Job description

Описание:

Tangem is a high-tech company in the blockchain sector was founded in 2017, headquartered in Zug, Switzerland, with branches in North America, Eastern Europe, and APAC. We’re looking for a hands‑on Tech Lead to own the technical direction and architecture of our Investment & Growth stream. You’ll work across mobile, backend, and blockchain, ensuring all components work reliably together.

Задачи:

Own technical architecture across mobile, backend, and blockchain components within the Grow stream; Get involved at the start of each major feature to define architecture, identify technical risks, and ensure smooth integration between systems; Review architecture decisions across teams and make sure mobile, backend, and blockchain components work reliably together; Own the provider layer across swap, on‑ramp, staking, and venue integrations; Design transaction lifecycle handling for money-moving flows: idempotency, state machines for long-running operations, retries, partial fills, stalled transactions, and reconciliation with partners; Lead technical evaluation and onboarding of aggregators, on‑ramp providers, staking providers, exchanges, and perp venues. Own end-to-end delivery for all Grow sub-streams: scope, estimates, dependencies, release plan, and launch; Coordinate technical decisions and dependencies across iOS, Android, backend, and blockchain teams; Run one delivery plan across sub-streams competing for shared engineering capacity and negotiate trade‑offs; Manage dependencies on shared platform teams and the Store and Spend streams; Report status, risks, and forecasts to the CTO. Provide technical leadership across the stream, working closely with functional engineering leads; Support engineers through technical guidance, feedback, and hiring; Own on‑call and incident response wherever user funds are in motion, with severity levels and MTTR targets; Build deeper domain expertise across teams, particularly around execution, settlement, and custody.

Требования:

8+ years in engineering, with 3+ years of technical leadership experience delivering consumer products in production; Strong hands‑on architecture experience across mobile, backend, and blockchain systems. Able to design and review technical solutions across all three areas, identify integration risks, and guide implementation; Experience with Kotlin or Node.js. Strong understanding of backend architecture, APIs, microservices, asynchronous communication, and distributed systems; Solid mobile engineering knowledge. Understands iOS and Android architecture, security, performance, and release processes. Able to review technical decisions and identify risks; Strong blockchain fundamentals. Understands how smart contracts work and interact with applications, common blockchain standards (including EVM/EIP/ERC concepts), transaction execution, and basic smart contract security risks. Hands‑on smart contract development is not required; Still technical. Able to investigate production issues and debug failed transactions end to end. This is not a purely managerial role. Multi‑chain in practice: EVM plus at least one of Solana, TON, Bitcoin/UTXO, or Cosmos. Transaction lifecycle, fee and nonce management, re‑orgs, token approvals, address derivation, and signing constraints; DeFi integration: has shipped DEX aggregation and routing, staking (delegation, unbonding, reward accounting), or yield vaults. Treats slippage, MEV, and quote decay as engineering problems; Trading‑venue integration: experience with exchange APIs in production — REST and WebSocket, rate limits, order lifecycle, deposits and withdrawals, settlement, and custody boundaries. Can explain how a quote becomes a fill and what breaks in between; Money‑movement correctness: idempotency, exactly‑once semantics, reconciliation, long‑running state machines, and observability. Has been on call for systems where a bug costs users money; Mobile delivery: has shipped with iOS and Android teams — release trains, backward compatibility across app versions, feature flags, and forced upgrades; Experience coordinating architecture and delivery across multiple teams or workstreams; Has managed technical relationships with third‑party providers, including holding them accountable. Будет плюсом: Has built systems where settlement, reconciliation, and order lifecycle carried real consequences: brokerage, CFD, payments, or PSP; Derivatives literacy — margin, funding rates, liquidation mechanics. Directly relevant to the Hyperliquid sub‑stream; Prediction markets or event contracts. Directly relevant to the Polymarket sub‑stream; Regulated delivery: MiCA and CASP, travel rule, geo‑restriction design, KYC and AML flows; Security engineering around signing flows, key material, and third‑party risk.

Условия:

Stability, development, participation in the future unicorn’s growth; Remote work from anywhere in the world; Competitive salary in EUR/USDT; Unlimited vacation; Birthday presents; Compensation for the purchase of necessary technical devices for the work; Paid sick leaves.
