Ця роль поєднує практичну security engineering роботу з hands-on дослідженням і тестуванням. Ви допомагатимете формувати внутрішні стандарти безпеки, захищати критичну інфраструктуру та проактивно виявляти слабкі місця в наших системах до того, як ними зможуть скористатися.

Ми створюємо складні AI systems, що працюють із великими обсягами даних у чутливих середовищах. Саме тому для нас безпека - це не просто вимога комплаєнсу, а повноцінна інженерна дисципліна.

Що ви будете робити

• Проєктувати та впроваджувати політики кібербезпеки й внутрішні стандарти безпеки.
• Допомагати підтримувати контроль і прозорість щодо корпоративних пристроїв, серверів та інфраструктурних активів.
• Будувати та вдосконалювати рішення, що знижують ризик витоку даних і несанкціонованого доступу.
• Проводити внутрішні security assessments наших продуктів, інфраструктури та сервісів.
• Регулярно проводити внутрішні penetration tests і security audits.
• Використовувати такі інструменти, як Nmap, Nuclei, Metasploit та інші scanning frameworks, для виявлення вразливостей.
• Аналізувати потенційні attack surfaces на рівні APIs, web applications, внутрішніх сервісів та інфраструктури.
• Тісно взаємодіяти з engineering teams, щоб виявляти й закривати security issues ще на ранніх етапах розробки.
• Допомагати впроваджувати механізми моніторингу, логування та виявлення підозрілої активності.
• Документувати результати, пропонувати mitigation strategies і допомагати командам впроваджувати необхідні виправлення.

Що нам важливо

• Сильне практичне розуміння принципів кібербезпеки та сучасних attack vectors.
• Hands-on досвід роботи з інструментами security testing, такими як Nmap, Nuclei, Metasploit або подібними frameworks.
• Сильне розуміння network security, web application security та infrastructure security.
• Досвід проведення penetration tests або security research.
• Знайомство з Linux-системами та типовими серверними середовищами.
• Вміння аналізувати системи та виявляти слабкі місця в архітектурі або реалізації.
• Допитливість, наполегливість і сильна внутрішня мотивація розуміти, як саме системи дають збій.
• Вміння налаштовувати та підтримувати system-level firewalls (наприклад, iptables, nftables або ufw) і забезпечувати мережеві політики доступу.
• Досвід налаштування та експлуатації Web Application Firewalls (WAFs), таких як Cloudflare WAF, ModSecurity або подібних рішень, для захисту APIs і web services.
• Сильне практичне розуміння того, як у реальності працює Інтернет, зокрема DNS, TLS, HTTP та типові attack vectors, що впливають на мережеві системи.
• Ґрунтовні знання мережевих основ, зокрема TCP/IP, routing, NAT, VLANs і моделі OSI.

About the Company

Streamline is a fast-growing U.S.-based telecom infrastructure group operating as a prime contractor for major MSOs and ISPs. We deliver end-to-end services — from network construction and deployment to subscriber installations and maintenance — across 16+ states with 400+ field technicians. Our model eliminates the need for multiple vendors by combining OSP construction and fulfillment under a single contract, positioning us as a predictable, full-scope partner for the largest operators in the country.

Role Overview

We’re looking for a Brand Communications Manager to build and execute thought leadership and brand communications for Streamline. This is not an SMM role. The core of the job is working directly with company leadership — CEO, VPs, and operational directors — to extract their expertise, insights, and perspectives, and translate them into compelling content that positions Streamline as a market leader in the minds of decision-makers at major telecom operators. You will also build a proof engine that showcases our daily operations, project wins, and field capabilities to reinforce our brand promise with evidence.

Key Responsibilities

Thought Leadership & Executive Communications

• Develop and manage thought leadership programs for 3–4 key executives (CEO, VPs, operational leaders)
• Conduct weekly interviews and briefings with leadership to capture insights, opinions, and expertise
• Ghostwrite LinkedIn posts, articles, and commentary in each leader’s authentic voice
• Build and maintain a content calendar aligned with industry events, market trends, and company milestones
• Grow executive LinkedIn followings and engagement within the target audience of telecom decision-makers

Proof Engine & Brand Content

• Create and publish case studies, project highlights, and operational proof points that demonstrate company capabilities
• Work with field operations teams remotely to source stories, photos, and video from active job sites
• Develop a systematic content pipeline that turns daily fieldwork into brand-building assets
• Launch and manage a brand ambassador program among field technicians to amplify authentic, ground-level content

Media Relations & Channel Management

• Pitch and place company news, case studies, and executive commentary in telecom industry media and trade publications
• Manage company LinkedIn page as the primary brand channel; develop website content strategy
• Plan and execute phased expansion to Facebook, Instagram, and potentially TikTok as the brand matures
• Track and report on content performance, audience growth, and engagement metrics
   

Qualifications Required

• 3–5 years of experience in B2B content strategy, brand communications, or executive communications
• Proven ability to ghostwrite for executives — portfolio of published thought leadership content required
• Strong interviewing skills: ability to extract compelling narratives from subject matter experts
• Native or near-native English writing skills for a U.S. business audience
• Deep understanding of LinkedIn as a B2B platform (algorithm, formats, engagement strategies)

• Ability to work independently in a remote environment, aligned with U.S. time zones

   

Preferred

• Experience in telecom, infrastructure, construction, utilities, or related B2B industries
• Experience pitching and placing content in trade/industry media
• Familiarity with brand ambassador or employee advocacy programs
• Experience managing multi-channel content strategies (LinkedIn, website, social media)
• Basic understanding of content analytics and reporting tools

Why This Role

• Build a brand from the ground up — you’ll shape how a fast-growing company is perceived by the market
• Direct access to C-level and senior leadership daily — your work has immediate, visible impact
• Real influence over company positioning and market perception, not just content output
• Join a company in a high-growth phase competing for market share in a $100B+ industry
• Remote-first role with autonomy and ownership of the communications function
