Location: Lisbon
Workplace: Hybrid
ROLE HIGHLIGHTS:
- Role: Forward Deployed Backend/DevOps Engineer
- Location: Portugal (Lisbon)
- Reports to: VP, Forward Deployed Engineering
- Working type: Hybrid (On-site at customer locations approx. 50% of time)
- Must be eligible and able to attain relevant national and NATO security clearances.
- Must be based in-country and native level speaker of the country you're deploying to.
WHY THIS ROLE MATTERS
In this role, you are the backend and infrastructure backbone defence and intelligence customers rely on. You deploy ICEYE's intelligence platform into secure (often air-gapped) environments and design the high-performance backend systems that move satellite data at scale — fast APIs, resilient services, tuned databases, automated infrastructure. Our stack: Python and Go services on Kubernetes, PostgreSQL and MongoDB, Terraform and Ansible, CI/CD pipelines that also run offline, cloud (AWS) and on-premises air-gapped clusters, with AI-assisted development as the default.
This is a ship-daily role: systems you build run mission-critical workloads analysts use to protect nations.
WHAT YOU'LL OWN
Platform deployment & operations
- Deploy ICEYE's intelligence platform into customer secure environments (on-premise, air-gapped networks, classified data centres).
- Install, upgrade and operate Kubernetes clusters and containerised applications (Docker) in customer environments — cloud and on-premises.
- Build infrastructure-as-code (Terraform, Ansible) and CI/CD pipelines that work without external internet access, including offline registries and artifact mirroring.
- Troubleshoot deployment and production issues in disconnected environments, from the application layer down to storage and networking.
High-performance backend systems
- Design and build APIs, services and data pipelines that handle large volumes of SAR imagery and intelligence data with low latency.
- Connect ICEYE systems to customer C4ISR infrastructure and intelligence tools through robust, well-designed integrations.
- Own database design and performance at production scale (PostgreSQL, MongoDB): schemas, indexing, tuning, replication and backup.
- Apply caching, queueing and horizontal scaling patterns deliberately — and capacity-plan for fixed on-premises hardware where you cannot simply scale out.
Reliability, security & observability
- Build monitoring, logging and alerting that work in restricted environments, so problems are found before the customer finds them.
- Harden deployments to meet customer security constraints; own backup, recovery and upgrade paths for systems that cannot go down.
- Run the infrastructure behind AI workloads shipped by the team — model serving, vector databases, GPU nodes — reliably and repeatably.
Customer engagement & rapid delivery
- Work embedded with intelligence analysts, operators and customer IT teams to understand operational and infrastructure requirements.
- Rapidly prototype and iterate (working systems first, polish later) to address immediate operational needs.
- Conduct hands-on training for customer administrators on platform operations.
- Feed deployment experience back to ICEYE's product and engineering teams as concrete technical requirements.
WHAT WE'RE LOOKING FOR
Must-haves
- 5+ years hands-on backend engineering building and operating production systems at scale.
- Strong programming skills in Python. You write typed, tested services and you are comfortable with async APIs. TypeScript is a plus.
- Proven experience designing high-performance backend systems: APIs, distributed services, messaging, caching and databases under real load. Experience with spatial, search, or vector workloads in Postgres is a plus.
- Production experience in both cloud (e.g., AWS) and on-premises environments — this role lives in both.
- Deep Docker and Kubernetes: deploy, debug, and upgrade clusters — not only consume them. GitOps and infrastructure-as-code experience. Pipelines that can run offline or on an isolated network are a plus.
- Observability as a habit: metrics, logs, and alerts are part of done.
- Infrastructure-as-code (Terraform, Ansible) and CI/CD experience, ideally including pipelines that run offline or in isolated networks.
- PostgreSQL and/or MongoDB at production scale: schema design, tuning, replication, backup and recovery.
- Observability as a habit: metrics, logging and alerting are part of done, not an afterthought.
- Builder mindset: ship fast, iterate with feedback, and prioritise working solutions over perfect architecture.
- Strong communication and customer engagement, able to work embedded with intelligence analysts / military operators.
- Strong spoken and written English, able to explain technical concepts to non-technical stakeholders.
- Willingness to travel 40–60% to customer sites within the region.
Nice to have
- Experience in defence, intelligence, or government operational environments.
- Deploying to on-prem data centres and/or air-gapped networks, including offline artifact and registry management.
- Event streaming and high-throughput data systems (e.g., Kafka or similar) at production scale.
- Deeper Kubernetes: operators, service mesh, multi-cluster, storage and networking internals.
- Security hardening and accreditation experience (system hardening baselines, audit and compliance in classified environments).
- Familiarity with geospatial data, satellite imagery, or remote sensing.
- Experience running infrastructure for AI/LLM workloads: GPU scheduling, model serving, vector databases.
- Active use of AI-assisted development tools as part of your daily workflow.
- Experience in defence tech (e.g., Palantir, Anduril, Scale AI, similar startups).

