Jobs

About the Client:

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role:

We are looking for a Senior Software Engineer to design, build, and own significant components of the core query engine of a large-scale distributed data platform. You will lead work across query planning, optimization, and execution — driving architectural decisions, mentoring middle engineers, and pushing the platform's performance and scalability boundaries across all major clouds.

This is a systems-level, backend engineering role focused on distributed data processing internals — not application development or CRUD services.

Responsibilities:

• Architect, design, and implement significant components of the query engine — planner, optimizer, execution operators, memory management, and data access layers.
• Write and review high-quality, performance-critical code in Java and/or C++.
• Own end-to-end delivery of features from technical design through production rollout.
• Drive performance optimization work — profiling, benchmarking, and eliminating bottlenecks in latency- and throughput-sensitive paths.
• Integrate deeply with columnar formats, open table formats, and connectivity drivers.
• Mentor middle engineers, lead code reviews, and set technical standards for the team.
• Contribute to CI/CD architecture and quality processes across Jenkins, containerization, and multi-cloud deployment (GCP, AWS, Azure via Kubernetes / Docker).
• Debug complex, cross-layer issues spanning query planning, distributed execution, memory management, and I/O.
• Partner with US-based engineering leads on design reviews, architectural decisions, and roadmap execution.

Required Qualifications:

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Java or C++, with deep understanding of OOP, systems design, memory management, and concurrency. Candidates strong in both are especially valued.
• SQL & Data: Advanced SQL skills and strong understanding of query execution internals — planning, optimization, and operator implementation.
• Data processing systems experience: Demonstrated experience building or extending data processing systems — query engines, distributed databases, ETL/ELT frameworks, or analytical platforms.
• Engineering experience: 5+ years in backend/systems software engineering, with a track record of owning significant components.
• CI/CD & DevOps: Solid experience with Jenkins and modern engineering workflows.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes.
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and rigorous code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, leading technical designs, or owning components end-to-end.

Desired Skills:

• Deep experience with Apache Arrow (columnar in-memory format).
• Hands-on experience with Apache Calcite (SQL parsing, planning, optimization framework).
• Experience with Gandiva or LLVM-based expression compilation and code generation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Deep familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Deep understanding of query planning, optimization (cost-based, rule-based), and execution internals.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Track record of performance optimization at the systems level — profiling, vectorization, cache/memory-conscious design.
• Prior experience contributing to open-source data infrastructure projects.

Before applying, please make sure you have a portfolio to show us.

We run an internal data platform behind a talent representation intelligence product that maps out the entertianment industry.
 

We are rebuilding the platform (legacy Symfony/Angular → Django + React) because the current system stores its most valuable data as unstructured text and can't support where the product is going. . This is not a greenfield toy and not a rescue job — it's a planned rebuild with an unusual amount of groundwork already done:

• A product & architecture document with the domain model decided: what each module means, what dies, what changes, and the conventions (append-only history, structured-at-entry, derived-values-never-facts, and more)
• An epic breakdown with dependency order and explicit definitions of done
• A decisions register — every product ruling logged, searchable, current
• Approved feature specs for the major new modules (representation history, deals/endorsements restructure, awards, drafts)
• A migration standard: raw-row archives, legacy-ID mapping, conflict review queues, rehearsed cutover — nothing silently dropped, nothing silently merged
   

Your job is to design and build within that system: propose schemas and migration plans per module (we call these build contracts — you propose, product approves, then you build), stand up the foundation (auth, field-level permissions, API-first architecture), build the cross-cutting primitives (audit log, unified sources, soft delete, lookups), and run a phased legacy migration where reconciliation counts get reviewed, not just produced.
 

How we work — read this part twice:

• The documents are the spec; the legacy code is not. Many current features are unused and several database tables are mislabeled (we've mapped this). When you hit a question about what something should do, you ask — you don't resolve it from old code. We answer questions daily, in writing, fast.
• Gates are real. Every epic starts with your proposed schema + migration plan; implementation starts after approval. Epics close when their definition-of-done closes — including a researcher completing the workflow without your help — not when the tasks are checked off.
• AI tooling is welcome and expected. We assume you'll use agents/copilots — we do. What we hire for is what the tools can't do: judgment. You verify what your tools produce against the real schema and the real data before it reaches us. "The agent said so" is not a source. (Our favorite recent bug: a generated diagram claiming a name column was an integer. The person who catches that is who we're hiring.)
• Evidence over memory. Unknowns get investigated — code usage, row counts, what breaks — and then ruled on. We don't guess.
  
