About Celero

Celero Communications is building the next generation of intelligent optical connectivity for AI infrastructure. Founded in 2024 by industry pioneers from Broadcom, Inphi, Marvell, and ClariPhy, Celero brings together decades of coherent DSP innovation with a focused mission to deliver the optical performance, power efficiency, and scalability required for tomorrow's AI-driven data centers. We believe the future of AI infrastructure will be defined not only by speed, but by intelligence, energy efficiency, and the ability to seamlessly move massive amounts of data across increasingly complex networks. Our mission is to build the technology foundation that makes this possible. Headquartered in Irvine, California, with engineering teams in Canada and Argentina, Celero develops advanced coherent Digital Signal Processing (DSP) solutions that enable high-bandwidth, low-power optical connectivity for hyperscale AI infrastructure.

About The Job

Celero is seeking an experienced, hands-on, and strategic Director of Firmware Engineering to lead the architecture, development, and validation of embedded firmware for our next-generation coherent DSP products for high-speed optical interconnects. Based onsite in Ottawa, Canada, you will own the firmware that brings our coherent DSP ASICs to life, controlling SerDes, framer, FEC, receive DSP, and analog/mixed-signal blocks, and make sure it is robust, high-performance, and production-ready from pre-silicon through mass deployment in hyperscale AI data centers. You will build and grow a high-performing firmware team, partner closely with digital design, analog/mixed-signal, DSP algorithm, verification, validation, and applications teams, and establish the processes, infrastructure,



and quality standards that let firmware scale across multiple product generations. Day to day, you will set technical direction while staying deeply engaged in architecture reviews, silicon bring-up planning, and critical debug, working with colleagues across Celero's teams in Irvine, Canada, and Córdoba, Argentina.

Key Responsibilities

- Firmware Strategy: Define and own the firmware architecture, roadmap, and execution strategy for coherent DSP product lines, aligned with product requirements and customer timelines
- Team Leadership: Build, mentor, and scale a team of firmware engineers and technical leads. Set transparent goals, drive accountability, and foster a culture of engineering excellence.
- Technical Authority: Serve as the primary firmware technical authority in cross-functional design reviews, architecture definition, and silicon bring-up planning
- Program Delivery: Own firmware schedules, resourcing, risk, and deliverables across multiple concurrent programs. Hold the team accountable to quality metrics from concept through production release.
- Datapath Control Firmware: Lead development of firmware to configure, control, and adapt high-speed SerDes, including link training, CTLE, FFE, and DFE adaptation, and link monitoring. Direct firmware for framer and FEC blocks, covering configuration, mode switching, performance monitoring, error statistics, and alarm handling.
- Receive DSP Firmware:



Oversee firmware for receive DSP functions such as timing recovery, adaptive equalization, carrier and phase recovery, and convergence and tracking control loops
- Analog Calibration and Management: Own calibration firmware for DAC, DCA, and PLL blocks, including power-up and background calibration, temperature and voltage tracking, and lock and status monitoring. Drive firmware for power management, health monitoring, telemetry, diagnostics, and host interfaces such as MDIO, I2C, and CMIS.
- Pre-silicon Verification: Establish and lead the pre-silicon firmware verification strategy using simulation, co-simulation, emulation, and FPGA prototyping. Partner with design verification teams to integrate firmware into RTL and AMS environments so firmware and hardware are validated together before tape-out.
- Regression and Quality: Build and maintain automated firmware regression infrastructure, including continuous integration, nightly regressions, coverage metrics, and pass/fail dashboards. Define coding standards, code review practices, release processes, and quality metrics for production-grade firmware.
- Bring-Up and Customer Support: Drive post-silicon bring-up, characterization support, and debug with validation, analog, and DSP teams. Support key customers and field applications teams during design-in, interoperability testing, and qualification, and work with systems, architecture, and product management to turn customer requirements into firmware features.
