team, influencing design decisions, setting engineering standards, and delivering high-impact solutions across backend services, data pipelines, and user-facing applications.

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're hiring a Team Lead for one of the most consequential engineering teams at Delasport - the team that owns KYC, AML, anti-fraud, and regulatory compliance across the platform.
These aren't peripheral services. They're what makes it legally possible for our operators to take a bet in every market we're licensed in. Every player who signs up, every withdrawal, every suspicious pattern, every regulator report - it flows through systems your team owns. When a new jurisdiction comes online, your team is on the critical path.
If you want a leadership role where the work is technically real, the stakes are visible, and the autonomy is genuine - read on.
This role is based in Sofia, Bulgaria and we welcome candidates who are open to relocating (relocation support provided).
What Your Team Owns
You'll lead a team of 5 full-stack developers and 2 QAs responsible for:
- KYC - identity verification pipelines, document checks, and third-party provider integrations
- AML - transaction monitoring, sanctions and PEP screening, suspicious-activity detection
- Anti-Fraud - behavioural analysis and fraud-pattern detection across player activity
- Regulatory Compliance - jurisdiction-specific rules, reporting obligations, and operator configurations
The footprint is a mix of synchronous APIs, scheduled jobs, and real-time stream consumers processing events off Kafka and RabbitMQ.
What You'll Actually Work On
- Shaping the future stack. Today the team works across PHP/Laravel, Python, and TypeScript/Vue. All new services will be written in Node.js, and you'll be a key voice in shaping how that evolution unfolds - patterns, shared libraries, deployment standards.
- Driving technical excellence. Setting and raising the bar on performance, reliability, and operational maturity across the team's services.
- Real ownership of production. The team owns its services end to end - design, build, ship, observe, fix. You set the standard for how that ownership is exercised.
- Growing the team. Seniors ready to push toward staff-level work; mids ready to grow into seniors. Your impact on them will be one of the most rewarding parts of this role.
What You’ll Do
- Lead the team. Set technical direction, code-quality bar, and architectural standards. Run code reviews that teach. Develop the engineers under you.
- Stay hands-on. This is not a pure people-management role. You'll write code, design systems, and pair on hard problems.
- Architect for the real world. Design services that handle real-time event streams reliably, fail safely under regulatory scrutiny, and integrate cleanly with the third-party providers we depend on.
- Drive the technical roadmap. Make and defend the calls on what to refactor, what to rewrite, and where to invest the team's time.
- Partner across the org. Work closely with Product, DevOps, Data, and the Compliance/Legal side of the business - the last of which is unusual for an engineering role and one of the more interesting parts of the job.
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.
Why This Role Is Different
- High business impact. When KYC breaks, players can't deposit. When AML breaks, we have a regulatory problem. The work matters and people know it.
- Polyglot by design, not by accident. PHP, Python, TypeScript today; Node.js for everything new. If you're tired of being pigeonholed in one language, this team doesn't do that.
- Genuine ownership. Your team owns its services end to end. No throwing things over the wall.
- Regulated-domain depth. You'll learn how iGaming compliance actually works at the engineering level - a specialisation that's genuinely valuable and surprisingly rare on the market.
Who You Are
- Experience: 7+ years building backend systems in PHP, including 2+ years leading a team or operating as a senior technical lead.
- Core technical strength:
- Strong PHP and OOP fundamentals - design patterns, clean architecture, testability.
- Production experience with Laravel (or strong Symfony experience and the willingness to ramp on Laravel).
- Comfortable working with event-driven systems - Kafka, RabbitMQ, or equivalent. You've built and operated consumers, not just published a message once.
- Solid grasp of relational databases (MySQL/PostgreSQL) - schema design, query performance, the things that bite at scale.
- Working experience with NoSQL (MongoDB, Redis, Elasticsearch, or similar) - knowing when to reach for it and when not to.
- Comfortable with Docker, containerised deployments, and at least one cloud (AWS, GCP, or Azure).
- Architecture sense: You can reason about scalability, fault tolerance, and failure modes - and explain trade-offs to people who don't share your background.
- Leadership: You lead by setting direction and raising the bar of those around you, not by managing tickets. Strong written and spoken English.
- Mindset: Pragmatic, bias toward shipping, comfortable with ambiguity, genuinely interested in the business problem and not just the technical one.
Nice to Have
- Experience in iGaming, fintech, or any regulated domain (banking, payments, healthcare).
- Hands-on experience with KYC/AML/fraud-prevention systems or vendor integrations.
- Working knowledge of Python and/or Node.js.
- Exposure to TypeScript/Vue or another modern frontend stack.
