We are looking for a hands-on AI Social Media & Growth Manager who can build and manage our social media presence, create high-quality content using modern AI tools, and help grow the HBDCard brand.
 

This is not a role for someone who only schedules posts or follows a basic monthly content plan.
 

We need someone who understands social media culture, knows how to use AI tools at a high level, can move fast, test ideas, follow trends, and turn them into engaging content.
 

Responsibilities:
 

• Manage HBDCard social media channels: X / Twitter, Instagram, TikTok, LinkedIn, Telegram

AI tools:
 

You should be comfortable working with modern AI tools such as ChatGPT, Claude, Midjourney or other AI image generators, Kling, Google Veo, Seedance, Runway, ElevenLabs, HeyGen, CapCut, and similar tools.
 

We do not expect you to use every tool. What matters is that you understand how to combine AI tools into an efficient workflow and consistently produce high-quality content.
 

Requirements:
 

• 2+ years of experience in social media, content, growth, or a related role
   
• Strong practical experience with AI content-generation tools
• Strong understanding of Instagram, TikTok, X / Twitter, LinkedIn, and short-form video
   
• Good visual taste and understanding of modern social media content
   
• Ability to create content independently without requiring a designer for every post
   
• Strong written English
   
• Ability to write strong hooks and natural copy that does not feel generic or obviously AI-generated
   
• Understanding of social media analytics and content performance
   
• Ability to work independently and take ownership of the social media direction
   
• Fast execution and willingness to experiment
• Ability to identify trends and quickly turn them into relevant content
   

Big advantage if you have experience with:
 

• Crypto / Web3
   
• Fintech
   
• Crypto cards or payment products
   
• Growing X / Twitter accounts in the crypto space
   
• Telegram communities
   
• Organic social media growth
   
• Influencer or creator collaborations
   
• Short-form video production
   
• Video editing or motion design

We are not looking for someone whose main workflow is simply creating a fixed number of posts per month and scheduling them.
 

We want someone who actively looks for opportunities, understands trends, generates ideas, produces content, tests it, analyzes results, and improves quickly.
 

Working format:
 

• Full-time
• Long-term cooperation
• Direct communication with the HBDCard team

We are looking for a Lead DevOps / Observability Engineer to lead the migration of the client's observability stack from New Relic and Datadog to Grafana, using technologies such as Prometheus, Loki, and Tempo.

This is a hands-on role combining:
- DevOps & platform engineering - deploying and configuring the new observability stack using AWS, Kubernetes, and Terraform.
- Application instrumentation - modifying application code to add or adapt metrics, logs, and traces.
- Migration & collaboration - rebuilding existing dashboards and alerts in Grafana and working with multiple engineering teams to ensure full monitoring coverage.

We are looking for someone who is comfortable working across both infrastructure and application code and can independently drive a cross-team observability migration.

Responsibilities:

• Lead the migration of monitoring, alerting, and dashboards from New Relic and Datadog to Grafana.
• Design and implement the target observability architecture (metrics, logs, traces) and the infrastructure-as-code (Terraform) needed to support it.
• Audit existing New Relic and Datadog dashboards, alerts, and integrations to build a complete migration inventory and ensure feature/coverage parity in Grafana.
• Make application-level code changes across services to add, adjust, or replace instrumentation (metrics exporters, logging, tracing libraries) as needed for the new stack.
• Work with AWS infrastructure, including EKS, Kubernetes, and Docker, to deploy and operate the new observability tooling.
• Configure AWS networking and access as needed to support the observability platform (VPCs, security groups, IAM).
• Contribute to CI/CD pipelines and deployment automation using GitHub Actions to support the rollout.
• Collaborate with development, platform, and infrastructure teams to coordinate the cutover from New Relic/Datadog to Grafana with minimal disruption.
• Identify and remediate any security issues (secrets, keys, dependencies) encountered in the course of this work.
• Document the new observability architecture, migration procedures, and dashboard/alert mappings.
• Use AI-assisted development tools, including Codex, to improve engineering productivity and delivery speed.

Requirements: 

• Strong hands-on experience with Grafana, including dashboard design, alerting, and data source configuration (e.g. Prometheus, Loki, Tempo, or similar).
• Practical experience migrating away from commercial observability platforms such as New Relic and/or Datadog.
• Full-stack development experience — comfortable reading, modifying, and instrumenting application code across front-end and back-end services, not just infrastructure.
• Solid experience with AWS in production environments, including EKS and Kubernetes.
• Practical experience with Docker and containerized workloads.
• Strong Terraform and infrastructure-as-code skills.
• Experience with GitHub Actions or comparable CI/CD tools.
• Ability to work across multiple teams, services, and codebases to coordinate a cross-cutting migration.
• Fluency with Codex or comparable AI-assisted coding tools.

Nica to have:

• Prior experience running a similar New Relic/Datadog-to-Grafana (or equivalent) observability migration end to end.
• Grafana-specific certifications or demonstrated community contributions (plugins, dashboards, etc.).
• Experience with the broader Prometheus/Loki/Tempo (LGTM) ecosystem.
• AWS certification, such as AWS Solutions Architect Associate/Professional.
• Experience with RDS and other AWS data services.
• Prior contract or consulting experience with clearly defined deliverables.
• At least an Upper-Intermediate level of English 

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Personalized career growth
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
