About the Project

You’ll build and lead a SOC team from scratch for a global SaaS company (unicorn-stage, 20+ offices, Fortune 500 clients). The customer Security team is super strong and the stack is superior. As the first SOC leader (in charge of 6 Tier 2 analysts), you’ll upgrade existing response processes so the internal team can focus on security engineering.

You’re the escalation point for your analysts and the client’s IT, DevOps, and App Security teams, and you own 24/7 coverage, SOC KPIs, and the feedback loop to Security Engineering. This is not a ticket-closing role: you set the tone for how incidents are handled.

What You’ll Do

• Lead the team: run the L2 analysts day-to-day (prioritization, playbooks, escalations), hold team syncs and handovers, and mentor and onboard analysts
• Own 24/7 coverage: build and maintain shift schedules and on-call rotations so the SOC is always staffed
• Own incident response: lead the full lifecycle from triage to closure, coordinate high-severity events and run post-incident reviews
• Investigate hands-on: be the escalation point and work complex alerts alongside analysts, beyond Tier 2 capability
• Measure and report: track team and individual performance and out comes against KPIs and SLAs (MTTA, MTTR, SLA compliance, false positive rate, backlog) and report to management and the client
• Bridge to Security Engineering: turn analyst pain points (false positives, alert fatigue, detection gaps) into detection tuning and improvement suggestions.
• Communicate clearly: work with the client’s security team at technical and managerial level, with honest status updates, including when something is unknown

What You Bring

Hard requirements (non-negotiable):

• 5+ years in SOC / incident response roles, including prior Tier 2/3 analyst experience. Not just monitoring: actual IR ownership
• 2+ years of team lead or management experience in a SOC, including shift lead or mentoring responsibility
• Proven experience building and running 24/7 shift schedules and on-call rotations, and keeping coverage intact in practice
• Proven experience owning SOC KPIs and SLAs (MTTA, MTTR, SLA compliance): you can show how you measured a team and improved it
• Experience leading or coordinating a team during an active incident, and the ability to describe it step by step
• Cloud / AWS security experience: ability to investigate and respond to cloud alerts on day one
• SaaS investigation experience
• SIEM hands-on: Splunk (required), with the ability to write and read SPL queries. CrowdStrike SIEM is a strong plus
• EDR: Microsoft Defender and/or CrowdStrike
• Working knowledge of both Windows and macOS environments
• Strong communication skills, bridging SOC operations and Security Engineering. Intellectual honesty: you say “I don’t know” when you don’t know

Strong plus:

• Identity platforms: Okta, Azure AD
• SOAR automation and threat hunting
• Experience building a SOC at level 4-5 based on SOC-CMM
• Feeding analyst findings into detection engineering (tuning, new detections)

Things that won’t work here

• Only closing alerts without owning the IR process
• Never having owned a shift schedule, on-call rota or KPI reporting
• Managing from the sidelines instead of investigating alongside the team
• Confident wrong answers instead of acknowledged gaps
• No ability to describe team coordination during a real incident

Tech Stack

Splunk · Microsoft Defender · CrowdStrike · Okta · AWS

What We Offer

• Superior technical team and a great customer with massive modern infrastructure
• AI everywhere, with the ability to automate every step: work smarter, not harder
• Real ownership from day one to build the SOC processes, coverage model and KPIs
• Direct collaboration with the client’s senior security team
• Warsaw office (day shifts), with a flexible on-call and night coverage model you design with your team
• Relocation support

You'll work on large-scale cloud infrastructure serving enterprise customers while building automation, improving observability, and enabling engineering teams to deliver software safely and reliably.
• You'll collaborate with a global SRE organization using modern cloud-native technologies, Kubernetes, distributed systems, and large-scale SaaS workloads. You'll have the opportunity to lead impactful reliability initiatives, influence engineering best practices, and solve complex production challenges that directly improve the experience of both customers and engineering teams.

Do you want to make a significant contribution to the victory? Do you want to help win success on the frontline by applying AI to our nation’s drone fleet?

Occam Industries delivers autonomy to the battlefield. We are purely software; we partner with some of the most major OEMs and brigades.

If you want a senior role that still means being one of the best engineers in the business, this is it.

Your Mission

Lead our engineering team to build, integrate, and ship reliable autonomy software to the frontline at speed and scale.