  You're a fit if:
• Senior Django + React, with real ownership of at least one system end-to-end (schema through UI through deployment)
• You've done at least one legacy migration or system replacement and can talk concretely about what went wrong and what you'd do differently
• You read before you build — genuinely. Our last mismatch was a capable developer who never opened the app or the documents; the interview is designed to detect this, so if it's not you, save us both the call
• You're comfortable proposing designs to a non-engineer product owner who is deeply involved, defending them in writing, and being overruled on product grounds without sulking
• Strong written English; async-first habits; you leave a paper trail by default
• Bonus, not required: search infrastructure (Typesense/similar), data-pipeline/ETL work, having worked alongside scraper/ingestion systems, PostgreSQL depth

We’re building a new product team and looking for the first key engineer to join the project.

This is not a role where you’ll simply contribute to an existing codebase. You’ll have real ownership over architecture, technical decisions, engineering standards, and the foundation of the product from day one.

The project is in the MilTech space, involving UAVs and telemetry systems.

What you’ll do

• Build a C++ system from scratch, from architecture to production
• Design scalable and maintainable software
• Work with multithreading, concurrency, performance, and memory management
• Make key technical and architectural decisions
• Help establish engineering processes, standards, and best practices
• Eventually contribute to building and shaping the engineering team

Requirements

• Strong Modern C++ (C++17/20) experience
• Solid understanding of:
  • Systems programming
  • Memory management, RAII, smart pointers
  • Multithreading and concurrency
• Strong STL knowledge: containers, algorithms, iterators
• Understanding of algorithmic complexity (O(1), O(log n), etc.)
• Strong OOP knowledge and SOLID principles
• Experience with architectural/design patterns
• Git, CMake, GCC/Clang
• Experience with linters and static code analysis
• Ability to work independently and take ownership of technical outcomes

Nice to have

You don't need experience with all of these. A strong C++ foundation and willingness to learn are more important.

• Networking: TCP/UDP, sockets, asynchronous I/O
• MAVLink: telemetry and command communication with UAVs/robotics
• GStreamer: video-stream processing, H.264/H.265 encoding/decoding, low-latency pipelines

Who we're looking for

Strong Middle or Senior engineer.

We're looking for someone who can operate independently, make technical decisions, and eventually help shape the engineering team.

❌ Not a fit: candidates with only superficial knowledge of C++, multithreading, or networking. We need hands-on engineering experience, not just exposure to these technologies.

What we offer

• Competitive market compensation
• Fully remote
• Official employment with mobilization reservation for eligible candidates in Ukraine, or cooperation via FOP
• Paid AI tools for development
• High level of technical ownership
• Opportunity to build a product and engineering team from the ground up

Fabula is a fast-growing D2C coffee brand in the United States. TikTok is our next major growth channel, and we're looking for someone to build and own it.

This role is responsible for our entire TikTok Shop growth engine - from affiliate recruitment and creator partnerships to content sourcing, campaign execution, and performance optimization.

You'll work directly with the founders to build a scalable creator ecosystem that drives measurable revenue, not just engagement.

This is not a traditional influencer marketing or social media management role. We're looking for someone who understands TikTok Shop as a performance channel and knows how to scale affiliate and creator programs that generate GMV.

What you'll own

• Build, manage, and scale our TikTok Shop Affiliate Program, including creator sourcing, vetting, onboarding, briefing, commission structures (Open Collaboration, Targeted, VIP), and ongoing relationship management
• High-volume creator and influencer outreach, gifting campaigns, negotiations, and partnership management
• Build and maintain a high-quality UGC pipeline, ensuring creators consistently produce content that can be repurposed for paid advertising (including Spark Ads and whitelisted content)
• Develop and execute our organic TikTok content strategy, including trends, posting cadence, creator collaborations, and community engagement
• Create FDA-compliant creator briefs and ensure all content aligns with platform and regulatory requirements
• Manage affiliate platform operations (Social Snowball, GRIN, Aspire, Modash, Insense, or similar)
• Analyze creator and affiliate performance using GMV, attributed orders, CAC, creator ROI, conversion rates, and other performance metrics
• Continuously test new outreach strategies, creator types, incentives, and partnership models to improve program performance

Success in this role is measured by GMV growth, creator activation rates, attributed revenue, creator ROI, CAC, affiliate retention, and the ability to build a predictable pipeline of high-performing creators.

You are

• 3–5+ years of experience managing TikTok creators, affiliates, or influencer programs for D2C/eCommerce brands or agencies
• You've personally built or managed a TikTok Shop affiliate program with measurable business results
• Experienced with TikTok Creator Marketplace and at least one affiliate platform such as Social Snowball, GRIN, Aspire, Modash, or Insense
• Comfortable managing high-volume outreach (50+ creator conversations per month) while tracking response rates and conversion through the funnel
• Strong written English - you write outreach messages, creator briefs, and partnership communications
• Performance-minded - you measure success in GMV, conversions, CAC, and creator ROI, not vanity metrics
• You use AI daily to improve outreach, creator research, briefing, content ideation, and operational efficiency. AI fluency is non-negotiable.
• Comfortable working closely with founders in a fast-paced environment and incorporating feedback quickly

• Highly organized and capable of managing multiple creator relationships simultaneously

   

Bonus:

• Experience with Spark Ads and whitelisted content workflows
• Existing creator network within supplements, wellness, health, beauty, or lifestyle niches

• Understanding of FTC and FDA compliance requirements for influencer marketing

   

Schedule

• Fully remote
• Minimum 6-hour overlap with US Eastern Time (10:00 AM–4:00 PM ET)

About us

We are Folqs, a fast-growing D2C supplement brand in the United States (colostrum + beef organs). We're scaling fast - paid media, advertorials, landing pages, full funnels - and have built everything in-house. 

