We are looking for a Senior Security Engineer with deep, hands-on Active Directory expertise to secure and harden enterprise identity infrastructure. You will own AD architecture, hybrid identity, and PKI across forests and domains, with a strong focus on security hardening and reducing attack surface. This is a senior, independent role — you should be comfortable owning identity security end-to-end with minimal ramp-up.

Details
Work setup: Remote/hybrid, with paid onsite visits to Baltic offices approximately once per month for 2–3 days
Location: Europe, strong preference for the Baltics
Duration: Long-term
Type of collaboration: Full-time employment
English: Upper-intermediate / fluent

About the role
You will be responsible for the design, hardening, and ongoing security of Active Directory environments — spanning forest and domain architecture, DNS, Group Policy, and replication. A core part of the role is reducing the identity attack surface: applying security hardening best practices, managing Kerberos configuration, and running Active Directory Certificate Services (PKI) securely. You will also work across hybrid identity, connecting on-prem AD with Microsoft Entra ID and ADFS, ensuring consistent security posture across both environments.

You have
Strong, hands-on experience with Active Directory architecture — forests, domains, trusts, and multi-domain environments
Deep knowledge of Windows Server, DNS, Group Policy, and AD replication
Proven experience with security hardening of AD environments and Kerberos
Hands-on experience with PKI and Active Directory Certificate Services (AD CS)
Experience with Microsoft Entra ID, hybrid identity, and ADFS
Upper-intermediate or fluent English

What to do
Design and maintain secure Active Directory forest and domain architecture
Harden AD environments against common attack paths (Kerberoasting, golden/silver ticket, DCSync, etc.)
Manage DNS, Group Policy, and AD replication across the environment
Administer and secure PKI infrastructure via Active Directory Certificate Services
Own hybrid identity integration between on-prem AD, Microsoft Entra ID, and ADFS
Audit and remediate security gaps across identity infrastructure

About the company

Turning marketing into a market-domination weapon, we created a new category - the marketplace for future customers. Businesses shop for leads as they shop for products in e-commerce: you see everything about a lead before you buy - full transparency, control, and predictable outcomes. We're the #1 lead marketplace in the USA, and we're accelerating.

Role overview

We are looking for a Product Manager to ensure we always build the most valuable things for our marketplace — measured in money, not opinion. You will own the outward half of the product: users, market, and the "what and why." Working closely with a Product Owner who owns delivery ("how and when"), your job is to make sure not a single sprint is spent on something that does not move LTV, margin, or retention.

Requirements

3+ years in B2B SaaS or marketplaces, with clear examples of metrics you moved and can prove.

Strong understanding of unit economics, including LTV, CAC, payback, and contribution margin.

Hands-on user research experience with real synthesis work behind it.

Ability to tie product ideas to measurable upside before development starts.

Experience pulling and working with your own data using SQL, Amplitude, BigQuery, or similar tools.

English C1+; your users are American real estate investors, and communication needs to be sharp and clear.

AI-first by default — if you are not using AI to 3x your output already, you will be behind our engineers.

High ownership and strong decision-making in ambiguous, fast-moving environments.

What You'll Be Doing

Talk to users constantly: buyers, power accounts, and churned users — and turn conversations into decisions, not decks.

Own platform improvement broadly across onboarding, buying experience, lead quality, retention, and monetization. Find the weakest link, fix it, then move to the next.

Own the unit economics of every bet by tying each brief to LTV, CAC payback, margin per lead, or revenue per active user. If you cannot put a number on the upside, it is not a brief yet.

Model value before anything is built, using rough sizing of expected impact so engineering time goes to things that move money, not things that only feel nice.

Write one-page briefs built around problem, evidence, and expected impact, then hand them off and trust the execution.

Ship experiments weekly, kill failures fast, and scale winners.

Pull your own data directly; there should be no analyst between you and the truth.

Track competitor changes closely and know what they shipped before users tell you.

This is not for you if

You measure success in features shipped.

You cannot tie a feature to a number.

You want to manage the sprint and own the delivery. That is a different role.

What we expect from you (first 3 months)

We do not do long onboarding. Access on day one, context in days, a real problem in week one. We hire people who create value with incomplete information, because that is the job every day after probation too.

End of month 1: you know the platform as a real user does because you have used it like one; you have mapped the weakest points in the funnel, ranked with evidence and value; and you have handed off your first accepted brief.

End of month 3 (the bar): multiple shipped changes with measurable results you can defend, with at least one of them moving a core metric such as activation, churn, LQS, or revenue per user. A live experiment pipeline exists so something is always being tested. Your validated brief backlog is deep enough that the team never waits on you for direction. We trust your "this is worth building" without re-checking it.

How We Work With You: We use honest checkpoints at 2 weeks, 1 month, and 2 months. We judge trajectory, not perfection. Wrong fast and corrected beats slow and safe. If the fit is wrong, both sides should know by month 2 and say it out loud.

Nice to Have

Experience in startup or fast-scaling tech environments.

Experience in marketplace, SaaS, real estate, lead generation, or other performance-driven digital businesses.

Familiarity with experimentation systems, product analytics, and growth-focused product work.

What We Offer

Impact: Work at the core of a product-led, AI-powered startup where your decisions directly affect business performance.

Autonomy: High ownership, low bureaucracy, and real authority over product direction.

Flexibility: Remote-first culture with flexible hours and async-friendly communication.

Compensation: Competitive salary above the market average.

Team: Join a smart, passionate team that moves fast, supports each other, and builds cool stuff.

Time Off: Three weeks paid vacation plus 5 paid sick days annually.

Growth: Unlimited learning policy — paid courses, books, and growth resources.

AI-Heavy Environment: AI is deeply embedded across prospecting, research, and workflows.

Ownership: Real decision-making power and direct ownership of your outcomes.

We're looking for a Middle+ Data/Databricks Engineer to join our data team and take ownership of pipelines built on Databricks. You'll design and run production-grade ETL/ELT workloads, work with the lakehouse (Delta Lake) architecture, and partner closely with analysts, data scientists, and business stakeholders who rely on the data you deliver. "Middle+" here means roughly 3–5 years of hands-on data engineering experience: you can own a pipeline end to end with minimal supervision, make sound design decisions, and are starting to mentor more junior engineers — without yet carrying full architectural ownership of the platform.

• Working knowledge of Git and CI/CD practices for data engineering.
• Understanding of data governance, access control, and security basics (Unity Catalog is a plus).
• Good written and spoken English; Czech or Slovak is a plus but not required.

• Experience with dbt for transformation and testing.
• Solid Python software-engineering practices — testing, packaging, typing.
• Infrastructure-as-code experience (Terraform).
• Exposure to MLOps or ML pipeline support.
• Experience in a regulated or large enterprise data environment.

What We Offer

• Fully remote work with flexible hours, based anywhere in the Czech Republic.

• A modern, actively evolving data stack rather than legacy maintenance work.
• Direct collaboration with senior engineers and architects — real input on design decisions.
• Budget for training, certifications, and conference attendance.
• A flat structure with fast decision-making and minimal bureaucracy.
