ARE YOU AN ELITE BACKEND ENGINEER WHO CAN OWN MORE THAN JUST CODE?

At Crebos, we’re not just hiring developers – we’re seeking a Senior Full Stack Developer with exceptional technical expertise, strong leadership abilities, and a business-oriented mindset.

You will own the end-to-end development process, build high-performance applications, mentor developers, and help deliver scalable products that create real value for our customers.

ABOUT US

Crebos is an innovative technology company focused on building high-quality, scalable, and user-driven applications.

We believe in ownership, accountability, customer value, quality, and continuous improvement.

WE ARE NOT LOOKING FOR A REGULAR DEVELOPER

• We are looking for an elite performer.
• A great senior developer isn't measured by how many tickets they close or lines of code they write. We need someone who understands the business problem, customer value, product, quality standards, risks, delivery commitments, and long-term impact of what they build.
• Someone who can take a problem, understand the desired outcome, identify what could go wrong, build the right solution, and take responsibility for delivering it successfully.
• At Crebos, we call these people our Spartans – elite performers who take ownership, raise standards, and make the entire team stronger.

THE MINDSET & TRAITS WE EXPECT

• Business Clarity – Understand why something is being built, the business problem behind it, and what measurable value it should create.
• Success Definition – Define what “done” and successful actually mean before starting.
• Scope Discipline – Understand requirements, dependencies, assumptions, and exclusions while preventing unnecessary complexity and scope creep.
• Extreme Ownership – Own outcomes end-to-end. Don't hide behind roles, teams, or tickets. Escalate blockers early and follow problems through to resolution.
• Risk Awareness – Identify technical risks, dependencies, edge cases, security concerns, performance issues, and potential blockers before they become problems.
• Delivery Predictability – Make realistic commitments, communicate deviations early, and consistently deliver against a clear definition of done.
• Systems Thinking – Fix root causes, not symptoms. Build scalable, maintainable, reusable solutions and avoid unnecessary technical debt.
• AI Leverage – Use AI effectively across development, debugging, testing, research, documentation, code reviews, automation, and problem-solving to measurably improve speed and quality.
• Continuous Improvement – Turn lessons, failures, and feedback into better standards, processes, automation, and reusable solutions.

CUSTOMER, PRODUCT & QUALITY MINDSET

• Your responsibility doesn't end when the code works.
• You should constantly think:
• What problem are we solving?
• What value does this create for the customer and business?
• What experience will the customer have?
• What could fail?
• Are we solving the root problem?
• Can we achieve the same outcome with less complexity?
• Is the solution secure, scalable, maintainable, performant, and production-ready?
• We expect strong standards around architecture, clean code, scalability, performance, security, automated testing, error handling, edge cases, code reviews, documentation, technical debt, and customer experience.

KEY RESPONSIBILITIES

For this role, “it works on my machine” is not acceptable.

You should understand and be able to troubleshoot the complete production journey:

Code → Build → Docker → CI/CD → Google Cloud → Kubernetes → Server → Database → Network → Monitoring → Production

We expect strong knowledge of:

• Backend architecture, system design, scalability, and high availability

• REST APIs, microservices, asynchronous and event-driven architecture

• MongoDB, MySQL/PostgreSQL, database design, indexing, and optimization

• Docker and Kubernetes

• Google Cloud Platform (GCP)

• Linux servers and server administration

• Nginx, reverse proxies, load balancing, SSL/TLS, DNS, networking, firewalls, and server security

• Redis, caching, queues, background workers, and asynchronous processing

• Authentication, authorization, API security, secrets management, and data protection

• CI/CD, automated deployments, logging, monitoring, alerting, and observability

• Performance optimization, failure recovery, scalability, and production reliability

You should be capable of independently investigating slow APIs, high CPU/memory usage, Kubernetes pod failures, failed deployments, database bottlenecks, 502/503 errors, service communication failures, and scaling issues.

We don't expect you to hand every infrastructure issue to DevOps. You should understand the complete system, investigate problems independently, collaborate effectively, and own the issue until resolution.

WHAT WE’RE LOOKING FOR

• 5+ years of strong backend development experience, with substantial production experience using Node.js.

• Strong expertise in Node.js and JavaScript/TypeScript.

• Deep understanding of asynchronous programming, event-driven architecture, REST APIs, microservices, and distributed systems.

• Strong experience with MongoDB, MySQL and/or PostgreSQL, including database design, indexing, transactions, and query optimization.

• Strong hands-on experience with Docker and Kubernetes, including deployments, services, pods, scaling, health checks, and troubleshooting.

• Hands-on production experience with Google Cloud Platform (GCP).

• Strong debugging and root-cause problem-solving abilities.

• Proven ability to own complex technical problems from architecture through production.

• Strong product, customer, and business understanding.

• Practical experience using AI and modern engineering tools to improve development speed, debugging, automation, productivity, and quality.

• Strong communication, teamwork, mentoring, and technical leadership skills.

• Bachelor's degree in Computer Science, Engineering, or a related field is preferred.

WHY JOIN CREBOS?

At Crebos, you’ll get an environment, platform, responsibility, and level of exposure designed to accelerate your growth beyond what you would typically experience in a conventional development role.

We believe exceptional people grow fastest when surrounded by other high performers, given meaningful ownership, and challenged with real business problems.

• High-Performance Environment – Work with ambitious people who value ownership, accountability, speed, customer value, and quality.
• Exceptional Growth Platform – Accelerate your technical, leadership, product, business, and professional growth.

IMPORTANT NOTICE

• This role carries significantly higher expectations than a conventional development position.

• We expect technical excellence, ownership, business thinking, customer orientation, predictable delivery, AI leverage, and continuous improvement.

We are not building an average development team. We are building a team of Spartans.

People who take ownership. Understand the business. Care about the customer. Think before they build. Identify risks early. Deliver what they commit to. Use AI and technology to multiply their impact. And continuously raise the standards of themselves and everyone around them.

If you are looking only for a comfortable development job where you receive requirements, complete tickets, and move on, this may not be the right role for you.

But if you want to challenge yourself, accelerate your growth, take real ownership, and become an exceptional engineer and leader, Crebos will give you the platform to do it.
