Our client is  looking for a talented and hands-on Game UI & Multimedia Designer to join our team working on a mobile-first realistic shooter built in Unreal Engine 5.

The main focus of this role is creating high-quality, visually impressive UI for a modern realistic shooter. You will design everything from HUDs and gameplay interfaces to menus, inventories, loadouts, matchmaking, mission screens and progression systems.

You will work closely with our game designers and Unreal developers, who will bring your designs into the game. You should therefore have a good understanding of Unreal Engine 5 and UMG, but this is primarily a visual design role — we are looking for someone whose strongest skill is creating exceptional game UI, rather than programming or technical implementation.

Alongside game UI, you will also create gameplay clips, trailers, motion graphics and promotional content using footage captured from the game.

What we are looking for

• Strong professional experience in game UI design, ideally for shooters, action games or realistic games
• A strong portfolio showing polished, modern HUDs and in-game UI
• Excellent understanding of the visual language used in realistic and military-style games
• Ability to design complete game interfaces, including HUDs, menus, inventories, loadouts, mission screens, progression systems and other gameplay UI
• Strong UI/UX fundamentals, combining visual quality with readability and gameplay usability
• Good understanding of Unreal Engine 5 and UMG, with the ability to prepare designs and assets for efficient implementation by our Unreal team
• Strong knowledge of Photoshop, Illustrator, Figma, After Effects, Premiere or equivalent tools
• Ability to create animated UI, motion graphics and UI transitions
• Ability to capture and edit compelling gameplay footage, gameplay clips and trailers
• Good understanding of cinematic editing, pacing, sound and presentation for game marketing content
• Comfortable using AI tools for ideation, design exploration and content creation
• Strong visual eye and exceptional attention to detail
• Highly organized and systematic when managing source files, assets, versions and deliverables

Most important

We are looking for someone who can take a gameplay requirement, concept or rough wireframe and transform it into a visually outstanding, production-ready game UI.

Your portfolio should show UI that could belong in a high-quality modern shooter. We are not primarily looking for candidates whose experience is focused on websites, mobile apps or corporate interfaces.

Overview

We are looking for a Senior Engineer to take primary ownership of its Go-based Virtual Signer and help maintain shared signing SDKs and integrations across server and mobile platforms.
 

The Virtual Signer participates in MPC and threshold signing alongside mobile devices. This is an opportunity to take ownership of a security-critical component, strengthen its production reliability, and contribute to future transaction approval and post-quantum signature capabilities.

About the Environment:
The Go-based Virtual Signer orchestrates signing between server and mobile participants. It integrates with MPC and threshold-signature libraries, supports encrypted storage and must recover safely from interrupted signing sessions and other failures.

The component has been rebuilt over roughly the past year and is around MVP stage. It is working, with outstanding pull requests, logging and visibility improvements, and race conditions to address. The incoming engineer may have limited handover from the previous maintainer.

The engineer will work with backend and mobile engineers, testing support and a cryptographer who also maintains the repository. Collaboration across UK and Eastern Canada working hours will be important.

The environment includes Go, Linux and Docker, with shared SDKs and bindings for Swift, Kotlin and JavaScript/TypeScript. Jira, Slack, GitHub and Google Workspace are used for collaboration.

The initial focus is a robust production baseline: understand the codebase, resolve reliability and security issues, improve tests and support releases. Later work may include transaction approval functionality and post-quantum signing in collaboration with cryptography specialists.

Responsibilities:
Virtual Signer Engineering
— Maintain and improve the Go Virtual Signer, including signing orchestration, communication between participants, encrypted storage and recovery from failures.
— Investigate concurrency, timeouts, interrupted sessions, network failures and service restarts; review outstanding pull requests and address race conditions.
— Improve logging and visibility, assess the existing implementation critically and make careful, maintainable changes.
— Support agreed transaction approval features and future post-quantum signature work.
 

Cryptography, SDKs & Cross-Platform Integration
— Maintain integrations with MPC and threshold-signature libraries, working with cryptography specialists where changes affect protocol security.
— Contribute to shared SDKs and bindings connecting Go with Swift, Kotlin and JavaScript/TypeScript.
— Work with backend and mobile engineers to preserve API compatibility and consistent signing behaviour across releases.
 

