Who are we searching for?

We're looking for an Enterprise Finance Engineer — someone who can design and implement AI-powered finance systems for our largest and most complex customers. This role sits at the intersection of Finance, Accounting, Systems, Automation, Integrations, and AI.

You'll work directly with CFOs, Finance Directors, Controllers, IT teams, and finance teams to redesign finance operations through AI, automation, and system integrations. You'll own a small number of large, strategic customers end-to-end — from understanding business processes to designing scalable solutions and continuously improving them as the business evolves.

This isn't a role for someone who wants repeatable implementations or well-defined requirements. Every customer is different. You'll navigate ambiguity, work with demanding stakeholders, and solve unique technical problems without predefined playbooks. If that energizes you, we'd love to meet you.

What are your responsibilities?

• Design and implement AI-powered finance systems for enterprise customers
• Lead discovery sessions to understand finance processes and identify automation opportunities
• Build workflows for reporting, forecasting, financial controls, reconciliations, and planning
• Design integrations across ERP, accounting, CRM, payment, BI, and data platforms
• Translate finance requirements into scalable workflows, automations, and system architecture
• Build AI agents, validation logic, and automation frameworks that reduce manual work
• Partner with Engineering on APIs, integrations, and workflow orchestration
• Coordinate across Engineering, Product, and Customer Success as the trusted technical partner for your customers
• Continuously improve customer solutions as business needs evolve

What are the preferred requirements for the role?

• 10+ years implementing finance systems, automations, or enterprise finance operations
• 1+ year building AI-powered automations, agents, workflows, or internal AI tools
• Hands-on experience with APIs, system integrations, automation platforms, and data warehouses
• Experience working with enterprise or multi-entity organizations (multiple stakeholders, legacy systems, changing requirements, long implementation cycles)
• Proven experience leading implementation projects end-to-end — discovery, solution design, rollout, training, and support
• Fluent English
• Strong understanding of finance and accounting processes, including financial close, reporting, FP&A, revenue, AP/AR, and financial controls
• Ability to understand how financial data flows across systems and departments
• Experience with ERP, accounting, or billing systems
• Proven impact in numbers: hours saved, manual work reduced, faster reporting, or fewer errors
• Excellent communication skills and experience working directly with senior finance stakeholders
• Strong systems thinking — the ability to see the bigger picture and break complex finance processes into scalable, maintainable, reusable solutions
• Ownership: taking full responsibility from problem discovery through implementation and post-launch optimization
• Learning agility: quickly mastering new AI tools, technologies, and approaches
• Strong problem-solving under ambiguity, with the judgment to make trade-offs and prioritize
• Strong drive to eliminate repetitive manual work
• Proactivity and a high level of responsibility
• Ability to work in a fast-paced environment

Will be a plus:

• Python or other scripting experience
• SQL and the ability to retrieve and validate financial data independently
• Experience with tools like NetSuite, QuickBooks, Xero, Stripe, Salesforce, HubSpot, Zuora, BigQuery, Snowflake, PostgreSQL, Looker, Power BI, Tableau, Zapier, Make, n8n, or Workato
• Understanding of enterprise architecture — security, scalability, governance, and integration patterns
• Experience working with US-based clients or startups

Reporting Structure: reporting to the Head of FP&A

Recruitment Process:

• Soft skills interview with the recruiter
• Test task
• Hard skills interview with the Head of FP&A
• Culture fit interview with the Head of FP&A/VP of Operations

Why work with us?

• Build the future of finance work — design AI-native finance operations, not just maintain them
• Rapid skills improvement (you'll work with multiple client businesses with different models and challenges)
• Growth opportunities according to our seniority grading (it comes with a compensation increase)
• Flexible schedule and time-off policy
• 18 days of paid vacation per year, paid sick leaves

We are seeking a Technical Designer with strong ownership mindset to take end-to-end responsibility for making combat — especially gunplay, but also boss fights and enemy behaviors — look stunning, feel incredibly satisfying, and deliver that "juicy" third-person shooter polish (especially when it comes to gunplay). They will own the full pipeline: prototyping, implementing, tuning, integrating feedback layers, identifying and resolving asset gaps (e.g., missing animations, VFX, or sounds), and driving cross-team alignment until the combat feels perfect in-game. This is Blueprints-heavy work in UE5 with a focus on rapid iteration and subjective feel, not deep engine-level C++ programming.
 

Key Responsibilities:

• Take full end-to-end ownership of combat polish features (boss fights, enemy behaviors, hit feedback, etc.)
• Prototype and implement responsive combat mechanics and boss/enemy behaviors using Unreal Engine 5 (primarily Blueprints, data-driven systems)
• Own the "feel-good" tuning loop: hit reactions, impact feedback, recoil, aim/momentum preservation, input buffering, procedural elements — iterating until it feels snappy, weighty, and rewarding
• Set up and refine combat animation systems (Montages, Blend Spaces, notifies, Control Rig basics, IK) — and if animations are missing or need tweaks, proactively align with animators to define requirements, provide feedback, and integrate updates
• Layer juicy visual/audio feedback: hit-stop, camera shakes, Niagara particles, synced sound cues — and if VFX or sounds are incomplete/mismatched, drive alignment with VFX artists and sound designers to spec, iterate, and ensure perfect sync
• Design and implement boss fight patterns/phases (telegraphs, vulnerability windows, minion spawning, state transitions) with strong emphasis on readability, pacing, satisfaction, and end-to-end execution
• Rapidly iterate via playtesting: identify feel issues, adjust timings/values/effects, and own the fixes until combat passes subjective polish benchmarks
• Create/support simple tools or data setups (data tables for behaviors/stats) to enable efficient tuning and future-proofing
• Collaborate cross-discipline as the combat owner: work closely with animators, VFX artists, sound designers (and programmers when needed) to fill gaps, provide clear direction/feedback, and ensure assets integrate seamlessly for the best possible player feel
• Ensure combat polish holds up in multiplayer contexts (extraction, battle royale, team modes)
   

Requirements:

• 4+ years professional experience as a Technical Designer, Combat Designer, or similar in Unreal Engine projects (UE4/UE5 strongly preferred)
• Proven portfolio/reel demonstrating end-to-end combat ownership: examples of juicing hits, polishing boss fights, or third-person action feel — showing before/after passes, asset integration, and cross-team collaboration results
• Strong UE5 hands-on skills: Blueprints mastery, animation integration, Niagara/particle systems, camera tools, behavior trees/EQS for enemy logic
• Demonstrated ownership mindset: you take features from concept to final polish, proactively spotting/fixing gaps (e.g., "this hit needs better VFX — let's align with the artist") rather than handing off prematurely
• Deep passion for game feel — you can diagnose why combat feels "off" and drive iterations (including cross-team) to make it exceptional
• Experience in third-person shooters/action games — bonus for boss fight polish and end-to-end delivery
• Excellent collaboration and communication: you thrive on aligning specialists (animators, VFX, sound, gameplay programmers) with clear specs, feedback, and follow-through
• Ability to own rapid playtest → iteration cycles independently
   

Nice-to-Haves:

• Shipped titles with standout combat feedback (indie/AA/AAA)
• Experience leading boss phase balancing and polish passes
• Light C++ exposure for reading/modifying existing code
