Senior Backend Developer (.NET)
Experience: 5+ Years | Location: On-site – Tel Aviv (Midtown) Company: B2C Gaming Startup (Sweepstakes)
About Us
We're a B2C gaming startup building a high-performance sweepstakes platform already serving real users. Our system handles real-time transactions at scale in a regulated space — reliability, speed, and security aren't aspirational, they're table stakes.
We operate lean — there's no dedicated DevOps team — so backend engineers own their services from architecture to production. Engineers here don't just implement — they design, decide, and ship.
The Role
We're looking for a Senior Backend Developer with 5+ years of experience who wants real ownership over systems that matter. This isn't a ticket-taking role — you'll be driving system design, making tech stack decisions, and shaping the architecture of a live, real-money gaming platform.
You'll design and build backend services using .NET 10, own features end-to-end from architecture through production, and work directly with product, business, and compliance stakeholders. You'll be expected to identify the right tool for the job — whether that's choosing between Postgres and MongoDB for a given flow, deciding when WebSockets beat HTTP, or deciding what doesn't need to be built at all.
This is a fully on-site role in Tel Aviv (Midtown).
Responsibilities
- Lead system design and architecture for backend services using .NET 10
- Choose the right tech stack for each problem and justify those decisions
- Architect scalable, secure, and high-performance APIs and real-time systems
- Design data models and flows across PostgreSQL and MongoDB based on access patterns, consistency needs, and scale
- Build real-time gameplay and transaction features using WebSockets and event-driven patterns
- Apply backend best practices: clean architecture, SOLID, KISS, testing, logging, and monitoring — pragmatically, not dogmatically
- Own features end-to-end — from architecture and implementation through deployment, monitoring, and iteration in production
- Manage CI/CD pipelines and AWS infrastructure for the services you own
- Collaborate directly with product, business, and compliance stakeholders to shape what gets built
- Use AI coding agents (Claude Code, Codex, Cursor, etc.) to raise both velocity and quality
Requirements
- 5+ years of backend development experience, with strong fluency in modern .NET (C# / .NET 10+)
- Demonstrated experience owning system design and architecture decisions on production systems
- Strong experience with both PostgreSQL and MongoDB — including schema design, indexing, and choosing between them based on workload
- Experience building real-time systems with WebSockets
- Track record of taking complex features end-to-end: design, implementation, deployment, and production ownership
- Ability to choose and justify a tech stack rather than just consume one
- Strong analytical and problem-solving skills, with a bias toward simple, correct solutions
- Comfortable with full ownership in a lean startup environment — no hand-holding, no hiding
- Experience with or strong willingness to adopt AI coding tools
- Independent, proactive, opinionated, and solution-oriented
Nice to Have
- Experience in gaming, sweepstakes, fintech, or high-scale B2C platforms
- Experience with AWS (ECS, RDS, etc.)
- Experience with message queues and event-driven / asynchronous architectures
- Experience designing for regulated environments (compliance, auditability, PII handling)
What We Offer
- Meaningful ownership over core systems serving real users
- A small, senior team with minimal bureaucracy — decisions get made in hours, not weeks
- Fast-paced environment in one of gaming's fastest-growing verticals
