Lead Software Engineer @MerciYanis

Join MerciYanis as a Lead Software Engineer, where you will lead product delivery, design and maintain scalable infrastructure, and spread good engineering practices across the team. You will work closely with product engineers and the CTO to ensure our systems meet and exceed customer expectations. The position offers flexible hours, remote work options, and an attractive salary package.

• Lead product delivery by ensuring deadlines are met and quality is high, with scalable solutions and clear specifications.
• Design, build, and maintain scalable, highly available, and fault-tolerant infrastructure to support web services.
• Spread good engineering practices across the team through code reviews, pair programming, documentation, and mentoring of junior engineers.
• Master’s degree in Computer Science, Engineering or a related field
• **7+ years** of professional experience in software engineering, with significant experience **building and scaling SaaS products**
• Excellent problem-solving and communication skills
• Self-motivated and able to work well in a fast-paced startup environment
• Proven experience designing and operating **distributed systems** or **cloud-native architectures** at scale
• A strong background in **observability** (OpenTelemetry, Grafana, etc.)
• Experience with **IoT systems** or real-time data processing is a plus

**Expected Mindset**

• **Take initiative** — you don’t wait to be told what to do. You see a problem, you fix it. You see an opportunity, you propose it.
• **Impact over output** — you measure your work by what it changes, not by how many lines you ship. You focus on what matters most.
• **Rigorous** — you deliver what you promise, and you hold others to the same standard. Details matter to you.
• **Autonomous** — you can take a loosely defined problem, break it down, and drive it to completion without hand-holding.
• **Ownership** — when something breaks, you fix it first and post-mortem later. You feel personally responsible for the product.
• **Execution excellence** — you care about doing things right. “Good enough” is not in your vocabulary when it comes to shipping software.

• If you’re excited about this opportunity but don’t check every box, we’d still love to hear from you. We look for talent above roles — feel free to apply!