What You’ll Own

• System architecture across our modular autonomy stack.
• Technical direction for the Pilot and Platform engineering teams.
• Hands-on engineering to solve the hardest problems. Expect to spend half of your time in the codebase.
• Working with Product, OEMs and brigades to turn frontline needs into things we can actually build and ship.
• Technical trade-offs across performance, reliability, hardware constraints and speed of delivery.
• Hiring the engineers we need to move faster.

What You Bring

• Deep hands-on engineering — you will need to be credible working in the codebase, not only above it.
• Experience owning system architecture across complex, hardware-adjacent software systems.
• A track record of driving engineering teams to ship, without relying on formal management authority.
• Comfort working closely with product and OEM stakeholders on real-world tradeoffs.
• A build-first mentality. You want to solve hard engineering problems, not manage them from a distance.
• Basic English required; fluent English is a plus.
• Based in Kyiv or within daily commuting distance.

What You Get

• Work that matters: Build products that directly strengthen Ukraine’s defence capability.
• Top-of-market compensation plus equity.
• A senior technical role designed to keep you close to the code and end users
• Direct influence over the architecture and product that drives Occam autonomy into combat.
• We are able to discuss reservations for critical candidates with significant experience.

How We Work

We value speed, judgement and ownership. If you prefer clear boundaries, slow decisions and layers of approval, OCCAM is probably not for you. We want people who build, solve hard problems and adapt when reality changes — not people who wait to be told what to do.

Interview Process

• Typically four stages, completed within a few weeks.
• Offer conditional on a background check by security services.

We like hitting the enemy. You do too? Join us.

Full-Time | US Market | PST Working Hours
 

We are looking for an experienced Performance Marketing Manager to join a growing digital team focused on customer acquisition and lead generation in the US market.

This role is ideal for someone who combines strong paid acquisition expertise with a practical, hands-on approach. You will be responsible for launching, managing, and improving campaigns across several advertising channels while continuously looking for opportunities to increase lead volume and efficiency.

What You’ll Be Doing

• Manage customer acquisition campaigns across platforms such as Google, Meta, Microsoft Ads, Taboola, Nextdoor, and LinkedIn.
• Develop paid acquisition strategies for different services and target audiences.
• Manage the complete conversion journey — from campaign structure and targeting to landing pages, tracking, and lead generation.
• Analyze campaign performance and make data-driven decisions around budgets, creatives, audiences, and bidding.
• Run ongoing experiments with messaging, creatives, landing pages, and campaign structures.
• Identify opportunities to improve lead quality, conversion rates, and acquisition costs.
• Work with tracking and analytics tools to ensure accurate measurement and attribution.
• Use AI and automation solutions to improve research, campaign production, analysis, and reporting.

• Keep up with advertising platform changes and new acquisition opportunities.

   

What We’re Looking For

• Strong hands-on experience managing paid acquisition for US audiences.
• Previous experience generating leads for local/service-based businesses, ideally industries such as home improvement, HVAC, roofing, solar, remodeling, or similar.
• Proven ability to manage meaningful advertising budgets and generate leads consistently.
• Strong practical knowledge of Google Ads and Meta Ads; experience with additional acquisition channels is highly valuable.
• Understanding of the complete lead-generation lifecycle, including ads, landing pages, tracking, conversion optimization, and lead quality.
• Experience with Google Tag Manager, conversion tracking, analytics, and attribution.
• Strong English communication skills, both written and spoken.
• Comfortable using modern AI tools as part of everyday marketing workflows.

• Experience with CRM, marketing automation, or lead follow-up systems is an advantage.

   

What Makes Someone Successful in This Role

You’re someone who can take a business objective and turn it into an executable acquisition plan without needing constant direction.

You’re comfortable working independently, investigating performance issues, testing new approaches, and making decisions based on data.

You understand that successful performance marketing isn’t only about managing campaigns — it’s about understanding the entire path from the first click to a qualified lead.

You naturally look for ways to improve processes, automate repetitive work, and find new growth opportunities.

Working Style

We’re looking for someone who:

• Takes responsibility for outcomes rather than simply completing assigned tasks.
• Works quickly while maintaining attention to detail.
• Is comfortable questioning existing approaches when the data suggests a better direction.
• Enjoys experimentation and continuous optimization.
• Can operate autonomously in a small, performance-focused environment.

• Is interested in a stable, full-time, long-term position rather than combining multiple freelance projects.

   

Schedule

Full-Time

The position requires availability during PST working hours and regular collaboration with a US-focused team.

RedCore is an international business group that creates technological solutions for digital markets. Our products and services cover fintech, marketing, e-commerce, customer service, communications, and regulatory technologies.