Quality, Testing & Operations
— Improve automated tests for signing correctness, failure recovery and interoperability between virtual and mobile signers.
— Support Linux and Docker deployments, dependency upgrades, monitoring, release processes and operational documentation.
— Investigate production issues and occasionally assist with customer setup or logging problems.

Ownership & Technical Judgement
— Take primary ownership of a security-critical codebase with limited handover and independently establish a robust production baseline.
— Assess technical risks and trade-offs, explain decisions clearly and make incremental changes with sound security judgement.
— Collaborate pragmatically with backend, mobile, testing and cryptography specialists across time zone

Requirements:
Essential Technical Experience
— Strong hands-on production Go, including goroutines, channels, context cancellation, race detection, profiling and resource management.
— Experience owning production services, diagnosing complex failures and delivering well-tested fixes.
— Distributed-systems knowledge, including asynchronous messaging, retries, idempotency, state management and partial failures.
— Practical security engineering: authentication, encrypted storage, sensitive-data handling and safe logging.
— Applied cryptography concepts, including digital signatures, hashing, key management and signature verification.
— Automated testing, CI/CD, Linux, containers and production observability.
— Ability to understand an established codebase, make careful incremental changes and explain technical decisions clearly.

Strongly Preferred/Desirable Technical Experience
— JavaScript/TypeScript SDKs and mobile bindings, including asynchronous APIs, packaging, compatibility and Go/mobile interoperation.
— React Native/Expo, Swift or Kotlin; experience with mobile lifecycle, secure storage or native modules.
— MPC or threshold signatures, distributed key generation and changes to signing participants.
— Blockchain transaction signing, including signing payloads and chain-specific requirements.
— Confidential computing and hardware attestation, particularly AMD SEV-SNP, are especially valuable among the desirable skills.
— MQTT, Protocol Buffers, Prometheus or OpenTelemetry; familiarity with post-quantum signature schemes is also desirable for the longer-term roadmap.
 

Market Experience
— Experience with digital asset infrastructure, blockchain signing or MPC is valuable, but the priority is strong production Go and sound security judgement.
— Relevant experience in other security-critical distributed systems can also demonstrate fit.
— Candidates do not need experience with every desirable technology; evidence of ownership, careful delivery and learning across platform boundaries matters.

Soft Skills 
— Independent and able to understand an existing repository with limited handover.
— Strong security judgement, attention to correctness and a careful approach to critical signing systems.
— Able to assess implementation choices critically and explain risks and trade-offs clearly.
— Pragmatic and collaborative when working with backend, mobile and cryptography specialists.
— Comfortable diagnosing production failures and improving reliability through tested changes.

Sprinterra is an Acumatica ISV and Development Service Provider, working with Acumatica since 2013 and winner of the 2026 Acumatica Development Excellence Award.

We are looking for a manual QA engineer who wants to own the system, not just execute test cases. You will test Acumatica products, customizations, and integrations, become the internal expert on the functionality, and for the right person, grow into business analysis.

What you will do

• Test Acumatica customizations, ISV products, and integrations across releases and upgrades.
• Regression-test standard Acumatica functionality during upgrades, not only customizations.
• Design and maintain test cases and regression suites around business scenarios.
• Report and track defects in Jira, verify fixes, close the loop with developers.
• Review requirements before development and raise gaps and contradictions early.
• Build deep product knowledge: configuration, business logic, real customer usage.

What we expect

• 2+ years of manual QA on web-based business applications.
• Strong QA fundamentals: test design, documentation, defect lifecycle, regression.
• Working SQL for data verification.
• Willingness to learn a large ERP end to end and become the expert on it.
• English at B2 or above for direct work with US-based colleagues and partners.
• Active use of AI in daily QA work: generating test cases, summarizing specs and release notes, drafting defect reports, analyzing logs, preparing test data, and reviewing the output critically.

Significant plus

• ERP experience of any kind (Acumatica, SAP, NetSuite, Dynamics, Sage). The strongest differentiator.
• Background in accounting, finance, logistics, or operations.
• Previous application support experience on a business system: helpdesk, L2, or customer support.

Where it leads

Within 12 to 18 months the role expands into requirements gathering, functional specifications, discovery calls, and functional design, with certification and mentoring behind it.

How to apply and what to prepare

Before the interview, research Sprinterra. We will ask you to explain in detail what our Acumatica practice does: what services we provide, what we build, what we deliver, and to whom. A general answer will not pass.
