Founded in 2009, Chern & Co is a corporate services company helping international entrepreneurs and businesses establish and manage their companies in Ireland.

We support startups, SMEs, and e-commerce businesses with company formation, tax registration, accounting, and ongoing corporate compliance. Our role is to make the administrative and regulatory side of running a business clearer and easier for our clients, allowing them to focus on growing their businesses.

With an established presence in Ireland and plans to expand into the UK, we continue to develop our services and support businesses operating across borders.
 

🚀 About the Role

We're looking for a Documentation & Case Processing Specialist (Company Formation) to help ensure that company registration and related administrative processes run smoothly from start to finish.

You'll work primarily behind the scenes, handling client documents, preparing applications, coordinating submissions, and keeping each case organised and on track. You'll also communicate with clients when needed to collect missing information, clarify details, and keep the process moving.

This is a detail-oriented role where accuracy, consistency, and following procedures really matter. You'll be working with official documents, sensitive information, and multiple cases at different stages, so staying organised and keeping track of deadlines will be essential.

You don't need prior experience with Irish company formation — we'll provide training on the relevant procedures. What matters most is your existing experience working with documents, your ability to learn quickly, and your willingness to take ownership of your work.
 

📋 Key Responsibilities

✅ Company Formation & Documentation: Prepare and process documents, applications, and official forms required for company registration, tax registration, and ongoing corporate compliance in Ireland. Ensure all paperwork is accurate, complete, and submitted on time.

✅ Client Communication & Support: Communicate with clients via email and messaging platforms to collect documents, clarify information, provide updates, and coordinate registration processes. Respond to requests and help resolve issues when needed.

✅ Case & Service Coordination: Manage client cases from document collection to service completion, track deadlines, send reminders, and coordinate with government offices, banks, external specialists, and service providers to ensure everything runs smoothly.

✅ CRM & Reporting: Maintain accurate client records in Bitrix24, update case statuses, tasks, deadlines, and documentation. Prepare regular reports for the Supervisor and COO and work towards agreed performance KPIs.

✅ Quality Control & Process Improvement: Check documents and completed work for accuracy and compliance, monitor the quality and timeliness of external providers, identify process improvements, and help maintain internal procedures and service standards.

✅ Additional Support: Assist with client proposals and relevant service recommendations, support sales and marketing initiatives, and participate in industry events when needed.
 

💻 What We're Looking For

🔹 2+ years of relevant experience in documentation, administration, case processing, client onboarding, legal or accounting support, banking, compliance, or a similar field.

🔹 Hands-on experience with documents: You know how to prepare, review, and process paperwork carefully, and you understand why small details matter.

🔹 Strong organisational skills: You'll manage several cases, deadlines, and follow-ups at once. You can prioritise tasks, keep track of outstanding items, and make sure nothing gets overlooked.

🔹 English C1, particularly strong written communication skills for client correspondence and documentation.

🔹 Experience with CRM systems, databases, or case-management tools. Bitrix24 experience is a plus.

🔹 Ability to learn quickly: There will be plenty of new information, procedures, and details to absorb, especially at the beginning. You don't need to know everything from day one, but you should be comfortable learning and applying new information.

🔹 Responsibility and independence: You can follow established procedures, handle routine tasks consistently, and take ownership of your work without constant supervision.

🔹 Discretion and reliability: You understand the importance of handling confidential client and financial information responsibly.
 

🌟 It Would Be a Plus If You Have

🔸 Experience in corporate services or company formation.

🔸 Knowledge of KYC/KYB, AML, tax registration, or corporate compliance.

🔸 Experience with government portals, company registries, or official filing systems.

🔸 A background in banking, insurance, or immigration services.
 

🎁 What We Offer

💶 Salary: €1,100–€1,300 gross/month, potentially higher for directly relevant experience.

💰 Quarterly performance bonus linked to additional-service sales.

🏡 Full-time, fully remote position (independent contractor agreement).

🌴 20 paid vacation days, increasing to 30 after one year (pay structure to be discussed).

📚 Professional development budget of up to €500/year after six months.

🎓 Full onboarding, professional training, and mentorship.

🌍 Long-term opportunity in an international company.
 

💌 Interested in Joining Us?

Does this sound like the kind of role you'd enjoy? If you're organised, responsible, and ready to learn, we'd be happy to hear from you.
 

About Us:

We are a growing B2B tech agency. We already have a high-level Lead Gen Strategist building our outreach "Playbook." Now, we need a smart, autonomous, and detail-oriented Lead Generation Specialist to execute it.

The Role:

You will be the "hands" on the keyboard. We will provide the strategy, the target audience, and the messaging frameworks. Your job is to research the right prospects, personalize the outreach, send the messages on LinkedIn and Upwork, and manage the inbox to book meetings.

Your Responsibilities:

•   Prospecting: Find decision-makers (CEOs, CTOs, Founders) that fit our exact Ideal Customer Profile.
•   Personalization: Write highly customized first lines/icebreakers based on their profile or company news. (No lazy copy-pasting)
•   Execution: Send proposals on Upwork and manage LinkedIn outreach campaigns.
•   Inbox Management: Reply to interested prospects promptly and get them to book a call.
•   Tracking: Log your daily numbers (messages sent, replies, calls booked) in our tracker.

