Job description

Social Discovery Group is a group of social discovery companies. SDG solves the problems of loneliness, isolation, and disconnection - transforming virtual intimacy into the new normal. SDG’s products redefine the way people interact and connect with one another.

Our portfolio includes social entertainment platforms designed to connect people online across different cultures and regions of the world.

We bring together a team of like-minded people and IT professionals who specialize in creating and developing globally impactful social discovery products. Our international team of digital nomads works remotely from all over the world.

We’re proud to be a two-time “Great Place to Work” winner (USA & Japan, 2024–2025) and a Top-5 Company for Work-From-Anywhere Jobs (FlexJobs, 2025).

We are looking for a Team Lead Software Engineer (.NET).

Your main tasks will be:

• Own delivery of the monolith-to-microservices modernization end-to-end — from legacy analysis through production release — with full visibility into pipeline status and risk.
• Partner with Product and Architecture to review specs, map legacy dependencies, and turn that into estimates the team can actually hit.
• Guide architectural decisions across .NET Core services, databases (SQL/NoSQL), and frontend integrations, and be the go‑to for the hardest backend, data migration, and production incident calls.
• Sharpen how the team works day-to-day — tighter task tracking in Jira, more accurate estimation, and a QA partnership that keeps bugs resolved fast and production stable.
• Run regular 1-on-1s tied to real career goals, and drive the feedback and process changes that keep the team improving and engaged.

We expect from you:

• Solid .NET engineering background with deep expertise in C#, .NET 8, and ASP.NET Core.
• Deep understanding of web application architecture, REST APIs, the microservices pattern, message brokers (RabbitMQ), and database design (PostgreSQL, MS SQL Server, Redis).
• Practical experience with legacy system modernization, monorepo-to-microservices refactoring, and containerization (Docker, Kubernetes).
• Ability to act as the technical escalation point for complex implementation, data migration, or performance issues.
• Proven experience managing engineering teams — running 1-on-1s, performance reviews, and objective evaluations.
• Strong track record in delivery management: task tracking in Jira, process discipline, and hitting internal deadlines with predictable releases.
• Experience reviewing business specs, assessing technical feasibility, and providing high-level estimates — partnering closely with PM and product to keep engineering output aligned with product goals.

What do we offer:

• REMOTE OPPORTUNITY to work full-time;
• The initial pay level or pay range for this role will be shared with candidates during the recruitment process and before the commencement of employment;
• Vacation 28 calendar days per year;
• 7 wellness days per year (time off) that can be used to deal with household issues, to lie down and recover without taking sick leave;
• Bonuses up to $5000 for recommending successful applicants for positions in the company;
• 50% payment for professional training, international conferences, and meetings;
• Health benefits. According to the paychecks, if you are not eligible for corporate medical insurance, the company will compensate you with up to $ 1,000 gross per year per employee. This can be spent on self-purchase of health insurance or on doctor’s fees for yourself and close relatives (spouse, children);
• Workplace organization. The company provides all employees with an equipped workplace and all the necessary equipment (table, armchair, wifi, etc.) in our offices or co-working locations. In the other locations, the company provides reimbursement of workplace costs up to $ 1000 gross once every 3 years, according to the paychecks. This money can be spent on the rent of the co-working room, on equipping the working place at home (desk, chair, Internet, etc.) during those 3 years;
• Internal gamified gratitude system: receive bonuses from colleagues and exchange them for our merchandise, team building activities, massage certificates, etc.