We're looking for someone to own our entire performance creative system - from research and messaging to creative production, testing, and scaling winners across Meta, Google, TikTok, and advertorial funnels.

You'll have significant ownership over our creative strategy and will work directly with the founders to shape the direction of our customer acquisition efforts.

This is not a branding, social media, or content marketing role. We're looking for someone who has built and scaled direct-response paid acquisition creatives for D2C/eCommerce brands and is obsessed with performance.
 

What you'll own

• Creative strategy across all platforms: Meta, Google, advertorials, TikTok paid (Spark Ads + whitelisted creator content)
• Full funnels: landing pages, advertorials, VSLs, email sequences
• Research angles hooks: customer reviews, surveys, Reddit, competitor ad libraries
• Creative briefs for editors, UGC creators, and designers
• Scripting + copy oversight: you write or heavily edit scripts, headlines, and page copy
• Daily performance reads on hook rate, ROAS, thumbstop rate, CTR, creative fatigue, and other key metrics - you decide what to kill, scale, and iterate
• Production pipeline: sourcing UGC creators, managing editors, and ensuring a consistent pipeline of fresh creative assets ready for testing
• Structured testing frameworks - one variable at a time
   

Success in this role is measured by improvements in ROAS, CPA, hook rate, CTR, creative win rate, and the speed and quality of creative testing and iteration.
 

You are

• 4–6+ years of experience creating performance creatives for D2C/eCommerce brands or eCommerce agencies (not B2B, not a generalist)
• Deep direct-response background - you understand customer psychology, hooks, messaging frameworks, and how to turn insights into high-converting creatives
• Fluent in Meta and at least one of the following: Google, TikTok Paid, or advertorial syndication (Outbrain/Taboola)
• You've owned a creative pipeline end-to-end - from research and strategy through production, launch, and performance analysis
• Strong written English - you write or heavily edit creative briefs, scripts, headlines, and landing page copy
• A hands-on operator. Not a deck-maker. Not a strategist who hands ideas off to someone else to execute.
• You use AI daily to accelerate research, messaging, scripting, creative ideation, and operational workflows. AI fluency is non-negotiable.
• Comfortable working closely with founders in a fast-paced environment and incorporating feedback quickly
• Experience collaborating with video editors, designers, and UGC creators to bring winning concepts to life
• Bonus: Experience with creative analytics and research tools such as Motion, Foreplay, Meta Ads Library, Triple Whale, Northbeam, or similar platforms
• Bonus: Understanding of FTC compliance
   

Schedule

• Fully remote
• Minimum 6-hour overlap with US Eastern Time (10:00 AM–4:00 PM ET)

We're an early-stage start-up working at the intersection of legaltech and fintech. We're looking for a senior engineer to be our first hire, working directly alongside our CTO to build the product from the ground up. This is a high-ownership role, and cap-table access is on the table for the right candidate.

You build systems where correctness under failure isn't optional — it's the product.

• Rigorous about failure paths. Idempotency is muscle memory (outbox pattern, stable IDs), and you reach for explicit state machines on payments, approvals, and sagas.
• Security-first mindset. You keep security in mind across the stack and recognise where extra caution is needed.
• Comfortable across a backend tech stack. Our main components are Go, PostgreSQL, gRPC, and FreeBSD, but we will also have components in Java and Python, so you must be comfortable across multiple domains. A little frontend work in TypeScript/React can also happen
• Strong in AI-driven development. You have a considered view on your toolset — when to trust the model and when not to — and how to build repeatable workflows.
• Structured enough to own the operational side — writing and following deployment runbooks and DR drills, and treating "we can do an almost-automatic failover at 03:00 without improvising" as a real requirement.

As a profile you will have experience working in Payments, Web3 or other FinTech domains where accurancy, consistency and security is of high importance.

You are comfortable working independent, but reporting to a team structure.

You own your issues, your code and your PRs, You are comfortable taking decisions but also open to discuss when you feel it is needed.

Location & ways of working

Working mode is fully remote. We'd prefer a base in a timezone between UTC−4 and UTC+6, and you should be happy to join in-person events likely in Denmark every 2-3months.

• Experience building or using marketing automations with AI and no-code/low-code tools to improve operational efficiency.