Requirements:

•   Excellent written English (you must sound like a native professional).
•   Highly autonomous. You don't need someone watching your screen to get the work done.
•   Experience with LinkedIn Sales Navigator and Upwork.
•   High attention to detail.

Compensation:

We offer a reliable hourly rate PLUS a performance bonus for every Qualified Call you book. If you are good at this, you will make great money.

How to Apply (CRITICAL):

To prove you have good English and attention to detail, you MUST include a link to a 1-minute Loom video or audio recording introducing yourself.
 

Also, answer this question in your proposal: If you are reaching out to the CTO of a software company, what is one thing you would look for on their LinkedIn profile to write a personalized first sentence?

(Proposals without a video/audio link will be automatically declined).

We are looking for a highly intelligent and strategic Product Owner to join Out Of The Box Systems and take ownership of new and early-stage products within our company.

Your objective is to take ideas from concept to market-ready products and ultimately help turn them into profitable businesses.

This is not a traditional Product Owner role focused only on backlog management. The role is heavily focused on Marketing, UX Design, Fundraising, and High-Level Strategy. You will identify opportunities, shape product strategy, find paths to revenue, and execute go-to-market plans.
 

Who are we?

We are Out Of The Box Systems: a Ukrainian team of passionate, battle-tested engineers and creators united by one goal — delivering real results with clarity, precision, and autonomy.

We specialize in challenging engineering projects, including Rust Development, AI Engineering, Computer Graphics, Automation, and Custom Software Development. We value ownership, accountability, continuous learning, and practical problem-solving over bureaucracy and unnecessary processes.

Our team works remotely with clients from the USA, Canada, Europe, and other international markets.
 

Workload

• Full-time remote collaboration
• Long-term role within our company
• Direct collaboration with company leadership and engineering teams
• High level of autonomy and ownership
• Focus on measurable business results
   

What You Will Do

• Fundraising & Capital Strategy: Research, strategize, and pursue grant funding and other non-dilutive financing opportunities. You should know how to position and pitch a product to win capital.
• UX & Product Design: You don’t just sell the product — you shape it. Design intuitive user flows, build wireframes, and make sure the product experience is frictionless before development.
• Marketing & Go-To-Market: Build the marketing engine from scratch. Validate ideas, identify target markets, find early adopters, and create a path toward actual revenue.
• Strategize & Advise: You will not wait for instructions. Analyze the market, advise company leadership on the best strategic moves, and build the roadmap to execute them.
• Solve Complex Problems: Use AI, technology, resourcefulness, and first-principles thinking to bypass bottlenecks and move significantly faster than a traditional Product Owner.
   

Who You Are

• 100% Dedicated Full-Time: This is not a side hustle. This role should be your primary professional focus.
• Extremely Fast Learner: You can quickly understand new markets, funding landscapes, business models, and tools.
• A Scrappy Marketer & UX Thinker: You know how to get attention, validate ideas, and design user experiences without a massive budget or a dedicated design team.
• Strategic & Proactive: You don’t need detailed instructions to move forward and are comfortable challenging assumptions.
• Loyal & Ambitious: You want long-term collaboration where your financial upside is directly tied to the success of the products you help build.
• Upper-Intermediate English (B2) or higher
   

Compensation — Skin in the Game

We reward results and profitable outcomes, not simply time spent at a desk.

• Base: $500–$1,000/month
• Performance Bonuses: milestone bonuses and revenue-sharing tied to funding, launch, customer acquisition, and profitability
• Initial OTE: approximately $1,500–$2,000+ per month
• Uncapped Upside: if the products launch successfully and scale, earning significantly more — potentially $10,000+ per month — is possible
   

If you are looking only for a safe, guaranteed high salary without being directly accountable for results, this role is probably not the right fit.
 

What You Get

• Ownership of new and early-stage products within the company
• Direct collaboration with company leadership and engineering teams
• Significant influence over product and business strategy
• Performance-based financial upside
• Flexible remote work environment
• Long-term collaboration
• 2-year B2B contract reflecting our long-term commitment to every team member

The role

We are not filling a headcount slot. We want the person to own the trading systems side of a young market data and trading infrastructure business, with the door open to becoming a partner.

We are building a Rust market data and trading infrastructure platform. Several venues are already live in the capture pipeline, across CEXs, DEXs and prediction markets, and expanding that coverage is the bulk of the near-term work. Full-depth order books and trades, normalised so one integration serves many venues, on columnar storage with an analytical query layer over it.
 

What you would own

Venue connectivity end to end, from feed through normalisation, gap detection and replay. The shared abstraction every venue fits behind, which will either hold or turn into a special case per venue. Correctness of the capture path, including the boring parts that decide whether a backtest is trustworthy. Execution components as they come online. Read-side today, but it is on the path. Operability, since nobody hands off support to another team here. Technical direction in your area. You argue the trade-off, you make the call, you live with it.
 

