Who we're looking for:

Parsec Studio is hiring a Marketing Specialist (Email and LinkedIn outreach) to build and run a systematic cold outreach engine — becoming our primary channel for landing new clients. 

This isn't a one-off email blast. We need someone who can build a full machine: from sourcing and validating leads, to messages that actually get replies, to booked calls on the calendar.

What you'll do

• Build and run a cold email + LinkedIn outreach system, from scratch or on top of existing tools
• Source and validate leads: define ICP, manage list sources, verify emails, segment audiences
• Write and test messaging sequences (email sequences, LinkedIn InMail/connection flows)
• Continuously optimize conversion at every funnel stage (open rate, reply rate, meetings booked)
• Maintain CRM tracking of leads and report on funnel performance

• Work closely with the founder on positioning and value propositions for different niches. 

   

What matters to us

• Proven experience building and running cold email outreach systems (Smartlead, Apollo, Linked Helper, or similar)
• Confident with LinkedIn outreach
• Experience sourcing and validating B2B leads (Apollo, Clay, Hunter, Snov.io, etc.)
• Solid grasp of cold outreach funnel metrics and how to improve each stage

• Flexible schedule, fully remote
• Room to experiment — we're open to new tools and approaches as long as they deliver results

How to apply

Send a short resume + 2–3 examples of campaigns you've built (metrics are welcome more than pretty screenshots). If there's an email you're personally proud of, include it.

We are looking for a Back-End Developer to join our team.

Over the years, we have built well-established work processes, earned an excellent reputation, and successfully delivered around 300 projects. These include custom ERP and CRM systems, healthcare solutions such as Wibbi, web applications such as Exotics Racing, online booking platforms such as WelcomeSaudi, marketplace and review platforms such as NoCowboys, and official medical education platforms such as ExchangeCME.

Requirements:

• 2+ years of experience with PHP, including Laravel;
• Experience with MySQL;
• Basic knowledge of front-end technologies, including HTML5, CSS3, JavaScript, and SASS/LESS;
• Experience with Git and GitFlow;
• ability to work with LLMs;

• Setting up system email notifications;
• Working with API integrations;
• Working with databases, including database design and queries;
• Working with AWS;
• Creating user roles and role-based functionality.

The task pool depends on the specific project.

We work in cross-functional teams consisting of developers, a team leader, a project manager, and a QA engineer. We do not simply execute client tasks — we provide solutions and offer consulting.

For every project, it is important to contribute not only to the architecture and code but also to the client’s business by playing an active role in the project’s development. This means being ready to propose solutions for various business challenges the client may face.

For example, one of our clients had not received their payment system API key and was unable to process payments on Black Friday. We urgently implemented an “order” feature that allowed their customers to place orders at discounted prices and pay later.

If you are interested in this position, we would be happy to discuss it in more detail.

We are seeking a hands-on Senior DevSecOps Engineer with strong AWS and Azure experience to embed security directly into our engineering lifecycle.

·  Security Product Deployment: Automate the baking of EDR agents, vulnerability scanners, and monitoring tools into base machine images (AMIs, Azure Golden Images) and containerized base environments.

·  Vulnerability & Remediation Pipelines: Operationalize vulnerability management by building automated workflows that ingest findings from cloud security tools, prioritize them based on risk, and route them to engineering backlogs (e.g., Jira tracking).

·  Developer Enablement: Serve as a bridge between Security and Engineering, providing developer-friendly remediation guidance and creating reusable, secure-by-default code templates (Terraform modules, Helm charts).

Required Skills & Qualifications

·  DevSecOps & CI/CD Pipelines: Deep, practical experience constructing and securing automated build/release pipelines at scale.

·  Multi-Cloud Platforms: Hands-on engineering experience configuring native security services and access controls in both AWS and Azure.

·  Infrastructure as Code (IaC): Advanced proficiency with Terraform or cloud-native tooling (Bicep, CloudFormation), focusing on modular design and immutable infrastructure.
