About Klik

Klik is a technology services company delivering custom software development, application modernization, and ongoing technical support to clients. We hire senior, dependable engineers who can own their work, communicate clearly, and build long-term trust with both our team and our clients.

About the Role

Senior ColdFusion Developer will join our team on a long-term contract basis and support a key client engagement. You will be the lead hands-on developer on a custom ColdFusion web platform that serves a large, distributed user base, with role-based access for end users, regional officers, executive committees, and administrative staff.

The platform sits on top of a Microsoft SQL Server back end and supports an active queue of new features, form updates, reporting needs, and bug fixes.

Key Responsibilities

• Develop, maintain, and enhance an existing production ColdFusion web application.

• Design and build new pages, web forms, and submission workflows based on business requirements.

• Write and optimize T-SQL queries and reports against a Microsoft SQL Server back end, including data exports to Excel.

• Investigate, diagnose, and resolve bugs and production issues.

• Coordinate with the client’s in-house database team for any schema or data changes.

• Contribute to source control discipline using Git / GitHub, including branching, pull requests, and code review.

• Communicate clearly and professionally with client stakeholders in English, both in writing and on calls.

Required Qualifications

• 5+ years of senior-level hands-on Adobe ColdFusion / CFML development experience on production web applications.

• Strong Microsoft SQL Server and T-SQL skills: complex queries, joins, stored procedures, and basic performance tuning.

• Solid front-end fundamentals: HTML, CSS, and JavaScript; comfortable with form-heavy, role-based web applications.

• Hands-on experience with Git and GitHub (or GitLab) for source control and collaborative development.

• Excellent written and spoken English — able to read tickets independently, ask clarifying questions, and present status confidently.

• Self-directed senior mindset — able to take a well-written ticket and deliver without needing day-to-day hand-holding.

• Disciplined, production-aware engineer — careful with changes on live systems and methodical about verification.

• Reliable internet connection and a professional remote working setup.

• Available to work US Eastern Time business hours through at least 2:00 PM EST every working day (from 12.00 to 20.00 Kyiv time).

Preferred Qualifications

• Experience supporting non-profit, membership, or association-based organizations.

• Experience modernizing or migrating legacy ColdFusion applications to modern stacks such as .NET, Node.js, or Java.

• Experience working in environments with limited test infrastructure, where production discipline matters.

• Familiarity with Smartsheet, Jira, or other sprint / work-management tools.

• Prior experience working remotely with US-based clients on long-term engagements.

What We Offer

• A long-term, stable contract engagement (12+ months expected) with steady weekly hours.

• Approximately 30–40 hours per week initially, with the ability to flex based on workload.

• Direct ownership of meaningful, visible work — not commodity ticket churn.

• Supportive technical onboarding from an experienced developer already on the project.

• A clear, well-managed backlog with regular planning cadence.

• Opportunity to influence longer-term platform modernization decisions.

• Fully remote work; no travel required.

How to Apply

About the Role:

We are looking for an AI Enablement Specialist — a highly proactive, cross-functional professional who will help us rethink how digital products are built, delivered, and scaled using AI.

This is not a traditional engineering or design role. Instead, we’re looking for someone who understands product development holistically — spanning business, design, and engineering — and can identify, test, and implement  AI-driven approaches that significantly improve speed, quality, and innovation.

You will play a key role in shaping how we adopt AI across workflows, from early prototyping to delivery and even sales enablement.
 

Key Responsibilities:

— Drive AI adoption and modernization across product development processes.

— Identify, test, and implement AI-powered tools and workflows to accelerate delivery.

— Actively participate in brainstorming, product discussions, and strategic decisions.

— Propose new approaches and ideas — including those the team hasn’t yet even considered.

— Facilitate strong cross-team communication between business, design, and engineering.

— Prototype solutions using modern AI tools instead of traditional workflows where applicable.

— Continuously explore and evaluate emerging AI tools and methodologies.

— Build and showcase real use cases demonstrating efficiency gains and improvements.

— Support client-facing activities and sales, helping articulate AI-driven value propositions.

— Educate and guide teams on how to effectively leverage AI in their daily work.
 

What We’re Looking For:
— Proven examples of process optimization or innovation using AI.
— Strong understanding of digital product development (across design, engineering, and business).
— Experience and deep interest in AI-enabled workflows and tools.
— Experience in pre-sales, consulting, or client interaction.
— A self-starter mindset — someone who brings ideas, not just executes tasks.
— Excellent communication and facilitation skills.
— Curiosity and drive to continuously explore, experiment, and improve.
— Ability to translate complex ideas into clear, actionable insights.
— Understanding of how businesses operate and how technology drives value.
— Experience with rapid prototyping and modern tools (LLMs, AI copilots, no-code/low-code platforms, etc.).
 

What Success Looks Like:
— Faster product development cycles through AI-driven improvements.
— Tangible examples of efficiency gains and innovation.
— Increased adoption of AI tools across teams.
— Increased number of new clients driven by improved delivery capabilities, visible innovation, faster execution, and AI-powered value delivery.
— New, unexpected ideas that push the company forward.
 

What we offer for you to succeed:

— Warm and friendly working environment with flexible start (from 8:00 to 11:00) based on personal preferences and team meetings.

— We put a healthy work-life balance first.

— Caring for physical and mental health.

— Speaking Club and English with a teacher.

— Volunteer projects that help the state get closer to victory.

— A space to grow both professionally and personally. A wide variety of exciting projects, the best hardware for your work, performance reviews, educational workshops, and team coaching.

— No tiresome bureaucracy. If you need something — just ask and get it.
 

Our employees describe working here as a welcoming, collaborative, and impactful experience. If you are a creative and energetic person, we cannot wait to see you on board!

• Maintain and evolve CI/CD pipelines and infrastructure-as-code practices
• Collaborate closely with engineering teams to support deployments and minimise user impact in a live environment
• Introduce and integrate new tools and technologies to enhance scalability, reliability, and performance
• Handle environment-specific requests and ensure smooth day-to-day platform operations under constant load

Requirements

• Strong hands-on experience with Kubernetes (deployment, scaling, troubleshooting) in high-load environments
• Experience with GitOps tools such as FluxCD or ArgoCD
• Proven experience in incident response, root cause analysis, and postmortems in production systems
• Solid experience with AWS, Terraform, Docker, and CI/CD pipelines
• Experience with monitoring and observability tools such as Datadog, Prometheus, Grafana, and logging stacks like ELK or CloudWatch
• Strong understanding of networking concepts and protocols
• Proficiency in at least one scripting language (e.g. Python, Go, Node.js)
• Experience working with version control systems (Git)
• Familiarity with incident management tools like PagerDuty, Opsgenie, or similar
• Ability to operate effectively in a fast-paced, high-pressure environment with strong ownership and accountability
• Proactive, resilient mindset with a focus on continuous improvement and system stability