About the Role
We're looking for a Staff Engineer to own the smart wallet and account abstraction layer of Xsolla's Web3 platform. This is an individual contributor role with outsized technical scope: you'll be the technical anchor for how millions of players get an on-chain account they never have to think about — setting direction, making hard architectural calls, and raising the bar across the org.
Concretely, you'll own the account model behind Xsolla ZK, our zkSync-based L2, and the wallet that sits inside Xsolla App. Every player who signs in with Xsolla ID receives a deterministic, non-custodial smart account — derived from their identity claim, identical on every device, with private keys that never leave the client. That account is not a separate "wallet" screen: it is the player's inventory, and it backs minting, gifting, trading on our Bazaar marketplace, Merkle-based reward airdrops, gas sponsorship, and an in-app dApp browser that exposes the same signer to third-party applications through an EIP-1193 provider. You'll own the primitives underneath all of it: the ERC-4337 user operation lifecycle, EIP-7702 delegation, session keys and origin-bound Smart Sessions, paymaster and gas abstraction strategy, and the custody and recovery roadmap — including the move from raw key export to MPC custody.
You will own the strategy behind account abstraction, signing, and session management at scale, and evolve our smart account and permissioning model to meet both product and compliance needs. You operate with significant autonomy, but your decisions ripple across teams — so you'll spend real time building buy-in with engineering, product, security, and legal stakeholders, not just designing in isolation.
You are technically deep, calm under pressure, and comfortable being the escalation point when production wallet issues get hard — because in this domain, "hard" means a stuck user operation, a drained paymaster, or a signing prompt a player didn't understand. You write the RFCs and design docs that people actually read, and you create leverage for the broader engineering org through documentation, tooling, and mentorship — without needing a management title to do it.
Responsibilities
Own Smart Wallet & AA Architecture
— Own the technical strategy and architecture of our smart wallet platform, covering the account model, signing, session management, and gas abstraction at scale.
Design the Account & Signing Model
— Design and evolve our ERC-4337 user operation lifecycle (prepare → sign → submit → confirm), EIP-7702 delegation, deterministic address derivation from identity, and the session-key and permission primitives that let players act without a prompt on every transaction.
Own Gas Abstraction
— Set the paymaster and gas-sponsorship strategy: what we sponsor, how we meter and cap it, how we defend it from abuse, and how it degrades when sponsorship is unavailable.
Harden the dApp-Facing Surface
— Own the security model where our signer meets third-party applications: EIP-1193 / EIP-6963 provider behavior, origin-bound and policy-versioned sessions, trust tiers, and the transaction and signature confirmation flow. Define what a player is actually approving, and make sure the UI can prove it.
Drive Custody & Recovery
— Lead the custody roadmap from today's interim mechanisms toward MPC-based custody, and design recovery paths (passkeys, guardians, social recovery) that a non-crypto-native player can complete without losing assets.
Drive Cross-Team Technical Decisions
— Drive decisions on account architecture, SDK contracts, data modeling, and platform reliability, and build buy-in across the wallet, marketplace, SDK, mobile, and security teams.
De-Risk Proactively
— Identify systemic risks — key management, signature phishing, reorgs and indexer staleness, bundler and RPC dependencies, contract upgrade paths — and lead initiatives to resolve them before they become incidents.
Set Engineering Standards
— Define engineering standards, review critical code, contracts, and designs, and create leverage for the team through documentation, tooling, and mentorship.
Align with Stakeholders
— Collaborate with product, security, legal, and infra teams to align on roadmap and translate business and regulatory needs into well-scoped technical plans.
Own Production Escalations
— Serve as the go-to escalation point for complex production issues in the wallet and account abstraction domain.
What You Bring
Account Abstraction & Smart Wallets
ERC-4337 Depth
— Deep, hands-on understanding of ERC-4337: EntryPoint (v0.6 through v0.8), the UserOperation lifecycle, bundler and paymaster roles, validation rules (ERC-7562), gas estimation and its failure modes, counterfactual deployment, and signature validation for undeployed accounts (ERC-6492).
EIP-7702 & the Post-Pectra Landscape
— Working knowledge of EOA delegation, its interaction with ERC-4337 EntryPoint v0.8, and the trade-offs and risks it introduces (residual key authority, delegation phishing, storage collisions).
Smart Account Implementations
— Experience building on or extending production smart account implementations (Safe, Kernel, Biconomy, Coinbase Smart Wallet, or equivalent), and familiarity with modular account standards (ERC-7579 / ERC-6900).
Session Keys & Delegated Permissions
— Experience designing scoped, time-limited, policy-bound authority: session keys with TTL and contract allowlists, origin binding, permission revocation, and delegated-permission standards (ERC-7710 / ERC-7715).
Signature Schemes & Wallet Interfaces
— Practical command of EIP-712 typed data, ERC-1271 contract signatures, WebAuthn / passkey (P-256) signers, and the wallet-facing standards: EIP-1193, EIP-6963, EIP-5792 batched calls, ERC-7677 paymaster interfaces.