Who we are looking for

We're looking for someone with a deep interest in trading and market dynamics. Proficiency in Rust, especially async and Tokio, is essential, and so is a solid grasp of multithreading and concurrency. Hands-on experience with market data or trading systems, such as exchange feeds, order books and exchange APIs, counts for a lot. You should be able to critically evaluate code changes and anticipate their long-term impact. Break down your own work into actionable tasks and prioritise them effectively. Experience with exchanges, market making, order execution, time-series storage such as ClickHouse or Parquet, or AWS/Linux performance work is a plus.

Languages: Ukrainian – upper-intermediate (B2+) spoken; English – B2, confident with written communication and technical documentation.
 

Seniority and time

We are not labelling this junior or senior. What matters is whether you can carry a component without much direction. Learning the trading domain here is fine.

The first three months are a full-time probation period. After that we can talk about a partnership and other ways of working together, part-time included.

How we hire

1. A logical reasoning test, around 40 minutes. Abstract pattern matching, no coding.
2. A bug fix. You get a small exercise repository with a bug ticket and a pull request that tries to fix it. Review it as you would a teammate's, and if its fix falls short, write your own. You have 72 hours from the moment you accept the invitation.
3. If your bug fix holds up, a 45-minute call. We get to know each other first, and then go through your review and your fix together.
    

What we can offer

You would build the thing rather than maintain someone else's version of it. Venue connectivity, capture guarantees, ordering and state under failure, and execution once the read side is solid. Not many engineers get to work on a system like this, and the experience is hard to acquire any other way.

The data comes with it. Full depth across every venue we capture, yours to research against. Buying comparable history costs real money, and most engineers who want to test an idea properly never get near it.

Pay is $1,000 a month, for the three-month probation only. That is the real figure, not a placeholder. We know it is well below what an experienced Rust engineer earns elsewhere, and we would rather say so here than have you find out at the end of the process. After probation, a partnership may follow for the right person, with a share of the revenue once there is any, and pay from then on is part of that conversation.
 

How to apply

Please attach your CV and put your GitHub username in your cover letter (for example, GitHub: octocat). We read the CV to see your experience, and use the username to send you the bug-fix task.

About Our 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 work on the core query engine of a large-scale distributed data platform. You will own significant components across query planning, optimization, and execution — both driving improvements and acting as a trusted owner of production quality: diagnosing complex customer-reported issues and delivering safe, well-tested fixes across supported release lines. Engineers with staff-level scope and ambitions are very welcome.

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 query engine components — planner, optimizer, execution operators, memory management, and data access layers
• Diagnose and resolve complex production and customer-reported issues across the full query path — correctness, performance, memory, concurrency, resiliency, and compatibility
• Develop, review, and backport fixes across multiple supported release lines; strengthen regression prevention
• Write and review high-quality, performance-critical code in Java and/or C++
• Analyze query profiles, execution plans, logs, and telemetry to drive performance optimization — profiling, benchmarking, and eliminating bottlenecks in latency- and throughput-sensitive paths
• Integrate with columnar formats, open table formats, and connectivity drivers
• Improve regression tests, diagnostics, and observability; contribute to CI/CD architecture and quality processes in Jenkins
• Mentor middle engineers, lead code reviews, and help set technical standards
• Debug complex cross-layer issues spanning query planning, distributed execution, memory management, and I/O, partnering with US-based engineering leads

Required Qualifications

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field
• 5+ years in backend / systems software engineering with a track record of owning significant components end-to-end
• Strong proficiency in Java or C++ (comfort with both is especially valued), with deep understanding of OOP, systems design, memory management, concurrency, and asynchronous programming
• Advanced SQL and solid understanding of query execution internals — planning, optimization, operator implementation
• Experience building or extending data processing systems: query engines, distributed databases, ETL/ELT, or analytical platforms
• Ability to assess change risk in a mature production system; experience supporting software across multiple versions, branches, or customer environments
• Hands-on experience with Jenkins and modern CI/CD workflows; Docker and Kubernetes
• Hands-on experience with at least one major cloud (GCP, AWS, or Azure)
• Confident Git/GitHub workflows and rigorous code-review habits
• Comfortable with AI-assisted development workflows — using modern AI tools for code comprehension, debugging, and test generation, and critically validating their output
• Prior experience mentoring engineers, leading technical designs, or owning components end-to-end
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

Desired Skills

• Apache Arrow (columnar in-memory format) and SQL planner/optimizer frameworks such as Apache Calcite
• LLVM-based runtime expression compilation / code generation
• Open table formats — Apache Iceberg, Delta Lake, or Hudi — and columnar file formats such as Parquet, Avro, or ORC
• MPP query engines (Presto, Trino, or similar); background with distributed data platforms such as Spark, Snowflake, or Databricks
• Deep understanding of query optimization (cost-based, rule-based), vectorized execution, memory management, spilling, and caching
• Connectivity drivers: JDBC, ODBC, Arrow Flight
• Managed Kubernetes (GKE/EKS/AKS) and multi-cloud exposure; Terraform; cloud object storage (AWS S3, Azure Data Lake Storage, Google Cloud Storage)
• SaaS operations experience: incident response, profiling, observability, release and backport processes
• Systems-level performance work and open-source contributions to data infrastructure projects

Details

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team