Production Wallet Experience
— Experience designing or operating a production smart wallet or account abstraction system serving real users and real value.
Production Crypto Track Record
Scale in a Major Crypto Organization
— Substantial engineering experience at a large crypto product or protocol organization — for example Coinbase, Kraken, Base, Safe, the Ethereum Foundation, Consensys / MetaMask — or a comparable wallet, exchange, or account-abstraction infrastructure team where wallet correctness and custody were core to the product.
Operational Judgment Under Value at Risk
— You have shipped and operated systems where a bug meant lost funds, and you can talk concretely about the guardrails, reviews, and rollback paths you put in place.
Smart Contracts & EVM
Solidity & EVM Fluency
— Ability to read, review, and write account, paymaster, and module contracts; gas-aware design; upgradeability and migration patterns; working effectively with external auditors.
L2 Specifics
— Understanding of L2 execution differences and how they affect wallet design: native account abstraction on zkSync-family chains, transaction and fee models, finality and reorg behavior, and RPC and indexer semantics.
Backend Engineering
Go Engineering
— Strong Go (Golang) engineering skills: idiomatic code, concurrency patterns, performance profiling.
TypeScript & SDK Design
— Ability to design and own client-side SDK surfaces in TypeScript that other engineering teams — internal and external — build on top of.
Distributed Systems
— Experience with distributed systems and their trade-offs (consistency, availability, failure modes), and with reconciling off-chain state against an authoritative on-chain result.
Data & Infrastructure
PostgreSQL
— Schema design, query optimization, migrations at scale.
Kubernetes
— Deploying, operating, and debugging services in a k8s environment.
Message Streaming
— Kafka or NATS — event-driven patterns, consumer groups, at-least-once delivery.
Git & CI/CD
— Git and modern CI/CD practices.
Security
Key Management
— Hands-on experience with key material in production: platform secure storage (Keychain / Keystore), HSMs, MPC or threshold signing, and the operational discipline around each.
Wallet Threat Modeling
— Solid grasp of the wallet attack surface: signature and delegation phishing, malicious dApp origins, replay and cross-chain replay, token approval abuse, and paymaster griefing and DoS.
Leadership
Cross-Team Initiative Leadership
— Proven ability to lead multi-quarter technical initiatives across teams.
Architectural Influence
— Track record of influencing architecture and standards beyond your immediate team.
Written & Verbal Communication
— You write RFCs and design docs that people actually read.
Nice to Have
Experience working in the video game industry, building or operating platforms for game developers, publishers, or players
Hands-on experience with the zkSync / Elastic Chain ecosystem (ZKsync OS, Matter Labs stack, native AA and paymaster flows, custom L2 operations)
Experience with embedded and ecosystem wallet providers or AA infrastructure vendors (thirdweb, Privy, Dynamic, Turnkey, Pimlico, Alchemy, Biconomy, ZeroDev, Safe{Core}) — and clear views on where to build versus buy
Experience with MPC / threshold custody, social recovery, or guardian-based recovery in a consumer product
Experience with NFT and token infrastructure at scale: ERC-721 / ERC-1155 / ERC-20 mechanics, marketplace contracts, Merkle-based airdrop and claim distribution, chain indexing services
Contributions to open-source wallet, security, or identity projects — including authorship or review of ERC / EIP standards
Familiarity with compliance requirements relevant to crypto consumer products: KYC / AML, geofencing, MiCA, SOC 2, ISO 27001, GDPR data minimization, audit logging
Experience with identity and auth integration for wallet derivation (OAuth 2.0 / OIDC, JWT verification, token scoping)
Background in platform or infrastructure engineering — building systems other engineers build on top of
Experience owning a mobile wallet surface (React Native / Expo, WebView provider injection, native signing UI)
Hands-on, up-to-date experience with modern AI tools (e.g. Claude, Copilot, Cursor) for code generation, review, and accelerating day-to-day engineering work
How We Work
Xsolla operates across multiple time zones, and the smart wallet underpins identity, ownership, and value transfer for every Web3 product we ship. Strong written communication is essential — your architectural decisions and designs need to stand on their own and be actionable without you in the room.
We value directness, technical depth, and follow-through. In this domain that means saying plainly when a design has custody, security, or reversibility implications, defending your position with evidence, and staying engaged until it's resolved. Where a decision touches player funds or key material, we expect the conservative call to be argued for explicitly rather than assumed.
Benefits
We are passionate about fostering a supportive environment for our team, so we prioritize the physical, mental, and emotional well-being of our employees and their families through a comprehensive Benefits Program. This includes medical, dental, and vision, PTO, and a personalized career roadmap for each employee. By investing in professional development through training and educational opportunities, we ensure that our team thrives both personally and professionally. Together, we’re not just building a business; we’re cultivating a community that values creativity, collaboration, and the transformative power of play.
